Strong link found between victimization, substance abuse

ScienceDaily (Feb. 28, 2011) — A strong link between victimization experiences and substance abuse has been discovered by researchers at the University of Illinois at Chicago.

The correlation is especially prevalent among gays, lesbians and bisexuals — more so than in heterosexuals, says Tonda Hughes, professor and interim head of health systems science in the UIC College of Nursing. Hughes is lead author of the study, published in the journal Addiction.

Researchers compared victimization experiences of unwanted sexual activity, neglect, physical violence, and assault with a weapon, across four sexual-identity subgroups — heterosexual, gay or lesbian, bisexual, or “not sure.” The study used data collected nationally from 34,635 adults from the National Epidemiologic Survey on Alcohol and Related Conditions.

Hughes and her research team wondered if sexual-minority women and men are at a heightened risk for victimization. The results, Hughes said, showed that they are.

Lesbian and bisexual women were more than twice as likely as heterosexual women to report any victimization over their lifetime. Lesbians, gay men and bisexual women also reported a greater number of victimization experiences than did heterosexuals. Three times as many lesbians as heterosexual women reported childhood sexual abuse.

One possible explanation for this disproportionality, Hughes said, is that lesbians are more willing to acknowledge and report this experience.

“Gays and lesbians tend to be more self-reflective,” she said. “This means they are more likely to think about and report negative or stigmatizing life experiences. Heterosexuals may not be inclined to do so.”

Gay men also had high rates of victimization, with about half of them reporting any lifetime victimization. They reported significantly higher rates of childhood sexual abuse, childhood neglect, partner violence and assault with a weapon than heterosexual men.

Not only are there higher rates of violence and victimization among sexual minorities, but there is also a higher rate of substance abuse, Hughes said.

Regardless of sexual identity, women who reported two or more victimization experiences had two to four times the prevalence of alcohol dependence, drug abuse or drug dependence as women who reported no victimization, she said.

The research also concluded that gay, lesbian and bisexual youth may use substances to cope with adverse psychological and interpersonal effects of victimization, increasing the risk for further victimization from others, she said.

The study was funded through grants from the National Institute on Drug Abuse and the National Institute on Alcohol Abuse and Alcoholism, two of the National Institutes of Health.

Other authors on the Addiction paper were Sean Esteban McCabe, Brady West and Carol Boyd of the University of Michigan and Sharon Wilsnack of the University of North Dakota.

Cannabis ingredient can help cancer patients regain their appetites and sense of taste, study finds

ScienceDaily (Feb. 25, 2011) — The active ingredient in cannabis can improve the appetites and sense of taste in cancer patients, according to a new study published online in the cancer journal, Annals of Oncology.

Loss of appetite is common among cancer patients, either because the cancer itself or its treatment affects the sense of taste and smell, leading to decreased enjoyment of food. This, in turn, can lead to weight loss, anorexia, a worse quality of life and decreased survival; therefore, finding effective ways of helping patients to maintain a good diet and consume enough calories is an important aspect of their treatment.

Researchers in Canada ran a small pilot study from May 2006 to December 2008in 21 adult patients with any advanced cancer (except brain cancer) who had been eating less as a result of their illness for two weeks or more. All were either being treated with chemotherapy or had been in the past. The patients were randomly assigned to receive medication from a pharmacist in a double-blind manner, which meant that neither the patients nor the doctors knew which treatment they were receiving. Eleven patients received oral capsules containing delta-9-tetrahydrocannabinol (THC) — the main psychoactive ingredient in cannabis — and eight patients were assigned to the control group to receive placebo capsules. The active capsules contained 2.5mg of THC and the patients took them once a day for the first three days, twice a day thereafter, and they had the option to increase their dose up to a maximum of 20mg a day if they wished; however, most followed the dosing protocol, with three patients in both groups increasing their dose to three times a day. The treatment ran for 18 days.

From patient answers to questionnaires conducted before, during and at the end of the trial, the researchers found that the majority (73%) of THC-treated patients reported an increased overall appreciation of food compared with patients receiving placebo (30%) and more often stated that study medication “made food taste better” (55%) compared with placebo (10%).

The majority of THC-treated patients (64%) had increased appetite, three patients (27%) showed no change, and one patient’s data was incomplete. No THC-treated patients showed a decrease in appetite. By contrast, the majority of patients receiving placebo had either decreased appetite (50%) or showed no change (20%).

Although there was no difference in the total number of calories consumed by both groups, the THC-treated patients tended to increase the proportion of protein that they ate, and 55% reported that savoury foods tasted better, whereas no patients in the placebo group reported an increased liking for these foods. (Cancer patients often find that meat smells and tastes unpleasant and, therefore, they eat less of it).

In addition, THC-treated patients reported better quality of sleep and relaxation than in the placebo group.

Dr Wendy Wismer (PhD), associate professor at the University of Alberta (Edmonton, Canada), who led the study, said: “This is the first randomised controlled trial to show that THC makes food taste better and improves appetites for patients with advanced cancer, as well as helping them to sleep and to relax better. Our findings are important, as there is no accepted treatment for chemosensory alterations experienced by cancer patients. We are excited about the possibilities that THC could be used to improve patients’ enjoyment of food.

“Decreased appetite and chemosensory alterations can be caused by both cancer and its treatment; untreated tumours cause loss of appetite, and by itself, chemotherapy also causes loss of appetite. In any individual patient, some part of both of these effects is usually present.

“It’s very important to address these problems as both appetite loss and alterations to taste and smell lead to involuntary weight loss and reduce an individual’s ability to tolerate treatment and to stay healthy in general. Additionally, the social enjoyment of eating is greatly reduced and quality of life is affected. For a long time everyone has thought that nothing could be done about this. Indeed, cancer patients are often told to ‘cope’ with chemosensory problems by eating bland, cold and odourless food. This may well have the result of reducing food intake and food enjoyment.”

The researchers say that larger, phase II trials should test their findings further, but, in the meantime Dr Wismer thinks that doctors could consider THC treatment for cancer patients. “It could be investigated for any stage of cancer where taste and smell dysfunction and appetite loss has been indicated by the patient,” she said. In addition, treatment would not necessarily have to be limited to the 18 days of the study. “Long term therapy with cannabinoids is possible, however, in each case this would be up to the patient’s physician to determine.”

Although the study was unable to show that THC treatment could increase total calorie intake, Dr Wismer said this was unsurprising. “In the healthy adult population, we know from personal experience that we usually eat more of something if it tastes better. However, in this advanced cancer population, there is a real struggle with appetite; normal appetitive pathways do not seem to be functioning. We know from our earlier work that individuals with advanced cancer have diminished appetite and have to make a big conscious effort to eat; they are motivated to eat simply to survive. So, although THC did not significantly increase total calorie intake, the fact that it improved appetite and protein intake is important.”

This work was supported by the Canadian Institutes of Health Research, the Alberta Cancer Board, Alberta Heritage Foundation for Medical Research, and the Natural Sciences and Engineering Research Council of Canada.

National anti-drug campaign in US succeeds in lowering marijuana use, study suggests

ScienceDaily (Feb. 23, 2011) — The federal anti-drug campaign “Above the Influence” appears to have effectively reduced marijuana use by teenagers, new research shows.

A study of more than 3,000 students in 20 communities nationwide found that by the end of 8th grade, 12 percent of those who had not reported having seen the campaign took up marijuana use compared to only 8 percent among students who had reported familiarity with the campaign.

The researchers said they believe this is the first independent study to find evidence for the effectiveness of the “Above the Influence” campaign, which was initially funded at nearly $200 million a year when it began in 2005.

Evidence for the success of “Above the Influence” is especially heartening because the primary independent evaluation of its predecessor campaign, “My Anti-Drug,” showed no evidence for success, said Michael Slater, principal investigator of the new study and professor of communication at Ohio State University.

“The ‘Above the Influence‘ campaign appears to be successful because it taps into the desire by teenagers to be independent and self-sufficient,” Slater said.

For example, one television ad in the campaign ends with the line “Getting messed up is just another way of leaving yourself behind.”

Campaigns that only emphasize the risk of drug use may not be effective with many teens.

“We know that many teenagers are not risk avoidant, and consider the risks of marijuana to be modest. A campaign that merely emphasizes already-familiar risks of marijuana probably won’t reach the teens who are most likely to experiment with drugs,” he said.

The study appears in the March 2011 issue of the journal Prevention Science.

Slater said this study was not originally designed to study the effectiveness of the “Above the Influence” campaign, which is sponsored by the federal Office of National Drug Control Policy (ONDCP).

Instead, the study was going to examine the effectiveness of a very similar, but more localized anti-drug campaign called “Be Under Your Own Influence.” This theme was developed years before the “Above the Influence” campaign by study co-author Kathleen Kelly, professor of marketing at Colorado State University.

It involved in-school media and promotional materials combined with community-based efforts. Like the “Above the Influence” campaign, it emphasized that drug use undermines the ability of teens to achieve their goals and act independently.

Slater said that members of his research team presented preliminary results supporting the effectiveness of “Be Under Your Own Influence” to the ONDCP and to Partnership for Drug Free America, which oversees creative efforts for the national campaign, in 2003, about two years before “Above the Influence” was launched. However, the researchers did not have any direct input into the development of the “Above the Influence” campaign.

Slater said the approaches are very similar.

“‘Above the Influence’ uses the same approach — focusing on the inconsistency of substance use with teens’ aspirations and autonomy — that we developed,” he said.

A study published in 2006 of “Be Under Your Own Influence” showed that it reduced by about half the number of students who began using marijuana and alcohol during the two years of the project, compared to students in communities without the program.

This new study was designed to replicate and extend the previous research, Slater said. In the 20 communities involved in the study, schools received some combination of some, all or none of the “Be Under Your Own Influence” materials.

The researchers surveyed 3,236 students who were about 12 years old when the study began in 2005. They were surveyed four times beginning in 7th grade and ending about a year and a half later.

The researchers didn’t know that the ONDCP would be launching its “Above the Influence” campaign about the same time this new study began. As a result, though, the researchers asked students about their exposure to the national campaign during the second through fourth surveys.

The results of this study showed that the ONDCP campaign appeared to be very successful at reaching students: up to 79 percent of students surveyed said they had seen the ads.

“There was wide exposure to the national campaign, and it really swamped the effects of our local effort,” Slater said. “It took over, and we didn’t see any independent effects for the ‘Be Under Your Own Influence‘ campaign.”

But it was really the message of “Above the Influence” that mattered in reducing marijuana use — not the fact that it was a national campaign, he said. In their previous study, the researchers found that “Be Under Your Own Influence” showed strong local anti-drug effects, even though the national “My Anti-Drug” campaign was going on.

“‘Above the Influence‘ has succeeded more than its predecessor attempt to influence teens,” Slater said.

The effectiveness of the ONDCP campaign can be seen in the way it appeared to influence attitudes of teens who viewed the ads.

Results showed that teens who had seen the “Above the Influence” ads were more likely than others to say that marijuana use was inconsistent with being autonomous and independent and that it would interfere with their goals and aspirations.

“The teens seemed to pick up on the messages that the campaign promoted,” Slater said.

“The campaign really works to honor teens’ interest in becoming autonomous and achieving goals and stays away from messages that don’t really reach the teens who are most likely to use marijuana.”

Slater says study limitations include the fact that findings regarding the ONDCP campaign were based on survey results and not a randomized, experimental design in which some youth saw the ONDCP campaign and others did not. Another limitation was that the study, while taking place in 20 communities around the U.S., did not use a random sample of U.S. youth.

Other co-authors of the study were Frank Lawrence of Penn State University; Linda Stanley of Colorado State University; and Maria Leonora G. Comello of the University of North Carolina.

The research was supported by a grant from the National Institute on Drug Abuse.

New study finds no cognitive impairment among ecstasy users

ScienceDaily (Feb. 16, 2011) — The drug known as ecstasy has been used by 12 million people in the United States alone and millions more worldwide. Past research has suggested that ecstasy users perform worse than nonusers on some tests of mental ability. But there are concerns that the methods used to conduct that research were flawed, and the experiments overstated the cognitive differences between ecstasy users and nonusers.

In response to those concerns, a team of researchers has conducted one of the largest studies ever undertaken to re-examine the cognitive effects of ecstasy, funded by a $1.8 million grant from the National Institute on Drug Abuse (NIDA) and published in the journal Addiction. The study was specifically designed to minimize the methodological limitations of earlier research.

In contrast to many prior studies, ecstasy users in the new study showed no signs of cognitive impairment attributable to drug use: ecstasy use did not decrease mental ability.

Lead author John Halpern is quick to point out that this group of researchers is not the first to identify limitations in prior studies of ecstasy users. “Researchers have known for a long time that earlier studies of ecstasy use had problems that later studies should try to correct. When NIDA decided to fund this project, we saw an opportunity to design a better experiment and advance our knowledge of this drug.”

The researchers fixed four problems in earlier research on ecstasy. First, the non-users in the experiment were members of the “rave” subculture and thus repeatedly exposed to sleep and fluid deprivation from all-night dancing — factors that themselves can produce long-lasting cognitive effects.

Second, participants were screened for drug and alcohol use on the day of cognitive testing, to make sure all participants were tested while ‘clean’.

Third, the study chose ecstasy users who did not habitually use other drugs that might themselves contribute to cognitive impairment.

Finally, the experiment corrected for the possibility that any cognitive impairment shown by ecstasy users might have been in place before they started using the drug.

The resulting experiment whittled 1500 potential participants down to 52 carefully chosen ecstasy users, whose cognitive function was compared against 59 closely-matched non-users, with tests administered at several stages to make sure participants were telling the truth about their drug and alcohol use.

So does this mean that ecstasy really is the risk-free, hangover-free, miracle drug that lets young ravers and gamers party all weekend without having to pay the price?

Says Halpern, “No. Ecstasy consumption is dangerous: illegally-made pills can contain harmful contaminants, there are no warning labels, there is no medical supervision, and in rare cases people are physically harmed and even die from overdosing. It is important for drug-abuse information to be accurate, and we hope our report will help upgrade public health messages. But while we found no ominous, concerning risks to cognitive performance, that is quite different from concluding that ecstasy use is ‘risk-free’.”

Kids with ADHD much more likely to develop substance abuse problems as they age, study finds

ScienceDaily (Feb. 12, 2011) — Children with attention-deficit hyperactivity disorder are two to three times more likely than children without the disorder to develop serious substance abuse problems in adolescence and adulthood, according to a study by UCLA psychologists and colleagues at the University of South Carolina.

“This greater risk for children with ADHD applies to boys and girls, it applies across race and ethnicity — the findings were very consistent,” said Steve S. Lee, a UCLA assistant professor of psychology and lead author of the study. “The greater risk for developing significant substance problems in adolescence and adulthood applies across substances, including nicotine, alcohol, marijuana, cocaine and other drugs.”

Lee and his colleagues analyzed 27 long-term studies that followed approximately 4,100 children with ADHD and 6,800 children without the disorder into adolescence and young adulthood — in some cases for more than 10 years. These carefully designed, rigorous and lengthy studies, Lee said, are the “gold standard” in the field.

The research by Lee and his colleagues, the first large-scale comprehensive analysis on this issue, is published online this week in the journal Clinical Psychology Review and will appear in a print edition later this year.

The researchers combined all the published studies that met rigorous criteria and analyzed them together. They found that children with ADHD were at greater risk for serious problems such as addiction, abuse and trying to quit but being unable to, Lee said.

“Any single study can be spurious,” he said, “but our review of more than two dozen carefully designed studies provides a compelling analysis.”

ADHD is common, occurring in approximately 5 percent to 10 percent of children in the U.S., and figures in many other industrialized countries with compulsory education are comparable, according to Lee.

Symptoms of the disorder are common in children and include being easily distracted, fidgeting, being unable to complete a single task and being easily bored. However, to receive a diagnosis of ADHD, a child must have at least six of nine symptoms of either hyperactivity or inattention, and the child’s behavior must be causing problems in his or her life. The vast majority of children with ADHD have at least six symptoms in both categories, Lee said.

In addition, the symptoms must have started before age seven, must be present in multiple settings — at home and school, for example — and must be adversely affecting functioning. They must not be explainable by any medical condition or any other mental disorder.

As children with ADHD enter adolescence and adulthood, they typically fall into three groups of roughly equal size, Lee said: one-third will have significant problems in school and socially; one-third will have moderate impairment; and one-third will do reasonably well or have only mild impairment.

Parents should monitor their children, said Lee, who noted that early intervention with a mental health professional is often helpful. A diagnosis of ADHD must be made by a mental health professional such as a child psychologist or psychiatrist and not by a parent or teacher.

Co-authors on the study are Kathryn Humphreys, a UCLA graduate student in clinical psychology; Kate Flory, an assistant professor of psychology at the University of South Carolina; Rebecca Liu, a UCLA undergraduate who worked in Lee’s laboratory; and Kerrie Glass, a graduate student in psychology at the University of South Carolina.

The research was federally funded by the National Institutes of Health’s National Institute on Alcohol Abuse and Alcoholism.

Sharp rise in street drug usage among stroke patients, study shows

ScienceDaily (Feb. 9, 2011) — While smoking and alcohol use remained relatively stable over a 13-year study period, street drug use among stroke patients rose more than nine-fold, according to new research from the University of Cincinnati (UC).

The findings are being presented on February 9, in Los Angeles at International Stroke Conference (ISC) 2011, the annual meeting of the American Stroke Association, by Felipe De los Rios, MD, of the UC Department of Neurology and the UC Neuroscience Institute. De los Rios is a fourth-year resident in the neurology department.

The research is part of the Greater Cincinnati/Northern Kentucky Stroke Study, begun in 1993 at the UC College of Medicine, which is funded by the National Institutes of Health (NIH) and identifies all hospitalized and autopsied cases of stroke and transient ischemic attack (TIA) in a five-county region. The NIH also funded the study led by De los Rios.

“We know that stroke incidence in younger age groups has increased over time in our region,” says De los Rios, referring to UC research presented at last year’s International Stroke Conference. “With street drug use more prevalent at younger ages, this could help explain that phenomenon.”

Researchers examined three one-year periods: July 1993 to June 1994, 1999 and 2005, the latest year for which complete statistics are available. While current smoking (rising from 21 percent to 24 percent) and heavy alcohol use (dropping from 6 percent to 5 percent) remained relatively stable, street drug use including marijuana and cocaine/crack, among others, rose from 0.5 percent in 1993-94 to 4.6 percent in 2005. (It was 1.5 percent in 1999.)

Street drug use information came from patients’ charts or positive urine/blood tests. Current smoking was defined as present within the past three months; heavy alcohol use constituted three or more servings per day.

“The number of stroke subjects with street drug use is not trivial,” says de los Rios, adding that the heaviest usage (21 percent) among stroke patients in 2005 was in the under-35 age group.

Data presented by UC researchers at ISC 2010 in San Antonio, also using information from the Greater Cincinnati/Northern Kentucky Stroke Study, showed the proportion of all strokes under age 45 in the area was up to 7.3 percent in 2005 from 4.5 percent in 1993-94 and 5.5 percent in 1999.

Drug-abusers have difficulty to recognize negative emotions as wrath, fear and sadness, study finds

ScienceDaily (Feb. 3, 2011) — University of Granada scientists have analyzed the relation between drug abuse and recognition of basic emotions (happiness, surprise, wrath, fear, sadness and disgust) by drug-abusers. Thus, the study revealed that drug-abusers have difficulty to identify negative emotions by their facial expression: wrath, disgust, fear and sadness.

Further, regular abuse of alcohol, cannabis and cocaine usually affects abusers’ fluency and decision-making. Consuming cannabis and cocaine negatively affects work memory and reasoning. Similarly, cocaine abuse is associated to alterations in inhibition.

For the purpose of this study, researchers carried out a neuropsychological evaluation (with neurocognitive evaluation and emotional processing tests) out of a total of 123 polysubstance abusers and 67 no-drug users with similar social and demographical variables (age and schooling).

A Sample Including Polysubstance-Abusers

The target population were individuals who consumed drugs as cocaine, cannabis, heroin, alcohol, MDMA and methamphetamine, and who were enrolled in two rehabilitation projects Proyecto Hombre and Cortijo Buenos Aires in the province of Granada.

The main author of this research was María José Fernández Serrano ­­-supervised by professors Miguel Pérez García and Antonio Javier Verdejo García- of the Department of Personality and Psychological Treatment and Evaluation, University of Granada.

The study revealed that 70% of drug abusers presented some type of neuropsychological deterioration, regardless the type of substance consumed. Deterioration was registered in major degree in the working memory, and in fluency, flexibility, planning, multitask ability and interference.

Fernández Serrano thinks that the results obtained “should be employed to develop political and social policies aimed at promoting adequate rehab programs adapted to the neuropsychological profile of drug-abusers.”

The research conducted at the University of Granada has been the first to study the prevalence of psychological deterioration in drug-abusers enrolled in therapeutic communities. Further, although other studies have been conducted on emotional recognition by drug users, they were focused on recognition as a unit process. However, the scientists from Granada have analysed for the first time the relation between drug abuse and recognition of basic emotions (happiness, surprise, wrath, fear, sadness and disgust).

The path is peace.

Distinguished members of Congress, ladies and gentlemen, dear friends, it is my pleasure to have this opportunity to talk with you about how we can share our insight, our compassion and our understanding in order to better serve those we want to serve and help heal the wounds that have divided our nation and the world.

When you sit in your car on the way to work, you might like to use that time to come home to yourself and touch the wonders of life. Instead of allowing yourself to think of the future, you might like to pay attention to your breath and come home to the present moment. We breathe in and out all day, but we are not aware that we are breathing in and breathing out. The practice of bringing our attention to our breath is called mindful breathing: Breathing in, I know I am alive. Breathing out, I smile to life. This is a very simple practice. If we go home to our in-breath and out-breath and breathe mindfully, we become fully alive in the here and now.

In our daily lives, our bodies are present, but our minds might be elsewhere, caught in our projects, our worries and our anxieties. Life is only available in the present moment. The past is already gone; the future is not yet here. When we establish ourselves in the present moment we are able to live our moments deeply and to get in touch with the healing, refreshing and nourishing elements that are always within us and around us.

With this energy of mindfulness, we can recognize our pain and embrace it tenderly like a mother whose baby is crying. When a baby cries, the mother stops everything she is doing and holds the baby tenderly in her arms. The energy of the mother will penetrate into the baby and the baby will feel relief. The same thing happens when we recognize and embrace our own pain and sorrow. If we can hold our anger, our sorrow and our fear with the energy of mindfulness, we will be able to recognize the roots of our suffering. We will be able to recognize the suffering in the people we love as well.

Mindfulness helps us to not be angry at our loved ones, because when we are mindful, we understand that our loved ones are suffering as well. The person you love has a lot suffering and has not had a chance to be listened to. It is very important to take the time to sit down and listen with compassion. We call this practice “deep listening.” Deep listening can be used with the practice of loving speech to help restore communication with the people you care about. To listen like this is to give the other person a chance to empty his or her heart. If you can keep your compassion alive during that time—even if what the other person says is full of accusations and bitterness—it will not touch off irritation and anger in you. Listen in order to help the other person to suffer less.

When you communicate with compassion, you are using language that does not have the elements of anger and irritation in it. In this way we can help each other remove wrong perceptions. All the energies of anger, hatred, fear and violence come from wrong perceptions. Wrong perceptions result in a lot of anger, mistrust, suspicion, hate and terrorism. You cannot remove wrong perceptions through punishment. You have to do it with the tools of deep and compassionate listening and loving speech. With deep, compassionate listening and loving speech, we can bring harmony to our families, and our communities can become communities of understanding, peace and happiness.

When I was in India a number of years ago, I spoke to Mr. R. K. Narayan, a member of the Indian parliament, about the practice of deep listening and compassionate dialogue in legislative bodies. When you represent the people, you are expected to offer the people the best of your understanding and compassion. I said that a legislative assembly could become a community with a lot of mutual understanding and compassion. It could have strong collective insight to support the decision-making process and the people of the nation. Here in Washington, before a session of Congress, one person could read a short meditation: “Dear colleagues, we are elected by our people and our people expect us to listen to each other deeply and to use the kind of language that can convey our wisdom and insight. Let us bring together our individual experiences and wisdom so that we can offer our collective insight and make the best decisions for the country and the people.”

When a member of Congress is speaking from her insight with this kind of language, she is offering the best of herself. If we only act and speak the party line, then we are not offering the best compassion and understanding we have.

Members of Congress are very concerned about the levels of violence in our families, in our schools and in our society. Each concerned person may have his or her own ideas and insights about how to bring down that level of violence. If we can combine all our insights and experiences we will have the collective insight that will help to decrease the amount of violence in our society. If we are not able to listen to our colleagues with a free heart, though—if we only consider and support ideas from our own party—we are harming the foundation of our democracy. That is why we need to transform our community—in this case the Congress—into a compassionate community. Everyone would be considered a brother or sister to everyone else. Congress would be a place where we learn to listen to everyone with equal interest and concern. The practice of deep and compassionate listening and loving speech can help to build brotherhood, can remove discrimination and can bring about the kind of insight that will be liberating to our country and to our people.

Two days after the events of September 11th, I spoke to 4,000 people in Berkeley, California. I said that our emotions are very strong right now, and we should calm ourselves down. With lucidity and calm we would know what to do and what not to do in order not to make the situation worse. I said that the terrorists who attacked the World Trade Center must have been very angry. They must have hated America a lot. They must have thought of America as having tried to destroy them as individual people, as a religion, as a nation, and as a culture. I said that we had to find out why they did such a thing to America.

America’s political leaders can ask the question, calmly and with clarity: “What have we done that has made you suffer so much?” America’s political leaders can say, “We want to know about your suffering and why you hate us. We may have said something or done something that gave you the impression that we wanted to destroy you. But that is not the case. We are confused, and that is why we want you to help us understand why you have done such a thing to us.”

We call this loving or gentle speech. If we are honest and sincere, they will tell us how they feel. Then we will recognize the wrong perceptions they have about themselves and about us. We can try to help them to remove their wrong perceptions. All these acts of terrorism and violence come from wrong perceptions. Wrong perceptions are the ground for anger, violence and hate. You cannot remove wrong perceptions with a gun.

When we listen deeply to another person, we not only recognize their wrong perceptions, but we also identify our own wrong perceptions about ourselves and about the other person. That is why mindful dialogue and mindful communication is crucial to removing anger and violence.

It is my deepest hope that our political leaders can make use of such instruments to bring peace to the world. I believe that using force and violence can only make the situation worse. Since September 11th, America has not been able to decrease the level of hate and violence on the part of the terrorists. In fact, the level of hate and violence has increased. It is time for us to go back to the situation, to look deeply and to find another less costly way to bring peace to us and to them. Violence cannot remove violence—everyone knows that. Only with the practice of deep listening and gentle communication can we help remove wrong perceptions that are at the foundation of violence.

America has a lot of difficulty in Iraq. I think that America is caught in Iraq in the same way that America was caught in Vietnam. We have the idea that we have to go and destroy the enemy. That idea will never give us a chance to do the right thing to end violence. During the Vietnam War, America thought that it had to go to North Vietnam to bomb. The more America bombed, the more communists they created. I am afraid that the same thing is happening in Iraq. I think that it is very difficult for America to withdraw now from Iraq. Even if they want to leave, it is very difficult.

The only way for America to free itself from this situation is to help build the United Nations into a real body of peace so that the United Nations will take over the problem of Iraq and of the Middle East. America is powerful enough to make this happen. America should allow other nations to contribute positively to building the United Nations into a true organization for peace with enough authority to do its job. To me, that is the only way out of our current situation.

We have to wake up to the fact that everything is connected to everything else. Our safety and wellbeing cannot be individual matters anymore. If they are not safe, there is no way that we can be safe. Taking care of other people’s safety is taking care of our own safety. To take care of their well-being is to take care of our own well-being. It is the mind of discrimination and separation that is at the foundation of all violence and hate.

My right hand has written all the poems that I have composed. My left hand has not written a single poem. But my right hand does not think, “Left Hand, you are good for nothing.” My right hand does not have a superiority complex. That is why it is very happy. My left hand does not have any complex at all. In my two hands there is the kind of wisdom called the wisdom of nondiscrimination. One day I was hammering a nail and my right hand was not very accurate and instead of pounding on the nail it pounded on my finger. It put the hammer down and took care of the left hand in a very tender way, as if it were taking care of itself. It did not say, “Left Hand, you have to remember that I have taken good care of you and you have to pay me back in the future.” There was no such thinking. And my left hand did not say, “Right Hand, you have done me a lot of harm—give me that hammer, I want justice.” My two hands know that they are members of one body; they are in each other.

I think that if Israelis and Palestinians knew that they were brothers and sisters—that they are like my two hands—they would not try to punish each other anymore. The world community has not helped them to see that. If Israelis and Palestinians—and Muslims and Hindus—knew that discrimination was at the base of our suffering, they would know how to touch the seed of nondiscrimination in themselves. That kind of awakening—that kind of deep understanding—brings about reconciliation and well-being.

I believe that in America there are many people who are awakened to the fact that violence cannot remove violence. They realize there is no way to peace: peace itself is the way. Those people must come together and voice their concern strongly and offer their collective wisdom to the nation so the nation can get out of this current situation. Every one of us has the duty to bring together that collective insight. With that insight, compassion will make us strong and courageous enough to bring about a solution for the world.

Every time we breathe in, go home to ourselves and bring the element of harmony and peace into ourselves, that is an act of peace. Every time we know how to look at another living being and recognize the suffering in him that has made him speak or act like that, we are able to see that he is the victim of his own suffering. When that understanding is in us, we can look at this other person with the eyes of understanding and compassion. When we can look with the eyes of compassion, we don’t suffer and we don’t make the other person suffer. These are the actions of peace that can be shared with other people.

At Plum Village, there are several hundred people living together like a family in a very simple way. At Plum Village, we have had the opportunity to practice together as a community. We are able to build up brotherhood and sisterhood. Although we live simply, we have a lot of joy because of the amount of understanding and compassion that we can generate. We are able to go to many countries to offer mindfulness retreats so that people may have a chance to heal, transform and to reconcile. Healing, transformation and reconciliation always happen during our retreats. That can be very nourishing.

We have invited Israelis and Palestinians to Plum Village to practice with us. When they come they bring anger, suspicion, fear and hate. But after a week or two of the practices of mindful walking, mindful breathing, mindful eating and mindful sitting, they are able to recognize their pain, embrace it and find relief. When they are initiated to the practice of deep listening, they are able to listen to others and realize that people from the other groups suffer as they do. When you know that they also suffer from violence, from hate, from fear and despair, you begin to look at them with the eyes of compassion. At that moment you suffer less and you make them suffer less. Communication becomes possible with the use of loving speech and deep listening.

The Israelis and Palestinians always come together as a group at the end of their stay in Plum Village. They always report the success of their practice. They always go back to the Middle East intending to continue the practice and invite others to join them, so that those others might suffer less and help others to suffer less too.

I believe that if this practice could be done on the national level, it would bring about the same kind of effect. Unfortunately, our political leaders have not been trained in these practices of mindful breathing, mindful walking and embracing pain and sorrow to transform their suffering. They have been trained only in political science.

So I think we should all bring a spiritual dimension into our daily lives. We should be awakened to the fact that happiness cannot be found in the direction of power, fame, wealth and sex. If we look deeply around us, we see many people with plenty of these things, but they suffer very deeply. When you have understanding and compassion in you, you don’t suffer. You can relate very well to other people around you and to other living beings also. That is why a collective awakening about that reality is crucial.

One of the concrete things that Congress could do is to look deeply into the matter of consumption. We think that happiness is possible when we have the power to consume, but by consuming we bring into us a lot of toxins and poisons. The way we eat, the way we watch television and the way we entertain ourselves brings us a lot of destruction. Because we consume so much, the environment suffers. Learning to consume only the things that can bring peace and health into our body and into our consciousness is a very important practice. Mindful consumption is the practice that can bring us out of much of our unhappiness.

By consuming unmindfully, we continue to bring the elements of craving, fear and violence into ourselves. There is so much suffering in people. They consume because they do not know how to handle their suffering. Something should be done to help people go home to themselves and take care of their suffering. Congress could find ways to encourage people to consume mindfully and produce mindfully, instead of creating products that can bring toxins and craving into the hearts and bodies of people. Producing with responsibility should be our practice.

My strongest desire is that the members of Congress will have time to look into these matters and look deeply into the roots of their own suffering, the suffering of this nation, and the suffering around the world. This suffering does not have to continue. We already have the compassion and understanding necessary to heal the world. ©

Thich Nhat Hanh is a Zen teacher, poet and leader of the engaged Buddhist movement. A well-known antiwar activist in his native Vietnam, he was nominated for the Nobel Peace Prize by Martin Luther King, Jr. He is the author of more than forty books. This article is adapted from his talk to members of the United States Congress on September 10, 2003.

This is The Buddhas Love

One of the best parts of my job as editor of the Shambhala Sun is the chance to discuss dharma seriously, even intimately, with great teachers. I’m a Buddhist student before I’m a journalist, and the questions I ask are often ones that have deep meaning to me as a person and a practitioner. The result is less an interview, in the standard sense, than the record of a teaching that I received. This is a great honor and privilege for me, and I hope it is of benefit to you.   

I met Thich Nhat Hanh at Deer Park Monastery near San Diego, a mix of East and West, funky and elegant, mindful and playful. It sits in a little mountain valley in splendid isolation from the suburbs just a mile away. Many of its low, one-story buildings have the temporary feel of an army camp (it has been a nudist camp and a police training center) but its elegant new meditation hall is of majestic scale. Outside, young Vietnamese-American monks play basketball while elderly nuns in traditional conical hats sweep leaves off the dry ground, and earnest Western lay practitioners debate the dharma. The breakfast buffet is traditional Vietnamese fish alongside Corn Flakes and peanut butter, and everything stops when the clock chimes so people can practice a few moments of mindfulness.

I spoke with Thich Nhat Hanh for about an hour and quarter, and then he showed me the calligraphies, the ones in this issue, which he had done beforehand as a gift to the Shambhala Sun. Although he is best-known for his political and community-building work, I found he was so much more. I met a multidimensional teacher who was deep and realized, committed to both practice and community, steeped in traditional dharma and the ways of the world. He spoke directly to my heart, and if you get a chance to hear him teach, do. Words in print do not do him justice.

The Moment is Perfect

Take the time to eat an orange in mindfulness. If you eat an orange in forgetfulness, caught in your anxiety and sorrow, the orange is not really there. But if you bring your mind and body together to produce true presence, you can see that the orange is a miracle. Peel the orange. Smell the fruit. See the orange blossoms in the orange, and the rain and the sun that have gone through the orange blossoms. The orange tree that has taken several months to bring this wonder to you. Put a section in your mouth, close your mouth mindfully, and with mindfulness feel the juice coming out of the orange. Taste the sweetness. Do you have the time to do so? If you think you don’t have time to eat an orange like this, what are you using that time for? Are you using your time to worry or using your time to live?

Spiritual practice is not just sitting and meditating. Practice is looking, thinking, touching, drinking, eating, and talking. Every act, every breath, and every step can be practice and can help us to become more ourselves.

The quality of our practice depends on its energy of mindfulness and concentration. I define mindfulness as the practice of being fully present and alive, body and mind united. Mindfulness is the energy that helps us to know what is going on in the present moment. I drink water and I know that I am drinking the water. Drinking the water is what is happening.
