Addiction Specialist Kicks Off A3 Academy in L.A.


Filling the void between “doing nothing and formal treatment.”

Good news for recovering addicts and addiction experts in Los Angeles: Dr. Adi Jaffe, a well-known addiction psychologist from UCLA and a longtime friend of Addiction Inbox, is kicking off a new venture: the A3 Academy.

 Dr. Jaffe, who runs the All About Addiction website, and writes a column for Psychology Today, knows whereof he speaks, having spent 8 years as a meth addict and drug dealer in a former lifetime. “The A3 Academy is specifically formulated to fill the void between doing nothing about addiction and formal addiction treatment,” Dr. Jaffe said. The inaugural academy will be held on Tuesday, September 6th, in West Los Angeles (2001 Barrington Ave.) at 6:00 PM, and is intended to become a weekly event. Information, tickets, and details of online participation are available HERE. Or you can email for information at academy@allaboutaddiction.com.

“If it has to do with addiction,” we’ll probably cover it,” Dr. Jaffe said. He plans to integrate “informational sessions, process groups, life planning, mindfulness, nutrition, and expert consultation with leading addiction experts from the Los Angeles area and beyond.”

Dr. Adi told Addiction Inbox that “local LA people can attend the event, and others can stream and watch, and the cost is purposefully low. It's going to be an educational/empowerment sort of thing that will adapt to the needs of the specific group attending.”

Judging by his blog postings at All About Addiction, Dr. Jaffe brings a wealth of information and experience to the task—as well as being an accomplished public speaker. “I’ve learned a lot about the genetic, behavioral, and environmental influences on addiction and drug-abuse,” he says. “Whatever you’re comfortable calling addiction, there’s no doubt that it’s having a great, negative, impact on those it affects. More than 500,000 deaths and a burden of more than $500 million dollars are attributed to substance abuse every year in the United States alone. I think it's time we get real about the problem and stop using stigma and misinformation to hide behind.”

Is Shoplifting the Opiate of the Masses?


Another look at "behavioral addictions" and the DSM-V.

The DSM-V, when it debuts it 2012, is set to replace the category of “Substance-Related Disorders” with a new category entitled "Addiction and Related Disorders."  Gambling is the only behavioral addiction currently recommended for inclusion, but some experts have set their sights on shoplifting—an activity that is even more difficult to picture as a legitimate addiction than gambling. Or is it?

Long before gambling was widely looked upon as an addictive disorder, compulsive shoplifting already had a name: kleptomania. The National Association for Shoplifting Prevention claims that about 9-10% of the population show a “lifetime prevalence” for shoplifting. This is remarkably similar to the percentages commonly bandied about for alcoholics, drug addicts, unipolar depressives,  compulsive gamblers, and compulsive overeaters.

A recent University of Florida survey pegged shoplifting losses, or “shrink,” in 2009 at more $11 billion annually. Plato, in The Republic, wanted to know whether thieves are made or born. It’s a good question. Curiously, the stealing doesn’t seem to be about money: The most recent study measuring income and shoplifting shows that Americans with incomes over $70,000 shoplift 30% more more than their fellow citizens earning less than $20,000 a year. And the actual items stolen by compulsive shoplifters often seem nonsensical, or even surreal. As director John Waters said of Pink Flamingos’ star and compulsive shoplifter Divine: “I saw him walk out of a store once with a chain saw and a TV.”

There is a definite “rush” to the act of stealing, writes Rachel Shteir in The Steal, her informative book about shoplifting. One shoplifter said it was equal to drugs but only lasted a few minutes—“And you’re back to yourself again. In your mind, you think, It was all for a stupid blouse, or stupid soap. For this, I risked everything.” Another source quoted in the book says, “I shoplifted every day, like someone with a drug addiction.”  Seconds before another women is arrested, she quizzes herself: “All she needs in the world is one crummy formal dress so why is there a blue silk jacket, one that she doesn’t particularly like, in her camera bag?” And a shoplifting Lee Grant says in the movie Detective Story: “I didn’t need it. I didn’t even like it.” The objects seem to lose their intrinsic value once they have been stolen, and the shoplifter must get high again with another theft.

If, as some neurobiological researchers insist, addictive disorders are not independent disorders, but outward manifestations of an underlying disease pathology called addiction syndrome, then the definition might be stretched to include gambling, shoplifting, and certain other “activity-based expressions of addiction.” Sometimes the alcoholic, the drug addict, the depressive, the compulsive gambler, and the obsessive overeater are all one and the same person. And drug addicts show a remarkably ability to substitute one drug for another. Perhaps a recovering cocaine addict might hope to assuage that sense of craving, of inchoate need, through excessive gambling. Or a shoplifter might use alcohol as a means of dampening the impulse to steal compulsively. While we don’t use the term kleptomania anymore, “shoplifting crops up as a symptom of many types of mental illnesses—bipolar disorders and anxiety disorders as well as substance abuse, eating disorders, and depression,” writes Shteir. Compulsive shoplifting, Shteir concludes, is “as difficult to stamp out as oil spills or alcoholism.”

For some, shoplifting brings a rush “similar to a cocaine or heroin high,” according to psychiatist Jon Grant at the University of Minnesota School of Medicine. To find out just how similar, psychiatrists there tried treating shoplifters with naltrexone, a drug that blocks opioid receptors and is used to treat alcoholism and heroin addiction. In 2009, in an article for the April issue of Biological Psychiatry, Grant and colleagues at the University of Minnesota School of Medicine recorded the results of their work with 25 kleptomaniacs, most of them women. All of the participants had been arrested for shoplifting at least once, and spent at least one hour per week stealing. The 8-week study is believed to be the first placebo-controlled trial of a drug for the treatment of shoplifting. In the April 10 issue of Science, Grant said that “Two-thirds of those on naltrexone had complete remission of their symptoms.”

7 Myths the Alcohol Industry Wants You to Believe


Staying on message in the liquor biz. 

“Our national drug is alcohol,” wrote William S. Burroughs. “We tend to regard the use of any other drug with special horror.” This emotional loophole in the psyche has been skillfully manipulated by the alcohol and tobacco industries ever since modern advertising was invented.

 Recently, the European Alcohol Policy Alliance, known as EuroCare, put together a brochure addressing the common messages the liquor industry attempts to drive home through its heavy spending on advertising. The messages are not just designed to sell product, but also to influence alcohol policy at the political level as well. (Eurocare is a network of more than 50 voluntary non-governmental organizations working on the prevention and reduction of alcohol-related harm in 20 European countries.) According to the group, the “industry”—the alcohol and tobacco companies—“has traditionally worked closely together, sharing information and concerns about regulation. They have used similar arguments to defend their products in order to prevent or delay restrictions being placed on them (Bond, et al. 2010).”

EuroCare offers this introduction: “The intention of this brochure is to inform professionals about the attempts made by the alcohol industry to influence alcohol policy globally and to subsequently arm them against the industry’s methods to prevent effective policies from being made…. For politicians and health experts it is important that they reveal to the public the subversive messaging of the alcohol industry and do not fall prey to the industry’s half-truths—or worse—outright lies.”

Message 1: Consuming alcohol is normal, common, healthy, and very responsible.

Explanation: To bring this message home, alcohol advertisements nearly always associate alcohol consumption with health, sportsmanship, physical beauty, romanticism, having friends and leisure activities.

I note here that it’s left to the social service agencies and non-profits to attempt to convey the opposite side of the coin: a dramatically heightened risk for health problems, traffic fatalities, domestic violence, loss of job, loss of marriage, suicide—you name it.

Message 2: The damage done by alcohol is caused by a small group of deviants who cannot handle alcohol.

Explanation: Indeed, the message of the industry is that ordinary citizens drink responsibly and that ‘bad’ citizens drink irresponsibly and are the cause of any and all problems associated with high alcohol consumption.

This one is insidious and unscientific. There is no evidence that alcoholics are “bad people,” or simply unwilling to stop engaging in bad behavior. For the industry, irresponsible drinkers are a major revenue source—the dream customer— even though alcohol manufacturers continue to insist that their advertising is primarily about driving home the message of responsible alcohol consumption and brand choice.

Message 3: Normal adult non-drinkers do not, in fact, exist.

Explanation: Only children under 16 years of age, pregnant women and motorists are recognized by the industry as non-drinkers.

My personal favorite, this one. The existence of non-drinkers is seen by the industry as a threat. Accordingly, they have subtly reinforced the message that moderate drinking is not only normal, but also good for you. Never mind that the real profits come from excessive drinking and pricing strategies that encourage it. Estimates vary, but recent studies  at UCLA show that “the top 5% of drinkers account for 42%of the nation’s total alcohol consumption.” If 5% of all drinkers account for nearly half of total alcohol sales, it would be folly for the alcohol industry to get serious about encouraging moderation. It’s not too far off the mark to say that the alcohol industry’s quarterly statements hinge on the success they have in encouraging alcoholics to believe that everything’s okay, everybody drinks that way. The message becomes clearer: Drinking is mandatory—unless you’re a deviant.

Message 4: Ignore the fact that alcohol is a harmful and addictive chemical substance (ethanol) for the body.

Explanation: The industry does not draw attention to the fact that alcohol (ethanol) is a detrimental, toxic, carcinogenic and addictive substance that is foreign to the body.

Naturally, pointing out the neuroscientific parallels between alcoholism and heroin addiction is not part of the message. Alcohol is a hard drug—ask any addiction expert. Alcoholism can kill you quick. But so far, the labeling mania that struck opponents of Big Tobacco has not played out in a major way in the battle against deceptive alcohol advertising.

Message 5: Alcohol problems can only be solved when all parties work together.

Explanation: Good, effective policies to combat alcohol consumption would require a higher excise-duty, no marketing or sponsoring, an increase in the drinking age to 18, a prohibition of the illegitimate sale of alcohol, and an increase, through a campaign, in the public’s awareness of the damages that alcohol can cause (Babor et al, 2010; WHO, 2009).

Obviously, these bullet points are not high on the alcohol industry’s agenda.

Message 6: "Alcohol marketing is not harmful. It is simply intended to assist the consumer in selecting a certain product or brand."

Explanation: Meanwhile, research has indisputably demonstrated that alcohol advertisements are both attractive to young people and stimulate their drinking behavior (Anderson et al., 2009: Science Group of the Alcohol and Health Forum; 2009). Yet the industry continues to flatly and publicly deny that advertising stimulates alcohol consumption (Bond et al; 2009).

Stuffed with attractive young people meeting and mating over alcohol, it seems fair to suggest that alcohol ads had better stimulate increased drinking, i.e., a boost in quarterly sales, or else the industry is wasting a lot of money fighting over pieces of a pie that isn’t getting any bigger. These days, slow growth is no growth.


Message 7: “Education about responsible use is the best method to protect society from alcohol problems.”

Explanation: Effective measures such as a higher alcohol excise-duty, establishing minimum prices, higher age limits and advertisement restrictions can reduce alcohol related harm and will therefore decrease the profits of the industry (Babor, 2003; Babor, 2010). The industry therefore does its best to persuade governments, politicians, and policy makers that the above mentioned measures would have no effect, are only symbolic in nature or are illegitimate.

A truly great dodge, because the strategy being advertised sounds so imminently sensible. Who could be against the promotion of responsible alcohol use? Irresponsible zealots and deviants, that’s who. Why should all of us happy drinkers be made to suffer for the sins of a few rotten apples?

Indeed, all of the messages, overtly or covertly, send the same signal: You should drink more. It’s good for you.

What Does Harm Reduction Mean?


A rift in the addiction treatment community over abstinence.

What is harm reduction? How does it differ from the approaches traditionally associated with drug recovery and rehab?

Originally, I became interested in harm reduction because its advocates were highlighting the folly of prison terms over treatment for drug addicts—a sentiment with which I wholeheartedly agree. Also, the various harm reduction organizations worldwide were fastened tenaciously to the issue of clean needle exchanges as a means of reducing HIV transmission—another approach I heartily support. And at its core, harm reduction has always been about reducing the number of deaths by drug overdose. At its essence, harm reduction is sensible and necessary, given the failures of the drug war, and the inability to make a significant dent in addiction statistics by traditional socioeconomic approaches.

Harm reduction, as formally defined by Harm Reduction International, concerns itself with “policies, programs and practices that aim primarily to reduce the adverse health, social and economic consequences of the use of legal and illegal psychoactive drugs without necessarily reducing drug consumption. Harm reduction benefits people who use drugs, their families, and the community.” It’s a hopeful mission statement. But reducing harm without necessarily reducing drug consumption? What does that mean, exactly?

Lately, activists in the harm reduction movement have been leaning hard on the notion that abstinence is just so much humbug; an archaic admonition that need not be automatically imposed on addicts. Who said addicts have to become abstinent for the rest of their lives? Are we forever hostage to the religious zealotry of the Cambridge Group and it’s successor, Alcoholics Anonymous? If an alcoholic drinks one drink less today than yesterday, or a junkie shoots up a bit less junk today than yesterday, that is harm reduction in action.

But now that harm reduction has become intimately associated with the abstinence debate, egged on by activists like Stanton Peele and Jack Trimpey, the ground underneath the movement has shifted. Many harm reductionists are becoming wary, and sometimes completely hostile, to the notion of addiction as a disease syndrome with a distinct, lifelong, and incurable timeline beyond the reach of notions like “Rational” or “Smart” recovery. “Your best thinking got you here,” AA likes to say, reminding alcoholics that “being smart” or feeling full of “will power” often have less to do with recovery than one might suppose.

But in order to free themselves of the need for abstinence, extreme harm reductionists often deny that addiction is in any meaningful way a medical disorder. This has created a rift in the treatment community, and complicated the mission of recovery programs based on abstinence. Kenneth Anderson, a harm reduction advocate and the author of How to Change Your Drinking, framed it this way for me in an email exchange: “The more alcohol related problems you have, the more you need to practice harm reduction by planning safe drinking strategies, until you resolve your alcohol related problems by quitting or developing a non-problematic drinking pattern.” Like many harm reductionists, Anderson is no fan of Alcoholics Anonymous. One of the book’s sections is headed: “Everything You Always Wanted to Know About Alcohol—But you got told to go to AA and not ask.”

Anderson said that the National Institute on Alcohol Abuse and Alcoholism (NIAAA) “tells us that about half of people who overcome alcohol dependence do so by quitting, the other half overcome it by cutting back.” If even the nation’s premier scientific agency for researching alcoholism doesn’t seem so sure about whether alcoholics need to strive for abstinence, why should abstinence be a stated goal at the outset of treatment at all? Said Anderson: "When abstinence is forced on people against their will, it often backfires and leads to more drug or alcohol use."
 
A few weeks ago, on Denise Krochta’s excellent podcast, Addicted to Addicts, I suggested that part of the argument over abstinence vs. controlled drinking stemmed from a confused bundling of “problem drinkers” and “alcoholics”—a move that the National Institute on Alcohol Abuse and Alcoholism, whose very name is a testimony to the institute’s fundamental ambivalence, has been championing lately. This has helped harm reductionists center the battle precisely where the definitions are fuzziest: at the point on the spectrum where “problem drinking” becomes “alcoholism.” Nonetheless, by focusing on this imprecise edge, harm reductionists make a legitimate point: Culture and environment are major influences on the course of heavy drinking.

“I do not use the word alcoholism [in the book], because it has no scientific definition in the current day and is not found in the DSM IV” Anderson told me. “Although there is some heritability of alcohol dependence, it is a great error to overlook the importance of environmental factors. Alcohol dependence is not located on a single gene--currently there are dozens of genes implicated in alcohol dependence.” And he’s right. These are legitimate caveats that apply to many of the disease models of addiction now at play in the scientific community.

The counter-argument here is that genuine alcoholics do not have, and cannot develop, a “non-problematic drinking pattern,” any more than a serious diabetic is likely to develop a non-problematic sugar doughnut strategy. What alcoholic hasn’t tried controlled drinking? Again and again? And failed? Where are the legions of former drunk-tank alcoholics who have rationally transformed themselves into social drinkers?

These are some of the terms of the current debate in the addiction recovery community. But we do a disservice by concentrating solely on points of departure. The harm reduction movement, at street level, has some very sound contributions to make regarding addiction and public policy. Anderson, in his book, drives home the overlooked but essential point that there is no one-size-fits-all treatment for destructive drinking:
  • “Harm reduction never forces people to change in ways which they do not choose for themselves.”
  • “Harm reduction recognizes that each of us is a unique human being different from all others.”
  • “Harm reduction recognizes the need for ‘different strokes for different folks.’”
  • “Harm reduction supports every positive change.”
I fervently hope that 12-Step Groups and Harm Reduction Groups can work their way toward a rapprochement. And so does Kenneth Anderson. But what stands in the way of this is, I fear, is the disease model of addiction—and medical addiction researchers aren’t likely to turn their backs on that premise any time soon. Still, we cannot say what future research will reveal. And I agree with harm reductionists that the best attitude we can bring to the subject of addiction and recovery is open-mindedness, and a willingness to treat each case as unique, in order to forestall “metabolic chauvinism.”

Common Field Test for Marijuana is Unreliable, Critics Say


A 75-year old pot assay is due for an update.

We’ve all seen it on cop shows: The little plastic bag, the officer breaking the seal on a small pipette and inserting a bit of marijuana, then a firm shake, and voila, the liquid in the test satchel turns purple: Guilty.

Here’s an interesting twist they don’t tell you about: The so-called Duquenois-Levine test—the dominant method for field-testing marijuana since 1930—is considered by many to be wildly inaccurate, and frequently doesn’t hold up in court. One U.S. Superior Court judge referred to the test as “pseudo-scientific.”

The test itself works fine. The problem is that, in addition to identifying marijuana or hashish, the Duquenois-Levine, or D-L, frequently reads positive for tea, nutmeg, sage, and dozens of other chemicals—including resorcinols, a family of over-the-counter medicines, which, according to John Kelly at AlterNet, includes Sucrets throat lozenges. This does matter, because in New York, Washington, D.C., and elsewhere, inner-city minority kids are getting busted for pot in record numbers. Lacking a reliable test protocol, marijuana is whatever the officer says it is. In a classic case that continues to bedevil the testing industry, a middle-aged woman was busted for marijuana while bird watching. A “leafy substance” turned purple on the Duquenois-Levine (D-L) test, and the woman was arrested. The material turned out to be sage, sweetgrass, and lavender, and the woman was engaging in a Native American purifying ritual using a smudge, a concept with which the arresting officers were unfamiliar.

So, when push comes to shove, a positive D-L rarely establishes the presence of marijuana beyond a reasonable doubt, without further confirmatory testing. For at least 20 years now, a visual inspection and a NarcoPouch, as the D-L field test is called, were enough to bring on the felony charges. State courts have squabbled over the matter, but state legislatures have been reluctant to intervene, in large part because sending samples to a lab for confirmatory testing is prohibitively expensive, particularly when the busts are small. The D-L test saves money.

According to the official drug policy of the United Nations, a positive marijuana ID requires gas chromatography/mass spectrometry analysis. And even this far more sophisticated test has angered courts in Washington and Colorado, the UK Guardian reports, “because the DEA doesn’t have standard lab protocols to govern its use.” In part, the judges are furious because plea-bargaining depends upon valid drug possession evidence. So, the officers themselves, when it comes to testifying in court, become de facto expert witnesses, able to identify illegal drugs on sight. Ah, those were the days. But now, cannabis-based products come in a bewildering variety of sizes, shapes, colors, smells, and chemical compositions.

But c’mon, if it looks like bud and it smells like bud… except that the research shows there are 120 terpenoid-type compounds involved in the odor of marijuana. No two varieties smell exactly alike. There is no characteristic marijuana smell—there are hundreds of characteristic marijuana smells. Nonetheless, in 2009 the National Academy of Sciences called the testing of controlled substances “a mature forensic science discipline,” according to AlterNet.

In a 2008 article for the Texas Tech Law Review, Frederic Whitehurst, Executive Director for the Forensic Justice Project and formerly with the FBI, concluded: “We are arresting vast numbers of citizens for possession of a substance that we cannot identify by utilizing the forensic protocol that is presently in use in most crime labs in the United States.” In another section of the article, Whitehurst asks: “Why is this protocol still being utilized to decide whether human beings should be confined to cages and at times, to death chambers?” And as Stewart J. Lawrence and John Kelly write in the Guardian, “using manifestly flawed drug identification tests to charge defendants, or pressure them to plead guilty, is hard to square with a defendant’s right to due process.”

The Original Magic Bus: A Preview


Ken Kesey and His Merry Band of Pranksters Search for a Cool Place

"In 1964, Ken Kesey, the famed author of "One Flew Over the Cuckoo's Nest," set off on a legendary, LSD-fuelled cross-country road trip to the New York World's Fair. He was joined by "The Merry Band of Pranksters," a renegade group of counterculture truth-seekers, including Neal Cassady, the American icon immortalized in Kerouac's "On the Road," and the driver and painter of the psychedelic Magic Bus. Kesey and the Pranksters intended to make a documentary about their trip, shooting footage on 16MM, but the film was never finished and the footage has remained virtually unseen. With Magic Trip, Oscar-winning director Alex Gibney and Alison Ellwood were given unprecedented access to this raw footage by the Kesey family. They worked with the Film Foundation, HISTORY and the UCLA Film Archives to restore over 100 hours of film and audiotape, and have shaped an invaluable document of this extraordinary piece of American history."

Cigarette Sadness


The chemistry of sorrow during nicotine withdrawal.

When you smoke a cigarette, nicotine pops into acetylcholine receptors in the brain, the adrenal glands, and the skeletal muscles, and you get a nicotine rush. Just like alcohol, a cigarette alters the transmission of several important chemical messengers in the brain. “These are not trivial responses,” said Professor Ovide Pomerleau of the University of Michigan Medical School. “It’s like lighting a match in a gasoline factory.”

Experiments at NIDA’s Addiction Research Center in Baltimore have confirmed that nicotine withdrawal not only makes people irritable, but also impairs intellectual This post was chosen as an Editor's Selection for ResearchBlogging.orgperformance. Logical reasoning and rapid decision-making both suffer during nicotine withdrawal. Acetylcholine appears to enhance memory, which may help explain a common lament voiced by many smokers during early withdrawal. As summarized by one ex-smoker, “I cannot think, cannot remember, cannot concentrate.”

But there is another, less widely discussed aspect of nicotine withdrawal: profound sadness. Profound enough, in many cases, to be diagnosed as clinical unipolar depression.

 Of course, people detoxing from addictive drugs like nicotine are rarely known to be happy campers. But quitting smoking, for all its other withdrawal effects, reliably evokes a sense of acute nostalgia, like saying goodbye to a lifelong friend. The very act of abstinence produces sadness, joylessness, dysphoria, melancholia—all emotional states associated with unipolar depression.

Work undertaken by Dr. Alexander Glassman and his associates at the New York State Psychiatric Institute has nailed down an unexpectedly strong relationship between prior depression and cigarette smoking, and the findings have been confirmed in other work. This sheds important light on the question of why some smokers repeatedly fail to stop smoking, regardless of the method or the motivation.  The problem, as Glassman sees it, is “an associated vulnerability between affective [mood] disorders and nicotine.”

Now a group of Canadian researchers, working out of the Centre of Addiction and Mental Health (CAMH), and the Department of Psychiatry at the University of Toronto, believe they have isolated the specific neuronal mechanisms responsible for the profound sadness of the abstinent smoker.

Writing in the Archives of General Psychiatry, the investigators, who had access to what the CAMH proudly calls the only PET scanner in the world dedicated to mental health and addiction research, gave PET scans to 24 healthy smokers and 24 healthy non-smokers. Non-smokers were scanned once, while heavy and moderate cigarette smokers were scanned after smoking a cigarette, and also after a period of acute withdrawal. Earlier research of this kind had focused on nicotine’s effect on dopamine release. But Ingrid Bacher and her coworkers in Toronto were measuring MAO-A levels in the prefrontal and anterior cingulate regions, two areas known to be involved in “affect,” or emotional responses. When patients suffering from major depressive disorders get scanned, they tend to show elevated levels of MAO-A. The so-called MAO-A inhibitors Marplan, Nardil, Emsam, and Parnate are still in use as antidepressant medications. In general, the higher the levels of MAO-A, the lower the levels of various neurotransmitters crucial to pleasure and reward. A high level of MAO-A would suggest that the enzyme was significantly altering the activity of serotonin, dopamine, and norepinephrine in brain regions involved in mood.

The researchers found that smokers in withdrawal had 25-35% more MAO-A binding activity than non-smoking controls. “This finding may explain why heavy smokers are at high risk for clinical depression," says Dr. Anthony Phillips, Scientific Director of the Canadian Institutes of Health Research's (CIHR's) Institute of Neurosciences, Mental Health and Addiction, which funded this study.

Although researchers involved in these kinds of drug studies almost always claim that the work is likely to lead to new pharmacological therapies, the plain truth is that such immediate spinouts are rare. But in this case, it does seem like the study provides a clear incentive to investigate the clinical standing of MAO-A inhibitors as an adjunct therapy in stop-smoking programs. “Understanding sadness during cigarette withdrawal is important because this sad mood makes it hard for people to quit, especially in the first few days,” said Dr. Jeffrey Meyer, one of the study authors.

As one addiction researcher noted, an associated vulnerability to depression “isn’t going to cover everybody’s problem, and it doesn’t mean that if you give up smoking, you’re automatically going to plunge into a suicidal depression. However, for people who have some problems along those lines, giving up smoking definitely complicates their lives.”
