A commission made up of some big names, though not really any names of addiction or drug researchers I noticed, just released a report that’s making a lot of noise throughout every news channel including NPR (see here, and here for stories) and others (see CNN). They want the debate about the current state of drug regulation expanded, and since I’ve written on the issue before, I figured it’s time for another stab at this.

A study published in Addictive Behaviors showed that thinking actively about quitting smoking cigarettes allows people to smoke less!!!
In the experiment, participants from one group of smokers were asked to think about reasons to quit smoking and write them down on a piece of paper. Participants from a second group of smokers were asked to read pre-written anti-smoking arguments.
Both groups of participants were then asked to wait up to 30 minutes while the experimenter prepared a task unrelated to the actual experiment. Individuals who generated their own arguments against smoking abstained from smoking cigarettes longer than those who read pre-written anti-smoking arguments.
The results of this experiment suggest that self-generated information has a greater influence on smoking behavior (at least in the short-term) than information that is simply read.
Many anti-smoking campaigns try to “educate” people out of smoking cigarettes. They provide a great deal of information on the potential health hazards of smoking and try to convince smokers to quit. This approach can be dangerous as smokers might feel as though they are being attacked and react defensively. The truth is, many smokers already understand the consequences of tobacco use. If anti-smoking campaigns could find a way to develop personal beliefs against smoking, smokers might have an easier time not lighting up.

Drugs: Bath salts, menthol cigarettes, and Charlie Sheen
PhoenixHouseOC-Geoff Henderson, the senior director for Phoenix House, the country’s largest nonprofit provider of substance use disorder and behavioral health treatment services recently attended the hearing in Los Angeles to ban bath salts. He gave his interpretation on the bath salts issue, emphasizing that in our world today we have an increasing amount of access to a variety of substances and that new things are continuously emerging that individuals might try. For more of Henderson’s thoughts check out his blog.
Star-Telegram– A study has been conducted which found that adding menthol to cigarettes may increase the likelihood of addiction. Menthol cigarettes are considered to be so dangerous because they have a cooling and anesthetic effect which may get more adolescents to smoke. There is a debate to see if menthol cigarettes should be banned. Right now they make up 30 percent of the cigarette market and are favored by 80 percent of African American smokers.
Psychology Today– Charlie Sheen is the latest celebrity that is dealing with drug addiction. He has previously mentioned that he did not want to go to rehab because he thought that he could clean himself up and expressed his disdain for everything 12-steps. A lot of people thought that this was ridiculous but here is an article in which Dr. Stanton Peele agrees with Charlie. Dr. Peele believes that a person can be fixed if they are being forced to do so and that I why he agrees with Charlie Sheen that only he can overcome his addiction on his own. Read this article to get a different opinion on addiction treatment. You can check out this article for Dr. Jaffe’s take on the same issue.
Alcohol-The youth and DUI’s
Medical News Today– A new study by (SAMHSA) found that 5.9 percent of adolescents aged 12 to 14 drank alcohol and about 317,000 of them received this alcohol from their parents or got it at home. This can dangerous because being exposed to alcohol at an early age can expose at-risk children to an increased risk of alcohol abuse and addiction later on in their lives. Parents should be educated about such risk factors and about limiting access and increasing education for at risk youth.
Contra Coast Times– A man who was arrested for driving under the influence was found guilty of a DUI after showing up to his pretrial hearing drunk. The man ran his vehicle off the road into a barbed wire fence back in 2010. At the time of the arrest his blood alcohol level was more than four times the legal limit.
The Daily Beast– Can there be such a thing as anxiety addiction? Some individuals think so. A study was conducted that found that during demanding and stressful circumstances our bodies cultivate and thrive on anxiety. The study found that during a stressful circumstance is was possible that some individuals use anxiety to boost cognitive performance while others are comforted by anxiety. Whether this should be called addiction, I’m not sure, but the idea of anxiety as rewarding is interesting.
If you’ve been reading A3 for a while, you know that we’re big supporters of scientific progress in addiction treatment. While it may be true that addicts need to want recovery in order to truly turn their lives around, the choice is hardly ever that simple and if we can tip the balance in the favor of treatment, or a better way of life, I say let’s go for it. When it comes to genetics and addiction, I’ve normally talked only about the fact that a person’s genetic code may predispose them to addiction or to other related conditions (like depression, anxiety, and so on). Aside from a single mention of pharmacogenomics, I don’t think I’ve spoke much about the way genetics can help us tailor addiction treatment to individual needs. We’re about to fix that.
Replacement therapies and quitting smoking
You’ve heard of nicotine patches and gums, right? In the research community, those are all known as Nicotine Replacement (NR) therapy and they’ve proven to be some of the most helpful tools for those who are quitting smoking. By allowing smokers to still get the nicotine their body craves (even though there are thousands of other chemicals in cigarettes that likely make them even more satisfying) without having to light up, these NR methods let cigarette addicts get their NIC fix while slowly lowering their dose and getting away from the habit of putting a cigarette in their mouth. Like methadone, buprenorphine, and other replacement therapies, the idea is to move addicts one step away from the actual addictive behavior and allowing them to begin adopting a healthier way of living. Replacement therapies are very successful, even if some people hate the idea of giving drugs to drug addicts, and nicotine replacement works well by itself for some people (though only about 20%).
But when it comes to nicotine, like with many other drugs, different people metabolize the stuff at different rates. The individual variability in the internal processing of nicotine greatly affects how many cigarettes individuals smoke and also the probability that they will become addicted to tobacco (people who metabolize nicotine more quickly smoke more and are more likely to become addicted to smoking). Fast metabolizers are also half as likely to be able to use nicotine replacement alone to quit smoking (1). However, when you put all of the addiction research together, it becomes pretty obvious that the same variability in nicotine metabolism can also help us determine the best course of treatment for tobacco addiction.
Metabolism, treatment, and the best way to quit smoking
Fortunately for smokers, the only research finding in this area hasn’t been that slow metabolizes have a much better chance of quitting smoking with nicotine replacement therapy. The same group of addiction researchers (led by Caryn Lerman of University of Pennsylvania), also found that buporopion, the smoking cessation medication everyone knows as Zyban (and the antidepressant called Wellbutrin), could help those fast metabolizers catch up with the slow metabolizers when it came to quitting (see the figure on the left taken from the actual study – you see that the dark bars, who are the bupropion patients, do as well as the white bars regardless of their metabolism rate, which is on the bottom). The researchers found that while slow matabolizers of nicotine did much better with simple smoking cessation therapy and fast metabolizers did very poorly (30% versus 10% quit respectively in each of the groups), adding bupropion made all groups look essentially the same (2). The moral? While those slow metabolizers don’t really get much of a benefit from using bupropion since they do pretty well with talk therapy or nicotine replacement alone, the fast metabolizers really need it to even their chances of quitting – and once they get bupropion, they do pretty well!
Genetics and addiction treatment – is this just the beginning?
Hopefully you’re now convinced that genetics can really help us determine what treatment course will best suit a specific person over another. There’s little question that this sort of approach is in its infancy, and you certainly can’t go to a doctor right now and get your metabolism rate for a drug analyzed (unless you’re part of a research study), but this sort of work shows great promise in improving the outcomes of addiction treatment. When you look back at that original paragraph, and the quite common thinking that addicts need to WANT to be better – I would argue that those fast metabolizers probably wanted to quit smoking as much as anyone else in the study, and their physical makeup just made it that much more difficult for them. I think that if you look at the science of addiction closely, you’ll find that this supposed lack-of-motivation is sometimes more of a myth than a reality. Many addicts want to get better, they want to stop behaving in ways that specifically mess up their lives but they just find it incredibly difficult. My hope is that this is where science can truly make a difference, by making it just a little bit easier…
Hopefully one day we’ll be able to specifically adjust addiction treatment programs according to individual patients’ needs, including the use of medications, specific behavioral treatments, and more.
