Random Notes from the College on Problems of Drug Dependence

Opening day addresses at the annual meeting.

(These are notes on research in progress, not findings written in stone).

--NIDA director Nora Volkow talked up buspirone (Buspar) as a treatment for cocaine addiction, and referred to favorable results on buspirone for cocaine self-administration in monkeys in a large clinical trial. Also, different vaccine strategies are in the works, including different pharmacological approaches to blocking specific dopamine transporter molecules.

--Edward Sellers of DL Global Partners, a drug research consulting firm, emphasized the importance of enzyme variations in smoking. Variants of the CYP2A6 enzyme of metabolization allow us to identify “slow metabolizers” who respond well to placebo or nicotine patch therapy, and other smokers who don’t.

--Sherry McKee of the Yale University School of Medicine reminded everyone that cigarette smokers—even very light smoking “chippers”— are far more likely to have concurrent drinking problems than non-smokers. Smoking helps drinkers drink more and longer. To demonstrate such “potentiated reinforcement,” she showed a delightful video of her child eating cookies, then craving a glass of milk, then succumbing to another round of cookie consumption…

--Jack Henningfield of Pinney Associates, and former NIDA research chief, said that the reason the National Institute on Alcohol Abuse and Alcoholism (NIAAA) became an agency focused on “one molecule” is because Senator Harold Hughes, recovering alcoholic from Iowa, and Bill W., co-founder of Alcoholics Anonymous, wanted it that way.

--David Penetar of Harvard Medical School and McLean Hospital added more evidence of the link between alcohol and cigarettes, noting that “90 per cent of smokers drink,” and that smokers are three times as likely to be alcoholics than non-smokers. He pointed to research documenting a disturbing “increased desire to drink” when wearing a nicotine patch. With a patch, subjects reported feeling the effects of alcohol sooner and longer.

Bath Salts and the College on Problems of Drug Dependence

CPDD holds annual meeting.

I’ll be out of the office for a few days, attending the annual meeting of the College on Problems of Drug Dependence (CPDD), the oldest group in the United States dedicated to addressing problems of drug addiction. The organization functions as an independent body, and is affiliated with other scientific and professional societies involved in the study of drug dependence and abuse. The meeting dovetails with the 2012 NIDA International Forum. A broad selection of the nation’s top drug and addiction researchers will be there, along with Nora Volkow, Director of the National Institute of Drug Abuse (NIDA), and Drug Czar Gil Kerlikowske, director of the Office of National Drug Control Policy.

 I’m pleased to be the recipient of the organization’s 2012 CPDD/NIDA Media Award, which is given each year for “contributions through the media that have enhanced the public understanding of scientific issues concerning drug use disorders.” That’s pretty nice of them, and you can find an interview I did for their CPDD blog HERE.

While in attendance, your faithful correspondent will be attending what looks to be a massively interesting panel discussion called “A Stimulating Soak in “Bath Salts”: Investigating Cathinone Derivative Drugs.” Look for a blog post on that one.

I’m also planning to attend a symposium on “Exercise as a Treatment for Drug Dependence in Humans,” and plan to report back on that topic as well.
