Large family study pinpoints genetic linkage in drug addiction
Based on data obtained from one of the largest family sets of its kind, Yale School of Medicine researchers have identified a genetic linkage for dependence on drugs such as heroin, morphine and oxycontin. view more (2006-04-11)
Research elucidates mechanism by which gene expression may be altered in drug addiction
Dr. Judith A. Potashkin, Ph.D. and her colleagues at Rosalind Franklin University of Medicine and Science recently completed a study investigating one of the changes in gene expression that occurs when individuals take addictive drugs. view more (2007-09-05)
Ecstasy alone can kill--and numbers of deaths continue to rise.

Fluoxetine: antidepressant and a possible new drug for the treatment of obesity
The Department of Nutrition and Bromatology of the Faculty of Pharmacy of Gasteiz, University of the Basque Country, is studying the action mechanism of fluoxetine in genetically fattened rats (Zucker fa/fa). Due to fluoxetine, those rats eat 50 % less. Therefore, the bodies put on less weight and the size of different fat tissues is reduced.... view more... (2002-07-30)
Research reveals why some smokers become addicted with their first cigarette
New research from The University of Western Ontario reveals how the brain processes the 'rewarding' and addictive properties of nicotine, providing a better understanding of why some people seemingly become hooked with their first smoke. view more (2008-08-06)
Clubbers And Drugged Driving
New research carried out by the University of Surrey has revealed that clubbers who have taken illegal drugs could be in serious danger when driving home after a night out. The study suggests the effects of illicit drugs like ecstasy and cocaine during clubbing could dramatically impair the skills needed for driving. Concerns have been raised... view more...

A Molecular Basis for Cocaine Abuse: PLoS Biology Press Release
This Is Your Fly's Brain on Drugs Cocaine addiction wreaks profound changes on the brain, hijacking reward circuits and depressing inhibitory loops to the point that drug seeking and taking become central drivers of behavior. While mammalian models are useful for mapping out the neural complexity of these behaviors, insights into the molecular... view more... (2004-11-16)
UT Southwestern researchers discover brain's memory 'buffer' in single cells
Individual nerve cells in the front part of the brain can hold traces of memories on their own for as long as a minute and possibly longer, researchers at UT Southwestern Medical Center have found. view more (2009-01-26)

Misusing vitamin to foil drug test may be toxic; plus, it doesn't work
Taking excessive doses of a common vitamin in an attempt to defeat drug screening tests may send the user to the hospital—or worse. view more (2007-04-11)
Alcohol, not drugs, biggest health threat to clubbers
The biggest health threat to clubbers is not drugs, but alcohol, although drugs are fast catching up, reveals a study of the UK clubbing scene, reported in Emergency Medicine Journal. Club-owners and brewers should fund measures needed to reduce "the considerable healthcare and civic costs" of the activity, conclude the authors. Every... view more... (2002-11-01)
Sugar can be addictive, Princeton scientist says
A Princeton University scientist will present new evidence today demonstrating that sugar can be an addictive substance, wielding its power over the brains of lab animals in a manner similar to many drugs of abuse. view more (2008-12-10)
Smoking produces changes in human brain like those in animals using illicit drugs
New research shows for the first time that smoking produces long-lasting biochemical changes in the human brain similar to those changes previously seen in the brains of animals that used cocaine, heroin, and other illicit drugs. view more (2007-02-20)
Researchers explore long-term adolescent vulnerability to drugs
As part of efforts to understand drug abuse, Georgia State University researchers are finding that adolescent rats appear to be less vulnerable to the long-term effects of withdrawal and relapse in certain types of drug use than rats that take the drugs in adulthood. view more (2009-09-17)
Hair samples show babies can be exposed to 'crystal meth' while in the womb

Phasic firing of dopamine neurons is key to brain's prediction of rewards
Researchers are one step closer to understanding the neurobiology that allows people to successfully learn motivated behaviors by associating environmental cues with rewarding outcomes, according to a study published yesterday in the Proceedings of the National Academy of Sciences' online Early Edition. view more (2009-04-06)
New research identifies gene important for nicotine's effects on the brain
New research identifies an important gene that influences several aspects of nicotine-induced behaviors in the brain. The study, funded by National Institutes of Drug Abuse, was presented today at the American College of Neuropsychopharmacology's Annual Meeting. view more (2006-12-06)
