Stress-induced changes in brain circuitry linked to cocaine relapse
Stress-evoked changes in circuits that regulate serotonin in certain parts of the brain can precipitate a low mood and a relapse in cocaine-seeking, based on mouse studies published online this week in the Proceedings of the National Academy of Sciences. view more (2009-10-30)
Cocaine exposure during pregnancy leads to impulsivity in male, not female, monkeys
Adult male monkeys exposed to cocaine while in the womb have poor impulse control and may be more vulnerable to drug abuse than female monkeys, even a decade or more after the exposure, according to a new study by researchers at Wake Forest University School of Medicine. The findings could lead to a better understanding of human drug abuse. view more (2009-10-23)
Computer Model Shows Changes in Brain Mechanisms for Cocaine Addicts
About 2 million Americans currently use cocaine for its temporary side-effects of euphoria, which have contributed to making it one of the most dangerous and addictive drugs in the country. view more (2009-09-23)
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)
New study: Up to 90 percent of US paper money contains traces of cocaine
You probably have cocaine in your wallet, purse, or pocket. Sound unlikely or outrageous? Think again! In what researchers describe as the largest, most comprehensive analysis to date of cocaine contamination in banknotes, scientists are reporting that cocaine is present in up to 90 percent of paper money in the United States, particularly in... view more...

Cocaine and heroin harm placenta
Cocaine and heroin increase permeability of the placenta. Researchers writing in BioMed Central's open access journal Reproductive Biology and Endocrinology have shown that exposure to the drugs causes an increase in the passage of some chemicals into the fetus. view more (2009-06-11)
Brain-behavior disconnect in cocaine addiction
Parts of the brain involved in monitoring behaviors and emotions show different levels of activity in cocaine users relative to non-drug users, even when both groups perform equally well on a psychological test. view more (2009-05-26)
Cocaine: Perceived as a reward by the brain?
Cocaine is one of the oldest drugs known to humans, and its abuse has become widespread since the end of the 19th century. view more (2009-05-20)
Cocaine-linked genes enhance behavioral effects of addiction

BUSM researchers find prenatal cocaine exposure may compromise neurocognitive development
Researchers at Boston University School of Medicine (BUSM) have found that heavier intrauterine cocaine exposure (IUCE) is associated with mild compromise on selective areas of neurocognitive development during middle childhood. view more (2009-05-01)
Treating addiction by eliminating drug-associated memories
Addicts, even those who have been abstinent for long periods of time, are often still vulnerable to their own memories of prior drug use. For example, exposure to the same environment in which they commonly used drugs -- a contextual memory -- can increase their craving for the drug dramatically and can lead to relapse. view more (2009-04-23)
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)

Seven out of every ten drug addict men admit they consume drugs to increase their sexual pleasure
A study carried out at the University of Granada has analysed the connection between drug consumption and sexual performance by means of a survey of 120 drug addict characters. The work has revealed that, paradoxically, most of the men who consume drugs to lose their sexual inhibition use cocaine, a narcotic substance which incapacitates at sexual... view more...
