Research gives insight into why some people develop addiction Researchers at the University of Cambridge have identified abnormal brain structures in the frontal lobe of cocaine users' brains which are linked to their compulsive cocaine-using behavior. Their findings were published today, 21 June, in the journal Brain. Led by Dr Karen Ersche, the Cambridge researchers scanned the brains of 120 people, half of whom had a dependence on cocaine. They found that the cocaine users had widespread...

But recent drug use diminishes response to drug images and other emotional stimuli over time Scientists at the U.S. Department of Energy's Brookhaven National Laboratory and Stony Brook University (SBU) have conducted the most comprehensive study to date of how cocaine users respond to drug-related and other emotional stimuli, making use of comparisons with a matched control group and exploring the effects of recent cocaine use and abstinence. The findings appear in a paper published online...

In a study published online March 2 in the journal Addiction, researchers in the United States have discovered that accidental overdose deaths involving cocaine rise when the average weekly ambient temperature passes 24 degrees Celsius (75 degrees Fahrenheit). Using mortality data from New York City's Office of the Chief Medical Examiner for 1990 through 2006, and temperature data from the National Oceanic and Atmospheric Association, researchers found that accidental overdose deaths that...

Cocaine use can have toxic effects on brain cells (neurons) that produce dopamine, say experts at Baylor College of Medicine in Houston in a report that appears today in the journal Psychiatry Research.  Using brain tissue acquired after the subjects died, researchers microscopically compared the number of dopamine cells in the brains of 10 cocaine users to those in the brains of nine people matched for age who did not use the drug. They found significantly fewer dopamine cells, 16...

A team of scientists believe they have discovered a part of the brain which responds to cocaine use. The results of their research may further explain why some users make cocaine use a habit while others become social users.Using brain scans, Hugh Garavan, a cognitive neuroscientist at Trinity College Dublin, and his colleagues studied cocaine users while they performed simple computer tasks. During the tests, they were able to locate areas of the pre-frontal cortex where increased activity...

High incidence of aneurysms found in users, study finds HealthDay News -- Cocaine users seem to have an unusually high incidence of coronary artery aneurysms, weakened areas of heart blood vessels that raise the risk of heart attacks, new research finds. The study included 191 men and women in their 40s who had angiography, an X-ray of blood vessels, because of known or suspected heart disease. Aneurysms were found in 34 of the 112 persons who reported using cocaine and only six of 91...
