The first large-scale analysis of proteins in the brains of monkeys addicted to cocaine reveals new information on how long-term cocaine use changes the amount and activity of various proteins affecting brain function.The identified changes are more numerous and long-lasting than previously thought, which may provide a biological explanation for why cocaine addiction is so difficult to overcome, according to Scott E. Hemby, Ph.D. of Wake Forest University School of Medicine, senior author of...

New forms of synthetically sweetened cocaine has been discovered in California by federal drug agents who hope to stop its development before it becomes available to other parts of the nation. Drug agents said the new product was more sophisticated than previous forms that attempted to mix cocaine with powdered candy. The previous form was cut with extra flavoring, thus making it less potent, but the amount seized last week was full-strength, investigators say. Flavors included strawberry,...

Having a lower social standing increases the likelihood that a monkey faced with a stressful situation will choose cocaine over food, according to a study at Wake Forest University School of Medicine. More dominant monkeys undergoing the same stressful situation had fewer changes in brain activity in areas of the brain involved in stress and anxiety and were less likely to choose cocaine. Robert Warren Gould, a graduate student in the laboratory of Michael A. Nader, Ph.D., presented the study...

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...

Study in mice shows drug's effects extend beyond dopamine, brain's 'reward' chemical UPTON, NY - Many studies on cocaine addiction - and attempts to block its addictiveness - have focused on dopamine transporters, proteins that reabsorb the brain's "reward" chemical once its signal is sent. Since cocaine blocks dopamine transporters from doing their recycling job, it leaves the feel-good chemical around to keep sending the pleasure signal. Now a new study conducted at the U.S. Department of...

Titsworth said he was high on crack cocaine when he struck Sossaman about 16 times with the ax. Sossaman told a friend the day before the attack she was going to ask Titsworth to...

President Vicente Fox will not oppose the bill, passed by senators last week, presidential spokesman Ruben Aguilar told reporters, despite likely tensions with the United States. "The president is going to sign that law, there would be no objection," he said. "It appears to be...

By Katie Nguyen NAIROBI (Reuters) - A Kenyan judge postponed the destruction of a record 1.1 tonne cocaine haul for a week from Friday to give Western experts time to verify the cache, which diplomats fear may have been tampered with. "I allow the adjournment because the state is not ready for the destruction of the drugs," Chief Magistrate Aggrey Muchelule said, adding it would be destroyed next Friday. Police seized the haul -- worth an estimated $88 million and said at the time...
