Connie K. Ho for RedOrbit.com Found in more than 400,000 emergency room visits and related to 5,000 overdose deaths a year in the United States, cocaine is a highly dangerous drug that can lead to death. Scientists at the Scripps Institute of Research decided to tackle this issue head on with a study that examines a solution that can be injected to reverse the effects of cocaine overdose in emergency situations. With the solution´s success in trials with mice, the researchers hope to...

When first exposed to cocaine, the adolescent brain launches a strong defensive reaction designed to minimize the drug's effects, Yale and other scientists have found. Now two new studies by a Yale team identify key genes that regulate this response and show that interfering with this reaction dramatically increases a mouse's sensitivity to cocaine. The findings may help explain why risk of drug abuse and addiction increase so dramatically when cocaine use begins during teenage years....

Research published by Cell Press in the January 12 issue of the journal Neuron provides fascinating insight into a newly discovered brain mechanism that limits the rewarding impact of cocaine. The study describes protective delayed mechanism that turns off the genes that support the development of addiction-related behaviors. The findings may lead to a better understanding of vulnerability to addiction and as well as new strategies for treatment. Drug addiction is associated with...

When a research team asked cocaine addicts to choose, hypothetically, between money now or cocaine of greater value later, "preference was almost exclusively for the money now," said Warren K., Bickel, professor in the Virginia Tech Carilion Research Institute, director of the Advanced Recovery Research Center, and professor of psychology in the College of Science at Virginia Tech. This result is significantly different from previous studies where a subject chooses between some money now or...

A common medication shown to hinder retrieval of memories associated with cocaine use in animal models New discoveries by researchers at the University of Wisconsin-Milwaukee (UWM) offer potential for development of a first-ever pharmacological treatment for cocaine addiction. A common beta blocker, propranolol, currently used to treat people with hypertension and anxiety, has shown to be effective in preventing the brain from retrieving memories associated with cocaine use in...

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...
