Learning how Cocaine Addiction Works

Thursday, October 28th, 2010

Researchers have learned how cocaine becomes addictive and changes the brain. The results of the study may help develop new ways of treating cocaine addiction.

The researchers at Mount Sinai School of Medicine learned that the two main neurons (D1 and D2) in the nucleus accumbens region of the brain exert opposite effects on cocaine reward.

 

 

 

 

 

“The data suggest a model whereby chronic exposure to cocaine results in an inbalance in activity in the two nucleus accumbens neurons: increased activity in D1 neurons combined with decreased activity in D2 neurons,” said Mary Kay Lobo, PhD, lead study researcher.

The study was done using optogenetics, which controls neuronal activity in rodents.

Sharpe Drop for Cocaine and Crack Addicts in Treatment

Monday, October 18th, 2010

For the first time, the National Treatment Agency for Substance Misuse (NTA) in Britain indicates a sharp drop in the numbers of drug abusers getting treatment for cocaine and crack addiction. The drop is especially noticeable among young adults between the ages of 18 and 24. The drop reflects recent evidence of a decline in the popularity of cocaine.

The NTA report is published as other research estimates that the number of heroin addicts in Britain has dropped by almost 11,000 people in the past few years. The amount of heroin and crack addicts is also falling among young adults.

“Our priority now is to refocus the drug treatment system in England to deliver sustained recovery from addiction so that users can get off drugs altogether, start reliving their lives and contribute to their families, communities and society,” said Paul Hayes, NTA’s Chief Executive.

Illegal Drug Use Climbed to 10 Year High in 2009

Monday, September 27th, 2010

The annual report from the Substance Abuse and Mental Health Services Administration found that the rate of illegal drug use climbed in 2009 to the highest level in almost ten years. The increase was profound in marijuana, ecstasy and methamphetamine abuse.

The director of the Office of National Drug Control Policy, Gil Kerlikowske, was not surprised by the 9 percent increase in drug use. This is in part due to “eroding attitudes” about the perception of harm from illegal drugs and more states allowing the use of marijuana for medical reasons.

According to the report, marijuana use rose by 8 percent and kept its status as the most often used drug. Cocaine abuse continues to drop from its peak in 2006. About 21.8 million Americans reported using illegal drugs in 2009, which is the highest number since the survey began in 2002.

Paris Hilton Arrested for Felony Cocaine Possession

Thursday, September 2nd, 2010

Another celebrity is in trouble with the law. Paris Hilton was arrested last Friday in Las Vegas after a police officer smelled marijuana smoke from the SUV driven by her boyfriend. When the officer stopped Hilton and Cy Waits, he found cocaine in Hilton’s purse. 

Hilton, 29, was arrested on suspicion of felony cocaine possession. Waits was arrested on misdemeanor suspicion of driving under the influence of alcohol and drugs.

Hilton was released on bail a few hours later. If convicted, Hilton would receive probation. Any violation of that probation would result in Hilton serving anywhere from one to four years in Nevada state prison.
