One key to successfully helping people recover from substance abuse is to understand the biological reactions caused by prolong drug or alcohol use. Over time, the brain's chemistry is affected by substance use and no longer functions normally.

"The effect of addictive substances on the brain might chemically impair key survival functions - eating, drinking, even reproduction. Substance abuse also appears to interfere with the chemical wiring that connects emotion to action, which could account for why alcoholics and addicts often seem immobilized and unable to help themselves."

Understanding these types of things helps get rid of the stigma often association with substance abuse and addiction - which is still often viewed simply as a lack of willpower or a kind of "moral failure". In reality, substance abuse is a deeply rooted, physiological issue that takes time and support to overcome.

Researchers at the University of Sydney in Australia found that the chemical in marijuana affects adult and adolescent rats differently. In particular, adolescent rats lost more long and short-term memory.

Dr. Ian McGregor and his colleagues tested the rats' memories right after they ingested the drug, and again after all traces of it had left their bodies. The adolescent rats had deeper memory impairment. In addition, the adult rats avoided the "room" where the marijuana had been "served," but the teen rats did not.

"Cannabis produces much greater long-term changes in adolescent than adult rat brains," Dr. McGregor said.

The number of patients between the ages of 16 and 25 being treated in Victoria for alcohol-related brain injuries rose 16 percent in the last ten years. Many attribute this rise to the high concentration of bars and clubs in the city center.

"Staff at Arbias, which provides support to people with alcohol or substance-related brain damage, are treating about 600 young people annually in Melbourne, up from about 120 a decade ago."

There are currently more than 1,000 establishments in Melbourne's city center that are licensed to serve alcohol. Many of them are open well past 1am. These and other statistics are causing many in Australia to call for the legal drinking age to be raised to twenty-one. Read more at TheAge.com.au.

A small study indicates that alcohol may damage the brains of women more extensively than male brains.

Researchers tested 24 female alcoholics, 78 male alcoholics and 68 non-users of both sexes. The non-alcoholics scored the best on tests of working memory, visuospatial skills, and psychomotor speed. However, female alcoholics performed significantly worse than the males, even in instances when they had consumed less alcohol over shorter lengths of time.

Barbara Flannery, a senior scientist at the RTI International research institute in Baltimore, said she believes that there should be "gender-sensitive public awareness programs" about alcoholism.

Other studies have proven that the higher percentage of body fat in females makes alcohol more toxic for them. There is also evidence that adolescent girls who drink incur damage not only to their developing brains but also to their reproductive systems.

This study appears in the May issue of Alcoholism: Clinical and Experimental Research.
