The excuse, "I only did it once," no longer stands when it comes to the club drug, Ecstasy.
New research shows brain damage can occur after just one use. That's according to the University of Amsterdam which followed nearly 200 volunteers trying Ecstasy.
They found that even when it was the first time, Ecstasy users showed evidence of some brain damage, including decreased blood flow to certain areas of the brain and changes in brain cell structure.
The study volunteers even had some trouble with certain memory tests. This is a huge concern when you look at statistics from the National Institute on Drug Abuse, which says by the time American students are in the 12th grade, at least five percent have tried Ecstasy.
