Ecstasy may cause memory problems

Club drug's effects documented in new users

Light use of the club drug Ecstasy may cause subtle memory deficits. People who popped just three Ecstasy tablets a month over the course of a year saw their memory slip on a laboratory test, scientists report online July 25 in Addiction.

The new results offer some of the best evidence yet that the drug can change the brain, says psychiatric neuroscientist Ronald Cowan of Vanderbilt University Medical Center in Nashville.
