with drugs you can never be sure of the type of memories or flash backs that you're get later down the road. (your professor is as ass because he is only judging this on fictional facts, being that he's probably never tried drugs, he only read about them in the magazines). however, i had both good and bad memories with this drug... most of them good though.
one try of ecstasy will not f*ck you up. a good majority of the people that i know took E and many of them if not all have decent or good paying jobs and have settled down in life. it was just a stage just like how drinking is to many of today's teens.
