Subject: What is the drug 'extacy'--what are the effects it has on the human body?

Dear Expert,

I've heard of a new illegal drug called "extacy."  People from ages 13 to 
30 are using it.  I would like to know what exactly it is made up of as 
well as what it can do to a person, physically and mentally.  It would be 
of great help if you could respond by Jan. 28.  I would really appreciate 
it.  Any information you have would be helpful as well as related web 
links.  Thank you.
