That would be extascy. It can have MDMA, coke, heroine and sometimes traces of acid that causes the person to "roll". The side effects you may see are extreme happiness, need for chewing on things (cause your teeth grind), drinking lots of fluids (if she drinks too much it could cause brain hemoraging leading to death), looking away from the person they are talking to (eyes may be dialated), the sex drive heightens, and more. You should get her some help (whatever that may be).
