You can never be sure unless you buy a drug testing kit. Composition of ecstasy pills change depending on where you live and what year they were made in. There are a lot of different illegal labs, and each lab has it's own composition for ecstasy pills.
For more information, check out http://www.dancesafe.org and http://www.ecstasydata.org/
added info, do not think that ecstasy is not addictive. while the chemical compound for E is not, in itself addicting, most pills that have come out in the last several years are cut with half heroin or cocaine, which may cause the experimenter to crash and crave when coming down.
