Parents, beware: ‘Molly’ is not your child’s new best friend. While the drug has a pretty-sounding name, the effects can be deadly, according to the Orlando Sentinel. Known also as MDMA or Ecstasy, Molly was responsible for the death of a New Hampshire college student over Labor Day weekend, as well as several other recent deaths. Molly tends to be a more potent and purer form of Ecstasy than was found at raves during the past two decades, making it even more dangerous than the drug that Gen X-ers remember.
