Bath Salts Often Added to “Molly,” Making the Drug More Dangerous
The club drug “Molly” is often laced with other synthetic drugs such as bath salts, making it more dangerous, according to law enforcement officials.
Molly, a club drug blamed for several recent deaths among young people attending music festivals, is sold as a pure form of Ecstasy, or MDMA. Drug dealers are now selling a variety of potentially more dangerous drugs under the name Molly, according to The Wall Street Journal.
