The Guardian notes that “anywhere between 30% and 60% of what is being sold as molly or ecstasy in the USA is not in fact MDMA”. Pills in the US are commonly laced with synthetic MDMA replacements such as methylone, butylone and ethylone (nicknamed bath salts). The variety of stimulants that can be included in ecstasy also tamer substances, including caffeine and aspirin. EcstasyData, an independent laboratory pill testing program, found 111 different substances within 528 samples of ecstasy in a 2015 study.
“We don’t really see MDMA any more,” said a Drug Enforcement Agency representative. “You might have a little MDMA in there, but we are seeing a whole slew of other synthetic drugs.”
