“Molly” Sold at Music Festivals Often Contains Other Drugs

People who think they are buying “Molly” at music festivals often end up with pills or powder that contain other drugs, according to a new study.

Researchers studied data collected by the organization DanceSafe, which tested samples of pills or powder sold as Molly at music festivals in the United States between 2010 and 2015, The Washington Post reports.

They found Molly, or MDMA, was present in only 60 percent of the samples collected. The rest contained a mix of ingredients.

While most of the chemicals could not be identified, some samples contained methamphetamine. Several contained a potent form of the amphetamine PMA, which is more likely than many other drugs to be lethal with a single dose.

The findings are published in the Journal of Psychopharmacology.
