What's in a Name? Correlates of Ecstasy Users Knowing or Agreeing that Molly is Ecstasy/MDMA

Ecstasy (MDMA) has regained popularity in powder and crystalline form, known as Molly. However, it is unknown whether all Molly users are aware that Molly is ecstasy. A total of 1045 nightclub/festival-attending adults in New York City were surveyed about ecstasy/MDMA/Molly use in 2016. Users were asked if they agreed that Molly is (or is supposed to be) ecstasy/MDMA. Of the 43.5% reporting lifetime use, 84.6% agreed that Molly is ecstasy, 9.5% disagreed, and 5.9% reported not knowing that Molly is ecstasy. Prevalence of use of other drugs (e.g., ketamine, opioids, methamphetamine, NBOMe, 2C series) was lowest among those not knowing that Molly is ecstasy, and highest among those not agreeing that Molly is ecstasy. Those not knowing that Molly is ecstasy were less likely to have used powder or crystal MDMA and less likely to have used in the past 12 months or to report intention to use again. Those disagreeing or not knowing that Molly is ecstasy were at over six times the odds of obtaining ecstasy from an unknown dealer, and those disagreeing were at four times higher odds of having suspected or found out that their ecstasy was adulterated. Results suggest that knowing or agreeing that Molly is ecstasy/MDMA can help indicate ecstasy-related risk.
