Diffusion of Ecstasy in the Electronic Dance Music Scene.

Ecstasy (MDMA, Molly) is among the most prevalent drugs used by people who attend electronic dance music (EDM) events; however, little recent research has examined diffusion of ecstasy in this high-risk population.

Methods: 1,020 EDM event-attending adults (aged 18-40) were surveyed in NYC in 2018 using time-spacing sampling. Participants were asked about past-year ecstasy use, and those reporting use were asked where they initiated use and whether their first use was planned. They were also asked whether they have ever given someone their first dose and whether they were likely to use in the future. Prevalence and correlates of these outcomes were estimated among those reporting past-year use.

Results: An estimated 31.0% of participants used ecstasy in the past year. Of these, 42.9% used ecstasy for the first time in an unplanned manner and initiation most commonly occurred at EDM festivals (33.4%), followed by nightclubs (24.3%). An estimated 39.4% reported having given someone their first dose of ecstasy and 60.2% reported being likely to use again. Hispanic and Asian participants were at higher risk for their first dose being unplanned, and those who used LSD in the past year were at higher risk for giving someone their first dose (aPR = 1.78, 95% CI = 1.20-2.65). Older participants (aPR = 1.03, 95% CI = 1.01-1.06), females (aPR = 1.46, 95% CI = 1.13-1.89), and those who used LSD in the past year (aPR = 1.42, 95% CI = 1.14-1.76) were more likely to report being likely to use again in the future.

Conclusions: Results provide insight regarding diffusion and initiation of ecstasy in the EDM scene. Findings can inform prevention and harm reduction efforts.
