Note. Since multi-drug use was common (mean number of drugs used among rave attendees = 2.6, SD = 2.7, range = 0–18), significance was determined utilizing a Bonferroni correction (p = .05/18 = .003). All comparisons were p < .0001 except for frequent bath salt use, which was p = .0005.

The cell for frequent heroin use among non-attendees contained fewer than five subjects. Bath salt use was only assessed in years 2012–2013. We present raw proportions instead of odds ratios because prevalence of some drugs was too high or too rare, and thus prevented accurate estimations computed using the full value.
