Note. Since multi-drug use was common (mean number of drugs used among infrequent attendees = 2.2, SD = 2.1, range = 0–15; mean number of drugs used among frequent attendees = 3.0, SD = 3.4, range = 0–18), significance was determined utilizing a Bonferroni correction (p = .05/18 = .003). Comparisons were significant at p < .003; however, three comparisons
were not significant before the correction (p > .05) and six
comparisons were no longer significant after the correction (p < .05, but greater than .003).
Cell for frequent LSD use among infrequent 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.
