“…Specifically, among high school seniors in the MTF study, any attendance was related to increased risk of using 18 different drugs, and more frequent attendance was associated with even higher prevalence of use of each drug (Palamar, Griffin-Tomas, et al, 2015). Other studies have found an association between higher frequency of EDM event attendance and ecstasy use (Abrahamsson & Hakansson, 2013), and a recent study found that regular EDM attendance was associated with three times the odds for high levels of use, and that knowing more than ten ecstasy users was associated with more than double the odds for high levels of use (Smirnov, Najman, Hayatbakhsh, Plotnikova, et al, 2013). Increased risk may be due, in part, to stronger affiliation with drug scenes as previous research has found that ecstasy use is associated with peers and close friends who also use, and offers to try the drug (Ter Bogt & Engels, 2005; Martins, Storr, Alexandre, & Chilcoat, 2008a, 2008b; Smirnov, Najman, Legosz, Wells, & Kemp, 2013; Smirnov, Najman, Hayatbakhsh, Wells, et al, 2013; Vervaeke, Benschop, van den Brink, & Korf, 2008; Vervaeke, van Deursen, & Korf, 2008).…”
