“…The finding that self-treatment or coping motives are the most common reasons for benzodiazepine misuse has been replicated across heterogenous samples (see Supplementary Materials). However, benzodiazepines are also misused out of curiosity (Chen et al, 2011;Kapil et al, 2014;Kokkevi et al, 2008;Liebrenz et al, 2015) and for recreational motives, such as to get high (Boyd et al, 2006;Brandt et al, 2014b;Calhoun et al, 1996;Johnston and O'Malley, 1986;Kecojevic et al, 2015a;Kelly et al, 2015b;McCabe et al, 2009;McLarnon et al, 2014;Nattala et al, 2011;Nattala et al, 2012;Quintero et al, 2006;Rigg and Ibanez, 2010;Silva et al, 2013a;Terry-McElrath et al, 2009) and to modify the effects of other substances (Section 3.4.5.). Notably, those who report recreational motives also display more problematic use, such as combining benzodiazepines with other substances, reporting greater substance use severity, taking higher doses, taking benzodiazepines by nonoral routes of administration, and illicitly purchasing benzodiazepines (Fatseas et al, 2009;McCabe et al, 2009;McCabe and Cranford, 2012;McLarnon et al, 2014;Stein et al, 2016).…”
