“…Qualitative and descriptive results indicate that coingesting benzodiazepines with alcohol increases the intoxicating effects of both substances (Calhoun et al, 1996;Dåderman and Lidberg, 1999;Perera et al, 1987). Mixing benzodiazepines with opioids (Dwyer, 2008;Gelkopf et al, 1999;Hayashi et al, 2013;Lankenau et al, 2012a;Navaratnam and Foong, 1990;Ng et al, 2007;Ross et al, 1996;Ruben and Morrison, 1992;Vogel et al, 2013) and opioid agonist medication (i.e., methadone, buprenorphine) (Gelkopf et al, 1999;Nielsen et al, 2007;Stitzer et al, 1981;Vogel et al, 2013) to enhance the effects of opioids (Dwyer, 2008;Hayashi et al, 2013;Lankenau et al, 2007;Lankenau et al, 2012b;Mateu-Gelabert et al, 2017;Motta-Ochoa et al, 2017;Navaratnam and Foong, 1990;Ng et al, 2007;Ruben and Morrison, 1992) is widespread among those with opioid use and/or injection drug use. Interestingly, one study among individuals in OUD treatment found that nearly 90% of participants who mixed benzodiazepines with other drugs did so to "improve emotional states" (Gelkopf et al, 1999).…”
