The motives and methods of methamphetamine and ‘heroin’ co-use in West Virginia

Abstract

Abstract Background Opioid and methamphetamine co-use is increasing across the USA with overdoses involving these drugs also rising. West Virginia (WV) has led the US in opioid overdose death rates since at least 2013 and rising co-use of methamphetamine with opioids has played a greater role in deaths over the last 5 years. Methods This study used rapid ethnography to examine methods and motivations behind opioids and methamphetamine co-use from the viewpoint of their consumers. Participants (n = 30) were people who injected heroin/fentanyl also using methamphetamine who participated in semi-structured interviews. Results We found multiple methods of co-using opioids and methamphetamine, whether alternately or simultaneously and in varying order. Most prioritized opioids, with motives for using methamphetamine forming three thematic categories: ‘intrinsic use’, encompassing both inherent pleasure of combined use greater than using both drugs separately or for self-medication of particular conditions; ‘opioid assisting use’ in which methamphetamine helped people manage their existing heroin/fentanyl use; and ‘reluctant or indifferent use’ for social participation, reflecting methamphetamine’s low cost and easy availability. Conclusions Methamphetamine serves multiple functions among people using opioids in WV. Beliefs persist that methamphetamine can play a role in preventing and reversing opioid overdose, including some arguments for sequential use being protective of overdose. ‘Reluctant’ uptake attests to methamphetamine’s social use and the influence of supply. The impact on overdose risk of the many varied co-use patterns needs further investigation.
