Access and barriers to safer supply prescribing during a toxic drug emergency: A mixed methods study of implementation in British Columbia, Canada. Substance Abuse Treatment Prevention and Policy, 19(1). https://doi.org/10.1186/s13011-024-00625-7https://doi.org/10.1186/s13011-024-00625-7https://hdl.handle.net/1828/21661In March 2020, British Columbia, Canada, introduced prescribed safer supply involving the distribution of pharmaceutical grade alternatives to the unregulated toxic drug supply. Prior research has demonstrated positive impacts on overdose mortality, but with limited reach to people who use substances. Objectives of this study were to (1) identify barriers to accessing safer supply prescribing among people who use substances; and (2) determine whether and how barriers differed between people with and without prescriptions, and between urban and rural settings.enCC BY-NC-ND 4.0harm reductionimplementation scienceoverdosepublic healthsafer supplysubstance useArticle
