Splitting and sharing inside an OPS/SCS prevents harms related to splitting and sharing outside of an OPS/SCS. Failure to allow splitting and sharing within exempted services increases risk for PWUD. Services that prohibit splitting and sharing experience scope creep when they have to police their own clients/participants. The results? PWUD are forced to split and share their drugs outside of the site, increasing the risk of experiencing discrimination, and criminalization. When arbitrary rules hinder accessibility to life saving services, the outcomes are fatal. This sample protocol has been produced to guide OPS/SCS operators in navigating this emerging practice, and aims to strengthen accessibility to the legal consumption context offered by OPS/SCS and to reduce the risks related to consumption of drugs.
