Brief Summary
The purpose of this study is to assess the feasibility and acceptability of providing oral pre-exposure prophylaxis (PrEP) and opioid agonist therapy (OAT) simultaneously in existing pharmacy-based programs operating in Alberta and Saskatchewan, to collect preference, adherence, and persistence data on oral PrEP, and to assess interest / acceptability of long-lasting injectable options for human immunodeficiency virus (HIV) prevention.

Outcome Measures
Primary Outcomes (2)
Oral PrEP use in an OAT setting at 6 months follow-up: Review data from participant screening and clinical follow-up, and compare it to baseline PrEP use to assess uptake
The proportion of participants: * Using PrEP within the clinical programs at baseline * Who initiate PrEP (take one dose) when approached for study enrollment and 1, 3, and 6 months from study initiation * Maintained on PrEP at 6 months (have taken PrEP at least once a week)
Start of 6-month recruitment period to 6 months following the end of the recruitment period
Oral PrEP use in an OAT setting at 6 months follow-up: Record the time from offer to acceptance of PrEP
From the time that PrEP was offered to the acceptance of PrEP or the end of the 6-month recruitment period
Secondary Outcomes (12)
Compare usage and clinical outcomes between individuals who initiate PrEP and those who do not at 1, 3, 6, 9, and 12 months
