^aPrEP and MOUD activities are reinforced on independent schedules, such that failure to complete the planned MOUD activity does not impact draws for the PrEP planned activity, and vice versa. The bonus is only earned if the participant provides verified evidence of completing both activities in a given week (i.e., completed both the PrEP activity and the MOUD activity as listed on the contract).

^bPrEP: Pre-exposure Prophylaxis; MOUD: Medications for Opioid Use Disorder; OUD: Opioid Use Disorder; N/A: Not applicable

^cIf a participant reports no progress towards PrEP initiation or has initiated PrEP, but is non-adherent, no draws will be awarded for that session and the number of draws will reset to the initial value of 3 for the next demonstration of verified activity completion.

^dIf a participant reports no progress towards MOUD or other OUD-related care, no draws will be awarded for that session and the number of draws will reset to the initial value of 3 for the next demonstration of verified activity completion.
