Eligibility Criteria for PWUD Intervention Participants (i.e., intervention participants who use drugs). 1) People who use drugs (PWUD) recruited directly to the intervention arm of the study (i.e., not by a non-PWUD peer partner) by West Side Heroin and Opioid Task Force or snowball sampling will be eligible to participate in the intervention if they live on the West side of Chicago, report that they currently use opioids (i.e., in the last week), know at least one person living in Chicago who has not used opioids in the last year and who they are willing to try to recruit to the study as someone who might be willing to offer them harm reduction support, are at least 18 years old, and are able to be interviewed in English and/or Spanish. 2) PWUD recruited to the intervention arm of the study by their non-PWUD peers who are enrolled in the study will be eligible to participate in the intervention group if they live in Chicago, have a study recruitment coupon from a non-PWUD participant, report that they currently use opioids (i.e., in the last week), state that they are willing to learn how their peer might be able to support them, are at least 18 years of age, and are able to be interviewed in English and/or Spanish. Eligibility Criteria for Non-equivalent Comparison Group Participants. Comparison group participants will be eligible to participate in the comparison arm of the study if they report currently using opioids (i.e., in the last week), have accessed harm reduction services from one of the study's community partners (Community Outreach Intervention Projects; or West Side Heroin and Opioid Task Force) in the last six months, are at least 18 years old, and are able to speak English and/or Spanish. These individuals who are recruited to the comparison group will not be eligible to participate in the intervention unless they are given a recruitment coupon by a non-PWUD peer.
