This study explores PWUD perceptions on recognizing xylazine exposure including its physical effects and clinical harms and how these factors shape their drug use practices.\nMethods: In August 2023, we surveyed adult PWUD clients reporting at least one past-year drug use-related wound across three Massachusetts syringe service programs with high xylazine prevalence. We compared demographics, drug use factors, physical effects, and clinical symptoms between those with and without self-reported past-90-day xylazine exposure and conducted content analysis of open-ended responses.\nResults: Of the 171 respondents, 80% (n=136) reported past-90-day xylazine exposure. The majority of respondents were male, white, non-Hispanic, and aged 36-45 years, with no significant differences by xylazine exposure. Xylazine-exposed participants commonly reported sedation (77%), loss of consciousness (52%), and wounds (91%). Most participants were afraid and frustrated, seeing xylazine as an unwanted contaminant but were often unable to avoid it due to financial constraints, withdrawal symptoms, and limited alternative options.\nConclusion: Syringe service program clients in Massachusetts commonly reported xylazine-adulterated fentanyl exposure, recognized through heavy sedation and skin wounds. Their experiences highlight the urgent need for real-time xylazine detection, safer supply, overdose and sedation risk mitigation, and improved wound prevention and care.<\/p>","DOI":"10.21203\/rs.3.rs-7199750\/v1","type":"posted-content","created":{"date-parts":[[2026,1,13]],"date-time":"2026-01-13T17:29:29Z","timestamp":1768325369000},"source":"Crossref","is-referenced-by-count":0,"title":["Navigating an Unpredictable Supply: Lived Experiences of Xylazine Exposure Among People Who Use Drugs"],"prefix":"10.21203","author":[{"given":"Raagini","family":"Jawa","sequence":"first","affiliation":[{"name":"University of Pittsburgh School of Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Margaret","family":"Shang","sequence":"additional","affiliation":[{"name":"University of Pittsburgh School of Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Samia","family":"Ismail","sequence":"additional","affiliation":[{"name":"Harvard Medical School"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen","family":"Murray","sequence":"additional","affiliation":[{"name":"Boston University Chobanian & Avedisian School of Medicine and Boston Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cristina","family":"Murray-Krezan","sequence":"additional","affiliation":[{"name":"University of Pittsburgh School of Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yihao","family":"Zheng","sequence":"additional","affiliation":[{"name":"University of Pittsburgh School of Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah","family":"Mackin","sequence":"additional","affiliation":[{"name":"AHOPE, Boston Public Health Commission"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenny","family":"Washington","sequence":"additional","affiliation":[{"name":"AHOPE, Boston Public Health Commission"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pedro","family":"Alvarez","sequence":"additional","affiliation":[{"name":"Tapestry Health"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jaime","family":"Dillon","sequence":"additional","affiliation":[{"name":"Life Connection Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gary McMurtrie","family":"BA","sequence":"additional","affiliation":[{"name":"Geisinger Commonwealth School of Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexander Y.","family":"Walley","sequence":"additional","affiliation":[{"name":"Boston University Chobanian & Avedisian School of Medicine and Boston Medical Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jane M.","family":"Liebschutz","sequence":"additional","affiliation":[{"name":"University of Pittsburgh School of Medicine"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","container-title":[],"original-title":[],"link":[{"URL":"https:\/\/www.researchsquare.com\/article\/rs-7199750\/v1","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.researchsquare.com\/article\/rs-7199750\/v1.html","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,6,22]],"date-time":"2026-06-22T16:13:07Z","timestamp":1782144787000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.researchsquare.com\/article\/rs-7199750\/v1"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,1,13]]},"references-count":0,"URL":"https:\/\/doi.org\/10.21203\/rs.3.rs-7199750\/v1","relation":{"is-preprint-of":[{"id-type":"doi","id":"10.1186\/s12954-026-01486-y","asserted-by":"subject"}]},"subject":[],"published":{"date-parts":[[2026,1,13]]},"subtype":"preprint"}}
