We analysed interview data from the prospective Ontario HIV Treatment Network Cohort Study from 2008 to 2017. We conducted Latent Class Growth Analyses to describe cannabis use trajectories and chi-square tests to identify trajectory group predictors. Most participants (N = 3,299) were male (81%), gay (57%), current\/former tobacco smokers (58%), and many had significant symptoms of depression (43%). Four cannabis use trajectory groups were identified (Low\/No Use (67%); Increased Use (4%); Decreased use (2%); High Use (26%)). Relative to the Low\/No Use group, membership in the High Use group was associated with several predictors such as being older age, completing university, smoking tobacco, and significant depressive symptoms. Future research should explore the relationship between cannabis use and depressive symptoms, outcomes associated with trajectory groups and changes in use trajectories following recreational legalization. <\/jats:p>","DOI":"10.1521\/aeap.2025.37.2.142","type":"journal-article","created":{"date-parts":[[2025,5,5]],"date-time":"2025-05-05T16:04:52Z","timestamp":1746461092000},"page":"142-159","source":"Crossref","is-referenced-by-count":1,"title":["Cannabis Use Trajectories Among People Living With HIV in the Decade Prior to Recreational Legalization in Ontario, Canada (2008-2017)"],"prefix":"10.1521","volume":"37","author":[{"given":"Tanya","family":"Lazor","sequence":"first","affiliation":[{"name":"Institute for Mental Health Policy Research and Campbell Family Mental Health Research Institute, Centre for Addicton and Mental Health (CAMH), Toronto, Canada, and Canadian Institutes of Mental Health Canadian HIV Trials Network, Vancouver, Canada."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcos","family":"Sanches","sequence":"additional","affiliation":[{"name":"Biostatistics Core, CAMH, Toronto, Canada."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeffrey D.","family":"Wardell","sequence":"additional","affiliation":[{"name":"Institute for Mental Health Policy Research and Campbell Family Mental Health Research Institute, Centre for Addicton and Mental Health (CAMH), Toronto, Canada, and Canadian Institutes of Mental Health Canadian HIV Trials Network, Vancouver, Canada."},{"name":"Department of Psychology, York University, Toronto, Canada, and the Department of Psychiatry, University of Toronto, Canada."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei","family":"Wang","sequence":"additional","affiliation":[{"name":"Biostatistics Core, CAMH, Toronto, Canada."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ann N.","family":"Burchell","sequence":"additional","affiliation":[{"name":"Department of Family and Community Medicine, Temerty Faculty of Medicine, University of Toronto, Toronto, Canada; the Dalla Lana School of Public Health, University of Toronto, Canada; and MAP Centre for Urban Health Solutions, Li Ka Shing Knowledge Institute, St. Michael's Hospital, Unity Health Toronto, Toronto, Canada."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shari","family":"Margolese","sequence":"additional","affiliation":[{"name":"Independent community consultant, Toronto, Canada."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tsegaye","family":"Bekele","sequence":"additional","affiliation":[{"name":"Ontario HIV Treatment Network, Toronto, Canada."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abigail E.","family":"Kroch","sequence":"additional","affiliation":[{"name":"Dalla Lana School of Public Health, University of Toronto, Canada, and the Ontario HIV Treatment Network, Toronto, Canada."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sergio","family":"Rueda","sequence":"additional","affiliation":[{"name":"Institute for Mental Health Policy Research and Campbell Family Mental Health Research Institute, Centre for Addicton and Mental Health (CAMH), Toronto, Canada, and Canadian Institutes of Mental Health Canadian HIV Trials Network, Vancouver, Canada."},{"name":"Department of Psychiatry, University of Toronto, Canada; and the Institute of Medical Science, University of Toronto, Canada."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"OHTN Cohort Study Group","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"377","reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1212\/01.wnl.0000253187.66183.9c"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1080\/13556219971623"},{"key":"ref4","volume-title":"AUDIT: The Alcohol Use Disorders Identification Test: Guidelines for use in primary care","author":"Babor T.
