Despite recommendation for its use, youths encounter barriers to accessing OAT, including stigma, burden of witnessed dosing, and lack of availability of youth-oriented services and prescribers comfortable treating this population.<\/jats:p><\/jats:sec><jats:sec id=\"ab-zoi230649-5\"><jats:title>Objective<\/jats:title><jats:p>To compare rates of opioid agonist treatment (OAT) and opioid-related mortality between youths aged 15 to 24 years and adults aged 25 to 44 years in Ontario, Canada, over time.<\/jats:p><\/jats:sec><jats:sec id=\"ab-zoi230649-6\"><jats:title>Design, Setting, and Participants<\/jats:title><jats:p>This cross-sectional analysis of rates of OAT and opioid-related deaths between 2013 and 2021 used data obtained from the Ontario Drug Policy Research Network, Public Health Ontario, and Statistics Canada.

In the final year of the study period, 225 youths (146 male [64.9%]) died from opioid toxicity, and 2717 (1494 male [55.0%]) were dispensed OAT. Over the study period, the rate of opioid-related deaths among youths in Ontario increased 369.2% from 2.6 to 12.2 per 100\u202f000 population (48 to 225 total deaths) and the rate of OAT use decreased 55.9% from 3.4 to 1.5 per 1000 (6236 to 2717 individuals). For adults aged 25 to 44 years, the rate of opioid-related deaths increased 371.8% from 7.8 to 36.8 per 100\u202f000 (283 to 1502 deaths), and the rate of OAT increased 27.8% from 7.9 to 10.1 per 1000 population (28\u202f667 to 41\u202f200 individuals). Trends for youths and adults persisted across both sexes.<\/jats:p><\/jats:sec><jats:sec id=\"ab-zoi230649-10\"><jats:title>Conclusions and Relevance<\/jats:title><jats:p>The findings of this study suggest that opioid-related deaths are increasing among youths while OAT use is paradoxically declining. The reasons for these observed trends require further investigation, including a consideration of changing trends in opioid use and opioid use disorder among youths, barriers to OAT, and opportunities to optimize care and reduce harms for youths who use substances.<\/jats:p><\/jats:sec>","DOI":"10.1001\/jamanetworkopen.2023.21947","type":"journal-article","created":{"date-parts":[[2023,7,6]],"date-time":"2023-07-06T15:32:22Z","timestamp":1688657542000},"page":"e2321947","source":"Crossref","is-referenced-by-count":12,"title":["Trends
