Data collected include use of psychoactive prescription drugs in the past week. In this cross\u2010sectional study, we included patients aged at least 18\u2009years, on opioid agonist treatment and reporting psychoactive prescription drug use in the past week from 2014 to 2023. The outcome was psychoactive prescription drug misuse (i.e., abuse and\/or dependence, illegal acquisition and diverted route of administration) in the past week. We conducted disproportionality analyses to identify prescription drugs associated with misuse. We calculated the prevalence of use and misuse for each prescription drug to estimate trends.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      We included 9631 patients.

Trends in misuse paralleled trends in use for most prescription drugs. The sharpest increase in misuse included abuse and\/or dependence (+2366%, from 0.9 per 1000 patients in 2014 to 23.0 per 1000 patients in 2023) for pregabalin. Conversely, the sharpest decrease in misuse included illegal acquisition (\u221259%, from 82.1 per 1000 patients in 2014 to 33.9 per 1000 patients in 2023) for morphine.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>In this population, prescription drug misuse primarily included opioid analgesics and increasingly pregabalin.
