Aim: To evaluate and document the impacts of re-scheduling codeine to a prescriptiononly medication in Australia in February 2018. Design: Prospective cohort study. Participants completed an on-line survey with a range of outcome measures at four time-points, once before codeine was re-scheduled (November 2017) and three times after the event: 1 month after (February 2018), 4 months after (June 2018) and 12 months after (February 2019). Setting: Australia. Participants: Participants were 260 Australians aged 18 years and above who reported regular over-the-counter (OTC) codeine use and, at the time of the study, were not engaged in treatment for codeine dependence. Measurements: Survey measures included estimates of daily average codeine use (mg) and overall daily average opioid use [calculated using an oral morphine equivalent daily dose (OMEDD, mg)], opioid use disorder with regard to codeine use (using a modified Alcohol Use Disorder and Associated Disabilities Interview Schedule-IV), pain and pain self-efficacy, anxiety and depression and health service use. Findings: A reduction in total daily codeine use (mg) from 64.3 mg [95% confidence interval (CI) = 46.7-81.9] in November 2017 (baseline) to 27.6 mg (95% CI = 19.2-36.0) in February 2019 (final time-point) was observed. A decline in the proportion of participants who met criteria for an opioid use disorder was also evident, with 51.2% (n = 133) at baseline relative to 33.3% (n = 58) at the 12-month follow-up. This study had an overall participant retention rate of 67% at the final time-point. Conclusion: Re-scheduling codeine in Australia has been accompanied by significant reductions in codeine use and prevalence rates of opioid use disorder in a cohort of individuals who regularly use the medication, without apparent adverse impacts on pain or measures of anxiety and depression.

Background and aims: Over‐the‐counter codeine products were up‐scheduled to prescription only in Australia from February 2018. This trend study aimed to identify changes in codeine supply before and after the February 2018 implementation. Design, setting and cases: Time–series regression analysis of monthly medicine supplies in Australia from 2014 to 2018. The February 2018 up‐scheduling was pre‐specified as the intervention; outlier analysis was used to detect automatically sudden unexpected changes before February 2018. Measurements Per‐capita supplies based on national data for pharmaceutical wholesales and population exposure. Weight of supplies in milligrams for low‐dose codeine (≤ 15 mg per tablet or ≤ 1.92 mg per ml, originally sold over the counter but up‐scheduled after February 2018), high‐dose combination codeine (30 mg per tablet, prescription only throughout the study period) and all codeine. Findings Several level shifts in supply occurred during the 5 years, led by one of −4.4% [95% confidence interval (CI) = −6.6 to −2.1%] in high‐dose codeine in 2015, followed by shifts in low‐dose codeine of −40.0% (CI = −46.9 to −32.3%) and −82.2% (CI = −84.3 to −79.9%), respectively, before and after February 2018. High‐dose codeine supply increased by 4.4% (CI = 1.8–7.1%) immediately after up‐scheduling. Also detected were transient increases and decreases in 2016 and 2017. Compared with pre‐2015 levels, the February 2018 up‐scheduling was associated with reductions of 45.7% (CI = 43.2–48.0%) and 89.3% (CI = 87.9–90.6%), respectively, in all and low‐dose codeine supply but no change in high‐dose codeine supply. The level shifts and transient changes were located around various regulatory activities, including public announcements and expert advisory meetings on up‐scheduling. Conclusion: Up‐scheduling of over‐the‐counter codeine products in Australia in 2018 appears to have been associated with a near halving of Australia's national codeine supply. The transition occurred in multiple forms and phases. [ABSTRACT FROM AUTHOR]

Harmonizing global data collection on cannabis use is vital, as laws and policies are rapidly evolving. A similar need exists for measurement of medical cannabis use which, at least in the United States, occurs outside medical systems and medical record-keeping -- ultimately putting patients at risk [ABSTRACT FROM AUTHOR]
