BackgroundIn Canada, harm from nonmedical prescription opioid analgesic (POA) use (NMPOU) has increased in recent years; however, there are limitations to the current estimates of NMPOU. The 2009 Canadian Alcohol and Drug Use Monitoring Survey presents an opportunity to produce more accurate estimates of NMPOU.ObjectivesTo determine the prevalence of POA use, NMPOU and use of pain relievers to 'get high', and to assess correlations of these indicators with age, sex and provincial levels of dispensed POAs in Canada in 2009.MethodsData regarding POA use were obtained from the 2009 Canadian Alcohol and Drug Use Monitoring Survey (n=13,032). The amount of POAs dispensed in standardized daily doses was obtained from a representative sample of 2700 retail pharmacies across Canada. Associations among POA use, age, sex and the amount of POAs dispensed were evaluated using regression models. Differences in POA use across provinces were assessed using the Wald test.ResultsIn Canada in 2009, the prevalence of POA use was 19.2% (95% CI 18.0% to 20.5%), NMPOU was 4.8% (95% CI 4.1% to 5.5%) and the use of pain relievers to get high was 0.4% (95% CI 0.1% to 0.8%). NMPOU was significantly associated with age. The use of pain relievers to get high varied significantly across provinces, while POA use and NMPOU did not show significant variations. The amount of POAs dispensed per province was not significantly correlated with any type of POA use.ConclusionsThese findings confirm high POA use and NMPOU across Canada. Research is required to identify determinants of NMPOU.
