To assess the prevalence of nonmedical prescription opioid use (NMPOU) in the Canadian general adult population in the context of rising overall prescription opioid (PO) consumption and related problems in North America. ⋯ CADUMS data indicate an extremely low rate of NMPOU, especially given the levels of overall PO use, other PO-use related problems, and NMPOU levels estimated in the general US population where NMPOU has been assessed to be 10 times higher than in Canada. NMPOU survey item construction and response rates appear to strongly influence and potentially compromise NMPOU survey data. Existing NMPOU data and survey methods need to be validated for this important indicator in Canada, where increasing PO use and problem levels have been recognized as a significant and rising public health problem.

Although widely used in the general population, sleeping pills and minor tranquilizers, also known as antianxiety agents, have been associated with undesirable outcomes. Reports about the association of these drugs with an elevated mortality rate are inconsistent and controversial. This study was designed to assess the mortality hazard associated with anxiolytic and hypnotic drug use in the National Population Health Survey in Canada. It was hypothesized that anxiolytic and hypnotic drug use would be associated with an elevated mortality hazard. ⋯ Sedative drug use is associated with a small but significant increase in mortality risk. Further research is required to confirm the mechanisms by which sedative drug use increases mortality risk. Where possible, physicians should systematically consider possibilities for nonpharmacological treatment of sleep disturbances and anxiety.
