Introduction and Aims
Prescription opioid analgesic (POA)-related harms constitute a major public health problem in North America. Ontario features above-average POA use levels in Canada and has seen consistent increases in related mortality and morbidity. Recent studies documented strong correlations between POA dispensing levels and related harm outcomes on population levels. We examined correlations between POA dispensing and key POA-related mortality and morbidity indicators in Ontario, 2005–2011.
