Correction: Opioid losses in terms of dosage and value, January 2012 to September 2017: a retrospective analysis of Health Canada data

An error occurred in an article published Feb. 24, 2020.1

The first paragraph of the article included the sentence “Since 2006, any individuals or organizations in Canada licensed to produce, package, assemble, sell or transport opioids are mandated to report losses to Health Canada by fax or email within 10 days (see reporting form in Appendix 1, section 9, available at www.cmajopen.ca/content/8/1/E113/suppl/DC1).” The authors have been alerted that this requirement was present before the Controlled Drugs and Substances Act and have verified that it is present in the 1961 Narcotic Control Act. The sentence has been revised to “Dating back to at least 1961, any individuals or organizations in Canada licensed to produce, package, assemble, sell or transport opioids are mandated to report losses to Health Canada by fax or email within 10 days (see reporting form in Appendix 1, section 9, available at www.cmajopen.ca/content/8/1/E113/suppl/DC1).” The original reference 12 (to the Narcotic Control Regulations)2 has been replaced with a reference to the Narcotic Control Act.3

The article has been corrected at cmajopen.ca.
