^aUse of cannabis-containing products in the past 12 months
^bNo use of cannabis-containing products in the past 12 months
^cCumulative percentage may be greater than 100, as multiple categories may be relevant to each participant
^dUse over the past 3 months
^eCoefficients of variation are within the range of 16.6 to 33.3%. Therefore, it is required to report by the Statistics Canada that estimates are associated with high levels of error (Statistics Canada 2021)
^fCoefficients of variation are greater than 33.3%. Therefore, estimates do not meet Statistics Canada’s quality standards. Conclusions based on this data will be unreliable and most likely invalid (Statistics Canada 2021). All percentages reported are weighted using probability weights from Statistics Canada
