Cannabis use appears to be more common among emerging adults (EA) compared to other age groups in Canada. Substance use or misuse peaks during emerging adulthood and may be influenced by political and public health deviations. This study aimed to (1) examine trends in frequency and quantity of cannabis consumption among EA before and after: legalization of cannabis in Canada, the “e-cigarette or vaping product use associated lung injury” (EVALI) outbreak, and COVID-19; and (2) to examine sex-specific differences in cannabis use and associations with respiratory symptoms. There was a continuous and gradual increasing trend in quantity and frequency of smoking and vaping cannabis over time. Quantity and frequency of consumption was higher among males than females. Frequency of vaping only/dual consumption may be protective of respiratory symptoms among females. Increased consumption demonstrates a need for policy measures to address excessive use following political changes and during public health events.
