Knowledge of THC and CBD Levels Among Cannabis Consumers in the United States and Canada

This study focuses on cannabis users, aged 16-65 years, recruited from Canada and the US, from areas that had and had not legalized non-medical cannabis. The findings suggest that labeling practices in the US have a modest, but limited, impact on overall low consumer knowledge of THC and CBD levels.  Additionally, the findings cast doubt on the validity of self-reported cannabinoid levels and suggested that future research should examine labeling practices that may improve consumer knowledge of THC and CBD levels.
