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.

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.
