Few consumers understand THC levels in cannabis edibles

(University of Waterloo) Few cannabis consumers understand what the THC numbers on packages of cannabis edibles really mean, according to a new University of Waterloo study. The study, which surveyed nearly 1,000 Canadians aged 16 to 30, found that most consumers could not identify whether a cannabis edible contained 'low' or 'high' levels of THC based on the label.
