The optimal minimum legal age for non-medical cannabis use is 19 years of age, according to a study published in BMC Public Health.
A team of researchers at the Memorial University of Newfoundland, Canada, investigated how Canadians who started using cannabis at several young ages differed across important outcomes (educational attainment, cigarette smoking, self-reported general and mental health) in later-life.
Dr Hai Nguyen, lead author of the study said: “Prior to legalisation, the medical community recommended a minimum legal age of 21 or 25 for non-medical cannabis use in Canada. This recommendation was based on scientific evidence around the potential adverse impacts of cannabis on cognitive development. However, policymakers feared a high minimum legal age may lead to large underground markets, with those under the legal age continuing to use cannabis illegally. Ultimately, a lower legal age of 18 or 19 was decided across provinces, however there remains ongoing debate and calls to raise the legal age to 21.” [Read more…] about Minimum legal age for cannabis use should be nineteen, study suggests
