The Canadian Centre on Substance Abuse has called for THC limits for edible cannabis products to be set at a maximum of 5 milligrams per package. The recommendation is part of a brief submitted to Health Canada as the federal health agency develops regulations for marijuana edibles and extracts, which are scheduled to be legalized in Canada later this year. The country legalized cannabis flower and oils for recreational use and sale in October of last year.
Under current regulations for medical marijuana products, cannabis edibles are capped at 10 milligrams of THC per package. But the CCSA, an agency that was created by Parliament to provide national leadership to address substance use, believes that the maximum allowed should be lowered for several reasons. The CCSA brief notes that edible products can be unwittingly ingested by children or adults who are not aware they contain THC, that edibles carry a risk of over-consumption because of the increased time for ingested THC to take effect, and “the duration of impairment associated with the increased duration of effect when THC is ingested rather than smoked.” A smaller unit size would also allow for more selective and accurate dosing, according to the brief.
