Ontario: Study Shows Vaping Prevalent Among Medical Marijuana Patients
By Derrick Stanley
Vaporization is increasingly becoming the preferred means of patients using medical marijuana, according to a survey with results published in Drug and Alcohol Dependence and in the Harm Reduction Journal.
Investigators from the University of Waterloo, School of Public Health surveyed the consumption habits of 364 patients registered in Canada's medical marijuana program. Authors reported that "the most popular mode of delivery for medical cannabis" among patients was vaporization. Those surveyed in the study said they preferred vaping because it "reduce[d] the negative health consequences associated with smoking."
Another study conducted by researchers at the University of Michigan surveyed 1,485 state-registered medical cannabis patients. Of those surveyed, 39 percent said they have vaporized cannabis during the past month. Most patients acknowledged smoking as the means of drug delivery.
Vaporizer technology heats marijuana to a point where cannabinoid vapors form, but below the point of combustion. Clinical trials evaluating the technology conclude that vaporization is a "safe and effective" cannabinoid delivery mode that "does not result in exposure to combustion gases."
