Cannabis Projects

The Cannabis Act (Bill C-45) became effective on October 17, 2018 in Canada, which outlines the legal and regulatory framework to control the legal production, distribution, sale and possession of cannabis. The rationale for cannabis legalization includes prevention of youth access and displacement of the illegal cannabis market. The ultimate goal is to facilitate a public health approach to cannabis consumption in Canada. Adults are now allowed to possess up to 30 grams of cannabis, purchase cannabis from authorized retailers and grow up to four cannabis plants per residence for personal consumption. Researchers from OCRINT secured funding from the Canadian Institutes of Health Research (CIHR) and Canadian Centre on Substance Use and Addiction (CCSA) to examine the population-health impacts of cannabis legalization. They are assessing a wide range of outcomes, including patterns of consumption of cannabis, patterns of consumption of other substances, cannabis-related treatment admissions and cannabis-related traffic fatalities. The publications resulting from this research project are listed below:
