legalizing and regulating marijuana in canada: review of potential economic, social, and health impacts

notwithstanding a century of prohibition, marijuana is the most widely used illicit substance in canada. due to the growing public acceptance of recreational marijuana use and ineffectiveness of the existing control system in canada, the issue surrounding legalizing this illicit drug has received considerable public and political attentions in recent years. consequently, the newly elected liberal government has formally announced that canada will introduce legislation in the spring of 2017 to start legalizing and regulating marijuana. this editorial aims to provide a brief overview on potential economic, social, and public health impacts of legal marijuana in canada. the legalization could increase tax revenue through the taxation levied on marijuana products and could also allow the government to save citizens’ tax dollars currently being spent on prohibition enforcement. moreover, legalization could also remove the criminal element from marijuana market and reduce the size of canada’s black market and its consequences for the society. nevertheless, it may also lead to some public health problems, including increasing in the uptake of the drug, accidents and injuries. the legalization should be accompanied with comprehensive strategies to keep the drug out of the hands of minors while increasing awareness and knowledge on harmful effects of the drug. in order to get better insights on how to develop an appropriate framework to legalize marijuana, canada should closely watch the development in the neighboring country, the united states, where some of its states viz, colorado, oregon, washington, and alaska have already legalized recreational use of marijuana.
