The legality, recreational and medical use of cannabis varies widely by country and region but remains largely prohibited internationally. In October 2018, Canada legalized the recreational use of cannabis-a move many viewed as controversial. Proponents of legalization have emphasized the potential to eradicate the marijuana black market, improve quality and safety control, increase tax revenues, improve the availability of medical cannabis, and lower gang-related drug violence. Conversely, opponents of legalization have stressed concerns about cannabis' addictive potential, second-hand cannabis exposure, potential exacerbation of underlying and established mental illnesses, as well as alterations in perception that affect safety, particularly driving. This systematic review synthesizes recent international literature on the clinical and public health implications of cannabis legalization.
大麻的合法性、娱乐性和医疗用途因国家和地区而异，但在国际上仍基本被禁止。2018 年 10 月，加拿大将大麻的娱乐性使用合法化，此举引发了广泛争议。合法化的支持者强调了消除大麻黑市、提高质量和安全控制、增加税收、增加医用大麻供应以及降低与帮派有关的毒品暴力的潜力。相反，合法化的反对者则强调了对大麻成瘾潜力、二手大麻暴露、潜在加重现有精神疾病、以及影响安全的感知改变的担忧，特别是驾驶安全。本系统评价综合了最近关于大麻合法化对临床和公共卫生影响的国际文献。
