On Oct. 17, 2018, Canada legalized recreational cannabis with the dual goals of reducing youth use and eliminating the illicit cannabis market. We examined factors associated with access to physical cannabis stores across Canada 6 months following legalization.
We extracted the address and operating hours of all legal cannabis stores in Canada from online government and private listings. We conducted a descriptive study examining the association between private/hybrid (mixture of government and private stores) and government-only retail models with 4 measures of physical access to cannabis: store density, weekly hours of operation, median distance to the nearest school and relative availability of cannabis stores between low- and high-income neighbourhoods.
Six months after legalization, there were 260 cannabis retail stores across Canada: 181 privately run stores, 55 government-run stores and 24 stores in the hybrid retail system. Compared to jurisdictions with a government-run model, jurisdictions with a private/hybrid retail model had 49% (95% confidence interval 10%-200%) more stores per capita, retailers were open on average 9.2 more hours per week, and stores were located closer to schools (median 166.7 m). In both retail models, there was over twice the concentration of cannabis stores in neighbourhoods in the lowest income quintile compared to the highest income quintile.
Marked differences in physical access to cannabis retail are emerging between jurisdictions with private/hybrid retail models and those with government-only retail models. Ongoing surveillance including monitoring differences in cannabis use and harms across jurisdictions is needed.
2018年10月17日,加拿大将休闲用大麻合法化,目标是减少青少年使用并消除非法大麻市场。我们研究了大麻合法化6个月后加拿大各地实体大麻商店的可及性相关因素。
我们从政府在线列表和私人列表中提取了加拿大所有合法大麻商店的地址和营业时间。我们进行了一项描述性研究,考察了私人/混合(政府商店和私人商店混合)和仅政府经营的零售模式与大麻实体可及性的4项指标之间的关联:商店密度、每周营业时间、到最近学校的中位距离以及低收入和高收入社区之间大麻商店的相对可及性。
合法化6个月后,加拿大共有260家大麻零售店:181家私人经营商店、55家政府经营商店和24家混合零售系统商店。与采用政府经营模式的司法管辖区相比,采用私人/混合零售模式的司法管辖区人均商店数量多49%(95%置信区间10%-200%),零售商平均每周多营业9.2小时,商店距离学校更近(中位距离166.7米)。在两种零售模式中,收入最低五分位数社区的大麻商店集中度是收入最高五分位数社区的两倍多。
采用私人/混合零售模式的司法管辖区与仅采用政府零售模式的司法管辖区在大麻零售的实体可及性方面正出现显著差异。需要进行持续监测,包括监测不同司法管辖区在大麻使用和危害方面的差异。
