: Canada legalized non-medical cannabis in October 2018. Little research has examined the change in perceived access to cannabis after legalization in Canada, including the perceived ease of purchasing cannabis in a legal market.: To: 1) describe changes in perceived ease of access to cannabis before and one year after legalization; 2) examine associations between perceived ease of cannabis access and cannabis use; and 3) examine associations between perceived ease of purchasing from cannabis stores and cannabis use.: Repeat cross-sectional data come from Canadian respondents aged 16-65 (50% male) in August-October 2018 (n = 10,057) and September-October 2019 (n = 15,256). Respondents were recruited through commercial online panels. Multivariable logistic regression models examined correlates of perceived proximity to retail stores, ease of access, and ease of purchasing from retail stores.: Canadians who do not consume cannabis were more likely to report "easy" access to cannabis in 2019 than in 2018 (55% vs. 42%; AOR = 1.80:1.66,1.96). All cannabis consumer groups were more likely to report living 15 minutes or less from a retail store in 2019 than 2018, but the association was strongest among non-consumers in 2019 vs 2018 (AOR = 2.01:183,2.21 vs. AOR = 1.33:1.03,1.73 for daily consumers). Non-daily and daily cannabis consumers were more likely to report it was easy to purchase from an illegal (AOR ranged 1.58-2.22) or legal (AOR ranged 1.31-1.39) store than non-consumers in 2019.: Most cannabis consumers and non-consumers perceived access to cannabis as 'easy' before legalization and the percentage increased one year after legalization.
加拿大于 2018 年 10 月将非医用大麻合法化。很少有研究调查大麻合法化后加拿大对大麻获取便利性的感知变化，包括在合法市场购买大麻的便利性。
1）描述合法化前后大麻获取便利性的变化；2）检查大麻获取便利性与大麻使用之间的关联；3）检查从大麻商店购买大麻的便利性与大麻使用之间的关联。
重复的横截面数据来自 2018 年 8 月至 10 月（n=10057）和 2019 年 9 月至 10 月（n=15256）年龄在 16-65 岁的加拿大受访者（50%为男性）。受访者通过商业在线小组招募。多变量逻辑回归模型检查了接近零售店的感知距离、获取便利性和从零售店购买便利性的相关因素。
在 2019 年，不消费大麻的加拿大人更有可能报告“容易”获取大麻（55%比 42%；AOR=1.80:1.66，1.96）。所有大麻消费群体在 2019 年比 2018 年更有可能报告距离零售店 15 分钟或更短的距离，但在 2019 年，非消费者的关联最强（AOR=2.01:183，2.21 比 AOR=1.33:1.03，1.73 用于每日消费者）。非每日和每日大麻消费者更有可能报告从非法（AOR 范围 1.58-2.22）或合法（AOR 范围 1.31-1.39）商店购买大麻更容易，而非消费者在 2019 年报告更容易。
在合法化之前，大多数大麻消费者和非消费者都认为获取大麻“容易”，并且在合法化一年后，这一比例有所增加。
