The current study examined the self-reported impact of the COVID-19 pandemic on cannabis consumption and behaviors among past 12-month cannabis consumers in Canada and the U.S. across different cannabis laws. Cross-sectional survey data were collected in 2020 from respondents recruited through online commercial panels, aged 16-65, who consumed cannabis in the past 12 months (n = 13,689). Weighted multinomial logistic regression models examined differences between jurisdictions for five outcomes: 1) cannabis consumption; 2) use of product types; 3) use of sources to obtain cannabis; 4) legality of source used; and 5) access to cannabis. Approximately one third of cannabis consumers reported changes to their consumption during the pandemic. Edibles (23% - 31%) and dried flower (21% - 30%) were the two most common products that respondents reported they were "more likely" to use during the pandemic. Most consumers reported "no difference" to changes in sourcing cannabis. Compared to consumers in U.S. recreational states, consumers in U.S. medical (AOR = 1.27, 95% CI: 1.07, 1.50) and illegal states (AOR = 1.22, CI: 1.00,1.48) had higher odds of reporting it was "harder" to access cannabis, and consumers in Canada had lower odds (AOR = 0.73, CI: 0.63,0.84). Future research should examine whether these changes remain after public health restrictions due to the pandemic are removed.
当前的研究调查了新冠疫情对加拿大和美国过去12个月内吸食大麻的人群在不同大麻法律下的大麻消费及行为的自我报告影响。2020年通过在线商业面板招募了年龄在16 - 65岁之间、过去12个月内吸食过大麻的受访者（n = 13689），收集了横断面调查数据。加权多项逻辑回归模型研究了五个结果在不同司法管辖区之间的差异：1）大麻消费；2）产品类型的使用；3）获取大麻的来源使用；4）所使用来源的合法性；5）获取大麻的难易程度。大约三分之一的大麻消费者报告在疫情期间其消费发生了变化。食用大麻制品（23% - 31%）和干花（21% - 30%）是受访者报告在疫情期间“更有可能”使用的两种最常见产品。大多数消费者报告在获取大麻的来源方面“没有变化”。与美国娱乐用大麻合法化州的消费者相比，美国医用大麻合法化州（调整后比值比[AOR] = 1.27，95%置信区间[CI]：1.07，1.50）和非法州（AOR = 1.22，CI：1.00，1.48）的消费者报告获取大麻“更难”的几率更高，而加拿大的消费者几率更低（AOR = 0.73，CI：0.63，0.84）。未来的研究应考察在因疫情实施的公共卫生限制措施解除后，这些变化是否仍然存在。
