Canada legalized cannabis for adult (recreational) use in 2018, alongside regulations on the sale, use, and possession of cannabis. To date, there is little evidence on consumer perceptions and support of cannabis regulations. This study examined perceptions of nine cannabis regulatory policies, including differences by cannabis consumption and provincial policy. National survey data were analyzed from Wave 5 of the International Cannabis Policy Study conducted online in 2022 with 16,812 Canadians aged 16+ years, 62% of which were assigned female-at-birth. Weighted logistic regression models examined support for nine policy variables. Support among Canadians was greatest for health warnings on cannabis products (62.6%), legalization for adult use (58.5%), and retail store window-coverings (49.2%), followed by a vaping/extract THC limit (40.1%), retail store density (35.5%), government-only store models (34.6%), the THC limit on edibles (32.3%), and advertising restrictions (31.8%). The 30 g purchasing limit had the least consumer support (10.1%). As consumption increased, opposition generally increased, although support remained high among consumers. Compared to non-consumers, daily consumers were more likely to oppose window-coverings (OR = 1.43, CI95 = 1.16-1.75, = .001). Where policies differed provincially, few differences in support were observed. No differences in support for THC limits on vaping/extracts were observed between Newfoundland, Nova Scotia, and Quebec versus the rest of Canada, despite stronger vaping/extract regulations (OR = 1.05, CI95 = 0.87-1.28, = .597). Canadians generally support existing cannabis regulations that were implemented to support public health. The high level of support among consumers suggests that the comprehensive regulations may not undermine transitions to legal retail sources.
2018年，加拿大将成人（娱乐性）使用大麻合法化，并出台了有关大麻销售、使用和持有方面的规定。迄今为止，关于消费者对大麻法规的看法和支持情况的证据很少。本研究考察了对九项大麻监管政策的看法，包括不同大麻消费情况和省级政策之间的差异。分析了2022年在线开展的国际大麻政策研究第5波的全国调查数据，调查对象为16岁及以上的16812名加拿大人，其中62%出生时被认定为女性。采用加权逻辑回归模型考察对九个政策变量的支持情况。加拿大人对大麻产品健康警示的支持率最高（62.6%），对成人使用合法化的支持率为（58.5%），对零售店橱窗遮蔽的支持率为（49.2%），其次是雾化/提取四氢大麻酚（THC）限量（40.1%）、零售店密度（35.5%）、仅政府经营的商店模式（34.6%）、食品中THC限量（32.3%）以及广告限制（31.8%）。30克的购买限量得到的消费者支持最少（10.1%）。随着消费量的增加，反对意见通常也会增加，不过消费者中的支持率仍然很高。与非消费者相比，日常消费者更有可能反对橱窗遮蔽（比值比=1.43，95%置信区间=1.16-1.75，P=0.001）。在省级政策存在差异的地方，支持率几乎没有差异。尽管雾化/提取法规更为严格，但在纽芬兰、新斯科舍和魁北克与加拿大其他地区之间，对雾化/提取物中THC限量的支持率没有差异（比值比=1.05，95%置信区间=0.87-1.28，P=0.597）。加拿大人普遍支持为保障公众健康而实施的现有大麻法规。消费者的高支持率表明，这些全面的法规可能不会阻碍向合法零售渠道的转变。
