很少有研究比较了不同司法管辖区对大麻特定健康风险的了解。本研究旨在研究加拿大和美国各州对大麻健康风险的看法，有和没有法律的非医用大麻。横截面数据来自2018年和2019年国际大麻政策研究在线调查。年龄在16-65岁（n = 72 459）的受访者是从尼尔森小组使用非概率方法招募的。受访者完成了关于大麻对健康的九种影响的问题（包括两个“错误”的控制项目）。收集了社会人口学数据。回归模型测试了不同司法管辖区和大麻使用频率之间的结果差异，并对社会人口因素进行了调整。在各司法管辖区，大麻健康风险声明的同意率最高的是使用大麻后驾驶（66-80%），怀孕/哺乳期间使用（61-71%）和成瘾（51-62%），精神病和精神分裂症风险最低（23-37%）。此外，12-18%和6-7%的受访者分别同意大麻可以治愈/预防癌症和导致糖尿病的“错误”断言。健康知识在加拿大受访者中最高，其次是非医用大麻合法化的美国州，最低的是非医用大麻合法化的州（P < 0.001）。总体而言，调查结果表明，人们对大麻的健康风险认识严重不足，特别是在经常消费者中。
Few studies have compared knowledge of the specific health risks of cannabis across jurisdictions. This study aimed to examine perceptions of the health risks of cannabis in Canada and US states with and without legal non-medical cannabis. Cross-sectional data were collected from the 2018 and 2019 International Cannabis Policy Study online surveys. Respondents aged 16-65 (n = 72 459) were recruited from Nielsen panels using non-probability methods. Respondents completed questions on nine health effects of cannabis (including two 'false' control items). Socio-demographic data were collected. Regression models tested differences in outcomes between jurisdictions and by frequency of cannabis use, adjusting for socio-demographic factors. Across jurisdictions, agreement with statements on the health risks of cannabis was highest for questions on driving after cannabis use (66-80%), use during pregnancy/breastfeeding (61-71%) and addiction (51-62%) and lowest for risk of psychosis and schizophrenia (23-37%). Additionally, 12-18% and 6-7% of respondents agreed with the 'false' assertions that cannabis could cure/prevent cancer and cause diabetes, respectively. Health knowledge was highest among Canadian respondents, followed by US states that had legalized non-medical cannabis and lowest in states that had not legalized non-medical cannabis (P < 0.001). Overall, the findings demonstrate a substantial deficit in knowledge of the health risks of cannabis, particularly among frequent consumers.
