大麻警告标签可以传达风险,但对不同产品类型的警告认知和差异的研究很少。在2019年的一项在线调查中,1000名美国成年人(500名大麻使用者和500名使用烟草的大麻非使用者)被随机分配观看干花或可食用大麻包装图像上显示的无警告或美国或加拿大四种警告之一。这些警告描述了大麻与精神病、成瘾、缺乏FDA监管和驾驶障碍有关的风险。我们使用线性回归来检验警告和产品危害的感知,作为产品类型(干燥或可食用)和警告的函数。我们检查了哪些警告参与者选择为最有效的阻止青少年使用和驾驶障碍。参与者发现成瘾警告(大麻使用者:B= - 1.04, p<0.001;大麻非使用者:B= 1.17, p<0.001)和精神病警告(使用者:B= - 0.65, p<0.05;非使用者:B= - 0.71, p<0.05)比驾驶警告更不可信,但表明他们从精神病警告中学到了比驾驶警告更多的东西(使用者:B=0.88, p<0.01;非使用者(B=1.60, p<0.001)。看到任何警告的参与者认为吸食大麻比没有看到警告的参与者更有害(均p<0.05)。精神病警告最常被选为劝阻青少年使用的最佳警告。警告具有教育消费者和影响大麻危害认知的潜力。警告在不同的产品类型中具有相似的效果,可能消除了对特定于产品类型的警告的需要。大麻使用与精神病风险的关联,是加拿大警告中提到的一个主题,可能对美国警告的重点主题有用。
Cannabis warning labels can communicate risks, but there is little research on warning perceptions and differences by product type. In a 2019 online survey, 1,000 U.S. adults (500 cannabis users and 500 cannabis non-users who used tobacco) were randomly assigned to view no warning or one of four U.S. or Canadian warnings displayed on images of packaging for dried flower or edible cannabis. The warnings described cannabis risks related to psychosis, addiction, lack of FDA oversight, and impaired driving. We used linear regression to examine perceptions of warnings and product harm as a function of product type (dried or edible) and warning. We examined which warning participants selected as most effective for discouraging youth use and impaired driving. Participants found the addiction warning (cannabis users: B=−1.04, p<0.001; cannabis non-users: B= 1.17, p<0.001) and psychosis warning (users: B=−0.65, p<0.05; non-users: B=−0.71, p<0.05) less believable than the driving warning but indicated that they learned more from the psychosis warning than the driving warning (users: B=0.88, p<0.01; non-users (B=1.60, p<0.001). Participants viewing any warning considered smoking cannabis to be more harmful than those viewing no warning (all p<0.05). The psychosis warning was most frequently selected as the best warning for discouraging youth use. Warnings have the potential to educate consumers and impact cannabis harm perceptions. Warnings have similar effects across product types, potentially eliminating the need for product type-specific warnings. The association of cannabis use with risk for psychosis, a topic addressed in Canadian warnings, could be a useful in topic of focus U.S. warnings.
