Cannabis use in the United States is increasing and research is needed to understand factors contributing to decisions to use. Features of cannabis product labels communicating product content may influence health perceptions and willingness to use.
We tested how individuals who use cannabis respond to different cannabinoid content and the inclusion of a visual aid to communicate cannabinoid potency.
We used a 3 (within-subjects: THC-dominant, CBD-dominant, and equal THC:CBD ratio) × 2 (between-subjects: numeric information vs numeric information plus visual aid) mixed experimental design administered online through Prolific.com. Participants (N = 431) evaluated cannabis product packages on perceived health harms and benefits and likelihood to purchase and use cannabis.
Relative to other products, CBD-dominant products were evaluated as least harmful, most beneficial, and least likely to purchase or use (all Ps < 005; ds 0.10-0.68) while THC-dominant products were evaluated as most harmful, least beneficial, and most likely to purchase and use (all Ps < .02; ds 0.11-0.68). Perceptions did not vary based on the inclusion of a visual aid (Ps > .10). In a parallel mediation model, cannabinoid content was indirectly associated with likelihood to use through perceived benefits (b = -.14, CI = -.22, -.07) but not perceived harms (b = -.01, CI = -.04, .07).
Communicating about cannabinoid content could have intended and unintended consequences. Cannabinoid content contributed to product health perceptions and willingness to purchase and use; visual depictions of cannabinoid content did not. Perceived benefits of cannabis could be a valuable intervention target to reduce potential harm.
美国大麻使用呈上升趋势，需要开展研究以了解影响使用决策的因素。传达产品成分的大麻产品标签特征可能会影响健康认知和使用意愿。
我们测试了大麻使用者对不同大麻素含量以及包含传达大麻素效力的视觉辅助工具的反应。
我们采用了一个3（被试内：以四氢大麻酚为主、以大麻二酚为主、四氢大麻酚与大麻二酚比例相等）×2（被试间：数字信息与数字信息加视觉辅助工具）的混合实验设计，通过Prolific.com在线进行。参与者（N = 431）对大麻产品包装的健康危害和益处感知以及购买和使用大麻的可能性进行了评估。
相对于其他产品，以大麻二酚为主的产品被评估为危害最小、益处最大且购买或使用可能性最小（所有P值<0.05；d值为0.10 - 0.68），而以四氢大麻酚为主的产品被评估为危害最大、益处最小且购买和使用可能性最大（所有P值<0.02；d值为0.11 - 0.68）。基于是否包含视觉辅助工具，认知没有差异（P值>.10）。在一个平行中介模型中，大麻素含量通过感知益处与使用可能性间接相关（b = -0.14，CI = -0.22，-0.07），但与感知危害无关（b = -0.01，CI = -0.04，0.07）。
传达大麻素含量可能会产生有意和无意的后果。大麻素含量影响了产品健康认知以及购买和使用意愿；大麻素含量的视觉呈现则没有。大麻的感知益处可能是减少潜在危害的一个有价值的干预目标。
