As cannabis increasingly becomes a consumer product in the U.S., its product packaging has become critically important to regulators. This study examined the influence of recreational cannabis packaging characteristics.
Five online between-subjects experiments were conducted in April 2021, and data were analyzed in May 2021-July 2021. Experiments randomized participants to view different (1) types of cannabis, (2) visual displays of tetrahydrocannabinol content, (3) cannabis packages designed around brand personality research, (4) health warnings, and (5) health claims. Outcomes included cognitive, affective, and behavioral responses.
A total of 841 adults from the U.S. (49% male, 50% young adults, 44% White, 17% Hispanic) were included in the study. Edible gummies were perceived as healthier (β=0.32, 95% CI=0.03, 0.62), less grown up (β= -0.58, 95% CI= -0.86, -0.28), and more socially acceptable to consume (β=0.30, 95% CI=0.01, 0.59) than cannabis concentrate in a medical dropper. Participants also had more interest in trying edible gummies (β=1.33, 95% CI=1.04, 1.62) and trying a free sample (β=1.30, 95% CI=1.01, 1.60) than trying cannabis concentrate. Cannabis packages with a helps-you-relax health claim elicited more happy (β=0.34, 95% CI=0.04, 0.64) and good (β=0.37, 95% CI=0.07, 0.67) feelings than cannabis packages without this claim. Minimal effects were found for visual displays of tetrahydrocannabinol content and health warnings.
Edibles are a unique type of cannabis that should be given special consideration under state laws, and lawmakers should consider limiting and governing the use of both implicit and explicit health claims on recreational cannabis packages when implementing laws.
随着大麻在美国日益成为一种消费品，其产品包装对监管机构来说变得至关重要。本研究考察了娱乐用大麻包装特点的影响。
2021 年 4 月进行了五项在线组间实验，并于 2021 年 5 月至 7 月分析数据。实验将参与者随机分配到以下不同的组别：（1）不同类型的大麻；（2）四氢大麻酚含量的视觉显示；（3）根据品牌个性研究设计的大麻包装；（4）健康警告；（5）健康声明。结果包括认知、情感和行为反应。
共有 841 名来自美国的成年人（49%为男性，50%为年轻人，44%为白人，17%为西班牙裔）参与了这项研究。食用软糖被认为更健康（β=0.32，95%置信区间=0.03，0.62）、更不成熟（β= -0.58，95%置信区间= -0.86，-0.28）、更易被社会接受（β=0.30，95%置信区间=0.01，0.59），而医用滴管中的大麻浓缩物则被认为更健康。与尝试大麻浓缩物相比，参与者也更有兴趣尝试食用软糖（β=1.33，95%置信区间=1.04，1.62）和尝试免费样品（β=1.30，95%置信区间=1.01，1.60）。带有“帮助您放松”健康声明的大麻包装比没有此类声明的大麻包装更容易让人产生快乐（β=0.34，95%置信区间=0.04，0.64）和良好（β=0.37，95%置信区间=0.07，0.67）的感觉。对于四氢大麻酚含量的视觉显示和健康警告，只发现了微小的影响。
食用大麻是一种独特的大麻类型，州法律应该特别考虑，立法者在实施法律时，应考虑限制和规范娱乐用大麻包装上的隐含和明确健康声明的使用。
