Objectives. To characterize regulatory practices related to nonmedical cannabis warning labels in states across the United States that have legalized retail nonmedical cannabis. Methods. In March 2024, we conducted a content analysis of regulations for nonmedical cannabis warning labels required on product packages in 20 states where, as of March 2024, adults could legally purchase nonmedical cannabis in retail environments. For each state, we examined requirements related to warning label content and characteristics. Results. Required warning label content and characteristics varied widely across states. Only 2 states required a warning about mental health risks (10%) and 2 states required a warning for high potency products on risk of psychosis (10%). No states required front-of-package warning placement, only 2 states required rotating warnings (10%), and 4 states required contrasting colors (20%). Warnings were often verbose (mean = 57 words), vague, and had small or no minimum font size. Conclusions. Opportunities exist for states to improve the alignment of their nonmedical cannabis warning label regulations with evidence that has been generated so far in cannabis effects, cannabis warning efficacy, and warning label design.

2024 年美国合法零售非医用大麻的各州大麻警告标签的监管形势。


目标。描述美国各州已将零售非药用大麻合法化的州与非药用大麻警告标签相关的监管做法。方法。2024 年 3 月，我们对 20 个州的商品包装上要求使用非药用大麻警告标签的法规进行了内容分析，这些州的成年人可以在 2024 年 3 月的零售环境中合法购买非药用大麻。对于每个州，我们检查了与警告标签内容和特征相关的要求。结果。各州所需的警告标签内容和特征差异很大。只有 2 个州要求对心理健康风险发出警告 （10%），2 个州要求对高效产品发出关于精神病风险的警告 （10%）。没有州要求在包装正面放置警告，只有 2 个州要求旋转警告 （10%），4 个州要求对比色 （20%）。警告通常很冗长（平均值 = 57 个单词）、模糊不清，并且最小字体较小或没有最小字体大小。结论。各州有机会改进其非医用大麻警告标签法规与迄今为止在大麻效果、大麻警告功效和警告标签设计方面产生的证据的一致性。（美国公共卫生杂志，2024 年;114（S8）：S681-S684。https://doi.org/10.2105/AJPH.2024.307722）。
