Objectives. To examine whether local cannabis policies and retail availability are associated with cannabis use and problematic cannabis use (PCU) among adolescents in Northern California. Methods. The sample comprised adolescents aged 13 to 17 years screened for past-year cannabis use during well-child visits in 2021. Exposures included local bans on cannabis storefront retailers, policy protectiveness, and retail proximity and density. Outcomes included self-reported past-year cannabis use and PCU diagnoses. Modified Poisson regression models adjusted for sociodemographics. Results. The sample (n = 103 134) was 51.1% male with a median age of 15 years (interquartile range [IQR] = 14-16 years); 5.5% self-reported cannabis use, and 0.3% had diagnosed PCU. Adolescents had a lower prevalence of cannabis use in jurisdictions that banned storefront retailers (adjusted prevalence rate [APR] = 0.857; 95% confidence interval [CI] = 0.814, 0.903 vs allowed), banned delivery (APR = 0.751; 95% CI = 0.710, 0.795 vs allowed), or had more policy protections (APR range = 0.705-0.800). Lower PCU prevalence was also found among those in jurisdictions that banned (vs allowed) storefront retailers (APR = 0.786; 95% CI = 0.629, 0.983) or delivery (APR = 0.783; 95% CI = 0.616, 0.996). Longer drive time and lower density of storefront retailers were associated with a lower cannabis use prevalence. Conclusions. More protective cannabis policies and less retail availability were associated with a lower prevalence of adolescent cannabis use and PCU.

当地大麻政策和零售供应与北加州青少年大麻使用和有问题的大麻使用的关联。


目标。研究当地的大麻政策和零售供应是否与北加州青少年的大麻使用和有问题的大麻使用 （PCU） 有关。方法。该样本包括 13 至 17 岁的青少年，他们在 2021 年的儿童健康访视期间接受了过去一年大麻使用情况的筛查。风险包括当地对大麻店面零售商的禁令、政策保护性以及零售邻近性和密度。结局包括自我报告的过去一年的大麻使用情况和 PCU 诊断。针对社会人口统计学调整的改良泊松回归模型。结果。样本 （n = 103 134） 为 51.1% 的男性，中位年龄为 15 岁 （四分位距 [IQR] = 14-16 岁）;5.5% 的人自我报告使用大麻，0.3% 的人被诊断为 PCU。在禁止店面零售商（调整后患病率 [APR] = 0.857;95% 置信区间 [CI] = 0.814,0.903 vs 允许）、禁止送货（APR = 0.751;95% CI = 0.710,0.795 vs 允许）或有更多政策保护（APR 范围 = 0.705-0.800）的司法管辖区，青少年使用大麻的流行率较低。在禁止（与允许的）店面零售商（APR = 0.786;95% CI = 0.629,0.983）或送货（APR = 0.783;95% CI = 0.616,0.996）的司法管辖区中，PCU 患病率也较低。较长的驾驶时间和较低的店面零售商密度与较低的大麻使用率有关。结论。更多的保护性大麻政策和较少的零售可用性与青少年大麻使用和 PCU 的较低流行率有关。（美国公共卫生杂志，2024 年;114（S8）：S654-S663。https://doi.org/10.2105/AJPH.2024.307787）。
