Limited research has evaluated the impact of cannabis policies on young adult cannabis use, after full implementation (retail outlets opened), nor on cannabis product type. This study examined the relationship between adult-use cannabis retail sales in New Jersey (United States) and young adult cannabis use by type.
Data on New Jersey young adults (18-23 years) were from the Policy Communication and Evaluation (PACE) New Jersey Study. Generalized estimating equations models estimated differences in prevalence of ever and past 30-day use of cannabis and sub-types before (Waves 1-3 [March-November 2021], n = 1439) and after (Wave 4 [June-July 2022], n = 1127) adult-use retail sales began.
Ever cannabis use among New Jersey young adults was higher in the post-retail sales period than pre-sales (58.1 % vs. 48.9 %, p < 0.01). The odds of ever cannabis use were 42 % higher (95 % CI = 32 %-54 %) in the post-retail period. Ever use of dried herb (post vs. pre: 44.4 % vs. 38.5 %, p < 0.01), drinks (7.0 % vs. 4.8 %, p < 0.01), edibles (45.9 % vs. 35.6 %, p < 0.01), and topicals (6.4 % vs. 4.6 %, p < 0.05), and past 30-day edible use (11.8 % vs. 9.0 %, p = 0.01) were higher post-retail; use of other product types did not differ.
Cannabis use overall and among certain subtypes (e.g., edibles) increased among New Jersey young adults in the three months after adult-use cannabis retail sales began, demonstrating that increased access to legal cannabis for sale may encourage use. Continued monitoring is needed over longer follow-up periods in New Jersey and other states legalizing cannabis.
在全面实施（零售商店开业）后，针对大麻政策对年轻成年人使用大麻的影响以及对大麻产品类型的影响，相关研究有限。本研究调查了美国新泽西州成人用大麻零售与不同类型年轻成年人使用大麻之间的关系。
新泽西州年轻成年人（18 - 23岁）的数据来自新泽西政策沟通与评估（PACE）研究。广义估计方程模型估计了成人用大麻零售开始之前（第1 - 3波[2021年3月 - 11月]，n = 1439）和之后（第4波[2022年6月 - 7月]，n = 1127）大麻及亚型的曾经使用和过去30天内使用流行率的差异。
新泽西州年轻成年人中，零售销售期后曾经使用大麻的比例高于销售前（58.1%对48.9%，p < 0.01）。零售期后曾经使用大麻的几率高出42%（95%置信区间 = 32% - 54%）。零售后，曾经使用干草药（后对前：44.4%对38.5%，p < 0.01）、饮料（7.0%对4.8%，p < 0.01）、 edibles（45.9%对35.6%，p < 0.01）和外用剂（6.4%对4.6%，p < 0.05）以及过去30天内食用型大麻使用（11.8%对9.0%，p = 0.01）均有所增加；其他产品类型的使用无差异。
在成人用大麻零售销售开始后的三个月里，新泽西州年轻成年人总体及某些亚型（如食用型大麻）的大麻使用有所增加，表明合法销售的大麻获取增加可能会鼓励使用。新泽西州及其他大麻合法化的州需要在更长的随访期内持续监测。
