To examine post-retail marijuana legalization (RML) change in marijuana use frequency and pro-marijuana norms among parents.
The Intergenerational Study, a longitudinal panel of parents (N = 668) and children, followed participants from 2002 to 2018, when parents were 27 and 43 years old, respectively. Three quarters of participants (74%) lived in an RML state and 142 (21%) had used marijuana in the 8 years prior to RML. Piecewise growth modelling compared pre- and post-RML slopes of use frequency and pro-marijuana norms.
Frequency of use and pro-marijuana norms increased following legalization in both RML and non-RML states, though norms rose significantly faster in RML states. Growth in use was primarily driven by new users of marijuana. There were no differences in frequency of marijuana use or pro-marijuana norms by race/ethnicity, gender, or education.
An increase in marijuana use frequency associated with RML among parents poses risk to both parents' well-being and the health of their children. A faster pace of increase in pro-marijuana norms in RML states may signal continued increases in use in the future.
研究零售大麻合法化（RML）后父母使用大麻的频率以及支持大麻的规范的变化。
代际研究是一项针对父母（N = 668）和子女的纵向面板研究，从2002年至2018年跟踪参与者，当时父母分别为27岁和43岁。四分之三的参与者（74%）生活在大麻零售合法化的州，142人（21%）在大麻零售合法化前的8年中使用过大麻。分段增长模型比较了大麻零售合法化前后使用频率和支持大麻规范的斜率。
在大麻零售合法化的州和非大麻零售合法化的州，合法化后使用频率和支持大麻的规范均有所增加，不过在大麻零售合法化的州，规范增长得明显更快。使用量的增长主要由大麻新用户推动。大麻使用频率或支持大麻的规范在种族/民族、性别或教育程度方面没有差异。
父母中与大麻零售合法化相关的大麻使用频率增加对父母的幸福以及子女的健康均构成风险。大麻零售合法化的州支持大麻规范的更快增长速度可能预示着未来使用量将持续增加。
