Diverse patterns of life-course marijuana use may have differential health impacts for the children of users. Data are drawn from an intergenerational study of 426 families that included a parent, their oldest biological child, and (where appropriate) another caregiver who were interviewed 10 times from 2002 to 2018; the current study used data from 380 families in waves 6-10. Analyses linked parent marijuana use trajectories estimated in a previous publication (Epstein et al., 2015) to child marijuana, alcohol, and nicotine use; promarijuana norms; internalizing; externalizing; attention problems; and grades using multilevel modeling among children ages 6 to 21. Four trajectories had been found in the previous study: nonuser, chronic, adolescent-limited, and late-onset. Results indicate that children of parents in the groups that initiated marijuana use in adolescence (chronic and adolescent-limited) were most likely to use substances. Children of parents in the late-onset group, where parents initiated use in young adulthood, were not at increased risk for substance use but were more likely to have attention problems and lower grades. Results held when parent current marijuana use was added to the models. Implications of this work highlight the importance of considering both current use and use history in intergenerational transmission of marijuana use, and the need to address parent use history in family based prevention. Prevention of adolescent marijuana use remains a priority. (PsycInfo Database Record (c) 2020 APA, all rights reserved).
不同模式的终生大麻使用可能对使用者的子女产生不同的健康影响。这些数据来自一项代际研究，该研究共涉及 426 个家庭，包括父母、他们的最大的亲生子女以及（在适当情况下）另一位照顾者，这些家庭从 2002 年到 2018 年接受了 10 次访谈；本研究使用了第 6 至第 10 波中 380 个家庭的数据。分析将之前发表的一项研究（Epstein 等人，2015）中估计的父母大麻使用轨迹与孩子的大麻、酒精和尼古丁使用情况；亲大麻规范；内化问题；外化问题；注意力问题以及 6 至 21 岁儿童的成绩联系起来，这些分析使用多层模型在儿童中进行。在之前的研究中发现了四种轨迹：非使用者、慢性使用者、青少年限制使用者和晚期使用者。结果表明，父母为青少年期开始使用大麻的组（慢性和青少年限制）的孩子最有可能使用物质。在父母开始在成年早期使用大麻的晚发组中，父母的孩子没有更高的物质使用风险，但更有可能出现注意力问题和成绩下降。当将父母当前的大麻使用添加到模型中时，结果仍然成立。这项工作的意义在于强调在大麻使用的代际传递中，既要考虑当前使用情况，也要考虑使用历史，并且需要在家庭预防中解决父母的使用历史。预防青少年大麻使用仍然是当务之急。（PsycInfo 数据库记录（c）2020 APA，保留所有权利）。
