To assess, before legalization in Canada, whether parental cannabis use is associated with initiation of use in adolescent offspring or with use in young-adult offspring.
Data were available in 2 longitudinal studies in Montréal, Canada. In AdoQuest, 1048 parents with children in grade 6 reported past-year cannabis use. Cannabis initiation among offspring was measured in grade 7, 9, and/or 11. In the Nicotine Dependence in Teens study, cannabis use data were available for 584 participants (mean age 24 years) and their parents (ie, 542 offspring-mother pairs, 438 offspring-father pairs). The association between parental and offspring cannabis use was estimated using multivariable logistic regression in both studies.
In AdoQuest, grade 6 never-users were 1.8 times more likely to initiate cannabis during high school if their parents reported past-year use. In the Nicotine Dependence in Teens study, the aORs (95% CI) for past-year cannabis use among adult offspring were not different for "mother uses cannabis" (2.8 [1.4-5.8]) or "father uses cannabis" (2.1 [1.2-3.8]). Participants with 1 or 2 cannabis-using parents were 1.7 and 7.1 times more likely to use cannabis, respectively, than participants with non-using parents.
To enable informed decision-making about their own cannabis use, parents need to be aware that children of cannabis users are more likely to use cannabis in adolescence and young adulthood.
在加拿大合法化之前，评估父母吸食大麻是否与青少年子女开始使用大麻有关，或与年轻成人子女使用大麻有关。
加拿大蒙特利尔的两项纵向研究提供了数据。在 AdoQuest 中，1048 名有六年级孩子的父母报告了过去一年的大麻使用情况。在 7、9 和/或 11 年级测量了子女的大麻初用情况。在青少年尼古丁依赖研究中，584 名参与者（平均年龄 24 岁）及其父母（即 542 对子女-母亲、438 对子女-父亲）提供了大麻使用数据。在这两项研究中，均使用多变量逻辑回归估计父母和子女之间大麻使用的关联。
在 AdoQuest 中，六年级从未使用者如果其父母报告过去一年使用过大麻，则在高中期间开始使用大麻的可能性是未使用者的 1.8 倍。在青少年尼古丁依赖研究中，成年子女过去一年大麻使用的比值比（95%CI）对于“母亲使用大麻”（2.8 [1.4-5.8]）或“父亲使用大麻”（2.1 [1.2-3.8]）没有差异。有 1 位或 2 位大麻使用者父母的子女使用大麻的可能性分别是无使用者父母子女的 1.7 倍和 7.1 倍。
为了能够就自己的大麻使用做出明智的决策，父母需要意识到，使用大麻的子女在青少年和年轻成人时期更有可能使用大麻。
