虽然青少年的吸烟率有所下降，但大麻的使用在这一人群中有所增加。然而，医用大麻法律（MML）和青少年吸烟之间的关联需要进一步研究。我们调查了MML与开始吸烟年龄之间的关系，并按性别、种族/民族和州药房状况对调查结果进行了分层。数据来自N= 939，725名生活在46个州的9 - 12年级青少年，他们在1991-2015年间参加了青少年风险行为监测系统。参与者被问及他们第一次吸烟的年龄和其他社会人口特征。如果各州在2015年之前将医用大麻合法化，则被归类为MML州。我们使用了差异中差异的方法和逻辑回归来评估MML和吸烟开始之间的关系。我们的研究结果表明，与非MML状态相比，MML状态下每个年龄组（8岁或以下，9-10岁，11-12岁，13-14岁，15-16岁，17岁或以上）开始吸烟的几率较低。分层后，我们发现在某些年龄组的性别，种族/民族，和国家药房状态的吸烟开始的几率较低。我们报告在每个年龄组的西班牙裔青少年中，以及8岁或8岁以下和17岁或17岁以上的黑人青少年中，州MML实施和开始吸烟的年龄没有差异。与非MML状态的青少年相比，MML状态的青少年吸烟开始减少。进一步的研究应该评估MML和娱乐性大麻政策如何与电子烟的开始和使用相关。
Although cigarette use has declined among adolescents, marijuana use has increased in subgroups of this population. The association between medical marijuana laws (MMLs) and cigarette initiation among adolescents, however, needs further examination. We investigated the association between MMLs and age of cigarette initiation and stratified findings by gender, race/ethnicity, and state dispensary status. Data were from N=939,725 adolescents in 9th-12th grade living in 46 states who participated in the Youth Risk Behavior Surveillance System between 1991–2015. Participants were asked the age they first smoked a cigarette and other sociodemographic characteristics. States were categorized as MML states if they had legalized marijuana for medicinal purposes by 2015. We used a difference-in-difference methodology and logistic regressions to assess the relationship between MMLs and cigarette initiation. Our results indicate lower odds of initiating cigarettes, in every age group (8 years old or younger, 9-10, 11-12, 13-14, 15-16, 17 years old or older) in states with MMLs when compared to non-MML states. After stratification, we find lower odds of cigarette initiation in certain age groups by gender, race/ethnicity, and state dispensary status. We report no difference in state MML implementation and age of cigarette initiation among Hispanic adolescents in every age group, and Black adolescents 8 years or younger and 17 years or older. Cigarette initiation has decreased among adolescents in MML states compared with those in non-MML states. Further research should evaluate how MMLs and recreational marijuana policies are associated with e-cigarette initiation and use.
