背景：最近出现了一种趋势，个人使用电子尼古丁输送系统（ENDS）或类似装置以高效四氢大麻酚浓缩物或大麻植物材料的形式蒸发大麻。同伴使用是年轻人采用物质使用行为的核心，但人们对开始吸食大麻的同伴影响知之甚少。方法：采用社会网络方法对一年级大学生（N = 1313）进行纵向调查，以确定吸大麻的流行程度、开始吸大麻的个体之间的网络差异，以及两个时间点上吸大麻的预测因素。调查从每学期的第六周开始，为期两周。结果：我们发现9.4%的人在他们的一生中吸过电子烟，但自第一次调查以来没有吸过，7.5%的人在他们的一生中吸过电子烟，自第一次调查以来吸过电子烟，5.9%的人在第二次调查中报告吸食大麻。终生大麻使用、终生ENDS使用以及从第1次到第2次开始吸大麻的同龄人数量与吸大麻的几率增加显著相关；吸食大麻或使用ends的同龄人的数量与开始吸食大麻的几率增加无关。结论：在大学一年级开始吸大麻的风险最大的人是那些有其他大麻使用史和ENDS使用史的人，以及在他们的网络中有同龄人开始吸大麻。
Background: A trend has recently emerged of individuals using electronic nicotine delivery systems (ENDS) or similar devices to vaporize cannabis, either in the form of high-potency THC concentrates or cannabis plant material. Peer use is central to the adoption of substance use behaviors in young adulthood, but little is known about peer influence for initiating cannabis vaping.Methods: A longitudinal investigation of first-year college students (N = 1313) using social network methods was conducted to determine the prevalence of vaping cannabis, differences in networks between individuals who initiate vaping cannabis, and predictors of initiation of vaping cannabis across two time points. The surveys were available for two weeks beginning in the sixth week of each semester.Results: We found that 9.4% vaped in their lifetime but not since the first survey, 7.5% vaped in their lifetime and since the first survey, and 5.9% reported vaping cannabis at the second survey. Lifetime cannabis use, lifetime ENDS use, and number of peers who initiated vaping cannabis from Time 1 to Time 2 were significantly associated with increased odds of the initiation of vaping cannabis; the number of any-cannabis-using or any ENDS-using peers was not associated with increased odds of initiating vaping cannabis.Conclusions: Individuals with the greatest risk of initiation of vaping cannabis during the first year of college are those with a prior history of other cannabis use and ENDS use and who have peers in their network who initiate cannabis vaping.
