背景资料：鉴于大麻使用和酒后驾车（DUI）的增加，确定那些处于风险中的人以告知干预工作至关重要。目的：我们使用了一个社会生态学框架来研究过去一个月年轻成年大麻使用者中大麻使用水平和DUI的相关性。研究方法：我们在2014年8月通过针对烟草和大麻用户的Facebook广告招募了1567名年龄在18 - 34岁之间的参与者，以完成一项在线调查，评估大麻使用和DUI以及相关的多层次因素。分析的重点是649名参与者报告过去30天的大麻使用。结果如下：样本的平均年龄为24.48岁（SD = 5.10），43.9%的女性和76.4%的白色，在过去一个月内平均使用大麻17.86天（SD = 11.29）。值得注意的是，48.4%的人报告在过去一个月内至少使用过一次大麻后开车，74.0%的人是乘客。多变量回归分析表明，更多的使用与以下因素有关：年龄较大;男性;依赖症状更严重;居住在娱乐性大麻合法化的州;拥有医用大麻卡;有父母和更多的朋友使用;更高的应对动机;对健康的伤害更低;以及对大麻使用后驾驶的关注较少（调整后的R平方= 0.294）。在过去的一个月里，使用大麻后驾驶的相关因素包括：更年轻;更频繁的使用;有更多的朋友使用;更高的增强动机;以及对使用后驾驶的担忧较少（Nagelkerke R平方= 0.442）。结论/重要性：干预措施和宣传活动应解决有关大麻使用的社会规范和风险观念，特别是与酒后驾车有关的问题。
Background: Given increases in marijuana use and driving under the influence (DUI), it is critical to identify those at risk in order to inform intervention efforts. Objectives: We used a socioecological framework to examine correlates of level of marijuana use and DUI in the past month among young adult marijuana users. Methods: We recruited 1567 participants aged 18-34years via Facebook ads targeting tobacco and marijuana users in August 2014 to complete an online survey assessing marijuana use and DUI, as well as related multilevel factors. Analyses focused on 649 participants reporting past 30-day marijuana use. Results: The sample was an average age of 24.48 (SD = 5.10), 43.9% female, and 76.4% White and used marijuana an average of 17.86 (SD = 11.29) days in the past month. Notably, 48.4% reported driving after marijuana use at least once in the past month, and 74.0% were passengers. Multivariable regression indicated that greater use was associated with: being older; being male; greater symptoms of dependence; residing in a state with recreational marijuana legalized; having a medical marijuana card; having parents and more friends who use; higher coping motives; lower perceived harm to health; and less concern about driving after marijuana use (adjusted R-squared = 0.294). Correlates of driving after using marijuana in the past month included: being younger; more frequent use; having more friends who use; higher enhancement motives; and less concern about driving after using (Nagelkerke R-squared = 0.442). Conclusions/Importance: Interventions and campaigns should address social norms and risk perceptions regarding marijuana use, particularly as it relates to DUI.
