简介：随着越来越多的州将大麻使用合法化，大麻产业不断发展，推出了各种大麻产品。我们的研究探讨了多种大麻产品的使用（聚大麻使用）以及与这种行为相关的特征。方法：通过现有的在线小组对过去一个月的 18-34 岁大麻使用者进行了在线调查（n = 2444）。参与者回答了有关过去一个月三种类型大麻（植物大麻、浓缩大麻、食用大麻）的使用、大麻使用模式以及使用后驾驶的问题。使用潜在类别分析来识别大麻使用者的亚组。结果：确定了四类大麻使用者：轻植物使用者，他们很少使用植物性产品，并且在使用后不太可能开车（32%）；重度植物使用者，主要频繁使用植物性产品，每天多次，并且可能在使用后开车（37%）；植物和浓缩物用户大量使用植物性产品，但至少很少使用浓缩物，每天使用多次，并且可能在使用后开车（20%）；轻型植物和食品使用者，他们不经常使用这两种产品，并且在使用后不太可能开车（10%）。那些生活在合法大麻州的人更有可能属于聚大麻群体。讨论：我们的研究结果反映了新大麻产品在合法州越来越受欢迎，并表明重度吸食者群体（包括浓缩吸食者）与吸食后驾驶有关。随着各种形式的大麻使用的增加，对多种类型大麻的使用进行监测和监视对于确定对生理和社会后果的潜在不同影响非常重要。
Introduction: With more states legalizing marijuana use, the marijuana industry has grown, introducing a variety of marijuana products. Our study explores the use of multiple marijuana products (poly-marijuana use) and the characteristics associated with this behavior.Methods: Past-month marijuana users aged 18-34 years were surveyed online via an existing online panel (n = 2444). Participants answered questions about past-month use of three types of marijuana (plant-based, concentrates, edibles), marijuana use patterns, and driving after use. Latent class analysis was used to identify subgroups of marijuana users.Results: Four classes of marijuana users were identified: Light plant users, who used only plant-based products infrequently and were unlikely to drive after use (32%); Heavy plant users, who used mainly plant-based products frequently, multiple times per day, and were likely to drive after use (37%); Plant and concentrates users, who used plant-based products heavily and concentrates at least infrequently, used multiple times per day, and were likely to drive after use (20%); Light plant and edibles users, who used both products infrequently and were unlikely to drive after use (10%). Those in legal marijuana states were more likely to belong to the poly-marijuana groups.Discussion: Our findings reflect the increase in popularity of new marijuana products in legal states and suggest that heavy user groups, including concentrates users, are associated with driving after use. As various forms of marijuana use increases, monitoring and surveillance of the use of multiple types of marijuana will be important for determining potential varying impacts on physiological and social consequences.
