Young adults that drive after cannabis use (DACU) may not share all the same characteristics. This study aimed to identify typologies of Canadians who engage in DACU. About 910 cannabis users with a driver's license (17–35 years old) who have engaged in DACU completed an online questionnaire. Two-step cluster analysis identified four subgroups, based on driving-related behaviors, cannabis use and related problems, and psychological distress. Complementary comparative analysis among the identified subgroups was performed as external validation. The identified subgroups were: (1) frequent cannabis users who regularly DACU; (2) individuals with generalized deviance with diverse risky road behaviors and high levels of psychological distress; (3) alcohol and drug-impaired drivers who were also heavy frequent drinkers; and (4) well-adjusted youths with mild depressive-anxious symptoms. Individuals who engaged in DACU were not a homogenous group. When required, prevention and treatment need to be tailored according to the different profiles.

使用大麻后驾车的加拿大年轻人的类型：两步聚类分析

吸食大麻后开车的年轻人 (DACU) 可能不具有所有相同的特征。本研究旨在确定从事 DACU 的加拿大人的类型。大约 910 名有驾照（17-35 岁）从事 DACU 的大麻使用者完成了在线问卷调查。两步聚类分析根据与驾驶相关的行为、大麻使用和相关问题以及心理困扰确定了四个亚组。已确定的亚组之间的补充比较分析作为外部验证进行。确定的亚组是：（1）经常使用 DACU 的大麻使用者；(2) 具有多种危险道路行为和高度心理困扰的普遍偏差个体；(3) 酗酒和吸毒的司机，也是经常酗酒的人；(4) 适应良好的青少年，有轻度抑郁-焦虑症状。参与 DACU 的个人不是一个同质群体。需要时，需要根据不同的情况量身定制预防和治疗。
