Cannabis Users Showed Distinct Patterns in How They Assess Impairment and Plan Safe Transportation

Cannabis users showed substantial heterogeneity in self-regulation processes related to driving. Subgroups differed in how they perceived risks, monitored their impairment, and planned to avoid driving under the influence. These patterns varied by user characteristics and use contexts.

Survey-based study identifying subgroups of current and past cannabis users based on three self-regulation domains: risk perception, impairment monitoring, and safe transportation planning. Latent class or cluster analysis identified distinct user profiles.

One-size-fits-all approaches to cannabis-impaired driving may be ineffective because users vary dramatically in their self-regulation behaviors. Targeted interventions could address specific deficits in risk assessment or planning.

Most impaired driving interventions assume uniform behavior among cannabis users. This study's identification of distinct self-regulation profiles suggests that prevention messaging and policy should be tailored to different user types.
