Large CMCR study published in JAMA Psychiatry provides insights into performance and safety perception issues regarding cannabis and driving
In the largest study of its kind - 191 regular cannabis users who smoked as they “would at home to get high” - published in JAMA Psychiatry, this CMCR randomized trial examined the magnitude and time course of driving impairments due to acute cannabis use, and whether different THC content levels in cigarettes affect driving performance. The authors also report on whether a person’s use history and the development of behavioral tolerance results in less of a driving decrement, as well as whether users are accurate in self-evaluating whether they are safe to drive.
