DMV, CHP & CMCR begin novel, on-road study to examine cannabis-impaired driving

The California Department of Motor Vehicles (DMV) is collaborating with the California Highway Patrol (CHP) and the Center for Medicinal Cannabis Research (CMCR) to conduct a study in which participants will smoke THC or placebo and then drive an automobile along a test track in Sacramento. A trained law enforcement officer will subsequently evaluate them for impairment. Click HERE to learn more about the study.
