2. Risks related to driving after cannabis use
This review considered two primary risks associated with driving after cannabis use: risk of motor vehicle accidents (MVA) and risks of legal penalties.
Summary and Conclusions
• The increased risk for cannabis-related motor vehicle collision currently found in the population is roughly 20-30%, with an MVA odds ratio (OR) of approximately 1.22.
• Studies that controlled for alcohol use, found the MVA OR for DACU (Driving After Cannabis Use) is 1.18; those controlling for demographic factors and alcohol found no increased risk (OR=1).
