Cannabis effects on driving lateral control with and without alcohol

Highlights
•We model cannabis’ effects on driving lateral control via sophisticated simulator.
•Models are based on blood THC and breath alcohol concentrations during driving.
•THC increased standard deviation of lateral position (SDLP); 0.26 cm per μg/L THC.
•Alcohol increased SDLP 0.42 cm per 0.01 g/210 L; additional lateral control measures.
•During-drive 7–10 μg/L blood THC produced similar SDLP to 0.05 g/210 L breath alcohol.
•Concurrent alcohol and cannabis produced additive rather than synergistic effects.
