THE EFFECT OF MARIHUANA DOSAGE ON DRIVER PERFORMANCE

PERFORMANCE IN A COMPLEX DRIVING SIMULATOR UNDER 4 MARIHUANA DOSE LEVELS WAS EXAMINED. CAR CONTROL AND TRACKING APPEARED TO BE UNINFLUENCED, BUT SIGNIFICANT DOSE-RELATED IMPAIRMENT WAS FOUND ON A VISUAL RECOGNITION TASK SIMULATING THE SEARCH-AND-RECOGNITION ASPECTS OF DRIVING. AN ADDITIONAL STUDY OF SENSORY SIGNAL DETECTION SUPPORTED THE VIEW THAT THE PERCEPTUAL DEFICIT INDUCED BY MARIHUANA INVOLVES A DECREASE IN DISCRIMINATION SENSITIVITY. /HSRI/
