MARIJUANA AND ACTUAL DRIVING PERFORMANCE
National Technical Information Service
5301 Shawnee Road
The report concerns the effects of marijuana smoking on actual driving performance. The major objectives of the program were to determine the dose-response relationship between delta 9-tetrahydrocannabinol (THC), marijuana's main constituent, and objectively and subjectively measured aspects of real-world driving; and, to determine whether it is possible to correlate driving performance impairment with plasma concentrations of the drug or a metabolite. A variety of driving tests were employed, including: maintenance of a constant speed and lateral position during uninterrupted highway travel, following a leading car with varying speed on a highway, and city driving. The purpose of applying different tests was to determine whether similar changes in performance under the influence of THC occur in all, thereby indicating a general drug effect on driving ability.
