INTERACTION BETWEEN MARIHUANA AND ETHANOL: EFFECTS ON PSYCHOMOTOR PERFORMANCE

This is a report of the results of a placebo-controlled study in which the effects of the interaction between ethanol and marihuana on drug plasma concentrations, subjective ratings of intoxication, heart rate acceleration, and psychomoter performance were investigated. The variables measured in the study were subjective rating of ethanol and marihuana intoxication; heart rate; accuracy and latency of response in the simulator evaluation of drug impairment task; blood ethanol concentration gas chromatography; and plasma concentration of the THC (delta-9-tetrahydrocannabinol) by radioimmunoassay. The results indicate that the decrements due to ethanol in performance of skills necessary to drive an automobile were significantly enhanced by marihuana in an additive and perhaps synergistic manner. The administration of ethanol prior to marihuana smoking did not produce significant effects on the subjective rating of 'high,' heart rate acceleration, or THC plasma concentration.
