HARTFORD — Marijuana use had little effect on simulated driving skills, according to a Hartford Hospital study, but test subjects were more easily distracted when under the influence of the drug.
Investigators from Hartford Hospital and the University of Iowa Carver College of Medicine assessed the simulated driving performance of 50 male and 35 female subjects in a double-blind, placebo-controlled trial. All 85 subjects reported having used marijuana from one to 10 times per month previously.
The study was published in the March issue of the Journal of Psychoactive Drugs.
During the study, some subjects were given actual marijuana cigarettes, and some were given a placebo, with neither the investigator nor the subject knowing which they had smoked. Another administrator kept track of who was given which type of cigarette.
