abstract="The effect of cannabis and alcohol on estimation of time and distance during simulated car driving was studied. Cannabis resin containing 4% δ1-tetrahydrocannabinol (THC) was administered orally in 3 doses equivalent to 8, 12, and 16 mg THC. Alcohol was given orally in one dose of 70 g. The subjects were 8 men, 21 to 29 years old. Cannabis showed much stronger effect than alcohol on the estimation of time and distance. The effect of cannabis was more marked on the &quot;subjective&quot; than on the &quot;objective&quot; estimation. A dose-response type of effect was seen on cannabis. © 1973 Springer-Verlag.
