Demiurge said:Marijuana is less impairing than alcohol, so while driving under its influence is irresponsible, it is less dangerous. This has been verified by studies and is more than my personal opinion.
Marijuana may be less of hazard when compared to Alcohol and other drugs, but it none the less negatively effects reaction time and motor function and should not be taken lightly.
"As with alcohol, prlonged use of marijuana seems to have a cumulative effect. This shows up as slower raction times in perceptual-motor tasks." (Varma & Malhotra, 1988).
"..decreases the speed of visual information processing." (Braff, Silverton, Saccuzzo, & Janowsky, 1981).
"..changes in depth perception and distortions in the perception of size." (Tart, 1971).
"..[the study caused] one group of experimenters to caution against night driving while under the influence of marijuana." (Sharma & Moskowitz, 1972).
