What are the effects of marijuana on driving behavior?
While we would expect that the intoxicating effects of marijuana would negatively affect driving behavior (altered perception, altered judgment, etc.), this subject has been incompletely studied. Limited studies even suggest that marijuana can cause more careful (!) driving. This is very characteristic of marijuana research. Opposing studies often cancel one another out, or there is a perception of research bias. Only an extraordinary emphasis on a large number of excellent studies on marijuana pharmacology and toxicology will help us out of this “marijuana facts vacuum”.
