abstract="Studies of the accident involvement of cannabis users have given somewhat contradictory results.  None have studied such accidents in relation to exposure.  This study investigated the frequency of driving, accident involvement, and driving charges after marijuana use among college students.  While 42% of the licensed drivers had used marijuana, only 62% of those reported driving soon after that use.  Few reported accidents or moving violations after marijuana use, especially in comparison to after alcohol use.  The frequency of marijuana driving occasions is only about 35% of alcohol driving occasions, however.  It is possible that if legislation resulted in increased exposure, marijuana would not be safer than alcohol for driving.  Keywords: Cannabis impaired driving <p />",
