Abstract
This is a review of available literature relevant to narcotic drug use and driver safety. No studies were found that directly assessed driver capability either in driving simulators or actual driving conditions. There are some studies of illegal users' driving records, including interviews with methadone treated ex-heroin addicts, and laboratory studies of effects of narcotics on skills related to driving. The weight of evidence from available studies indicates that narcotic users do not have driving safety records that differ from age matched individuals in the general population. Furthermore maintenance on methadone (a synthetic narcotic used to treat heroin addicts) does not provide a risk for driving.
