Samenvatting
Driving records of 302 persons arrested for illegal drug use were compared with 687, 228 driving records of persons living in the same driving environment. Three groups of illegal drug users were studied: 1- narcotic users; 2- dangerous drug users; and 3- marihuana users. Accident and violation rates for each group were higher, some statistically higher, than those for comparable population groups. Considerably fewer of the illegal drug users had driving records clear of violations and accidents.
