abstract="Blood samples, driver records and accident records of 41 female and 186 male fatally injured drivers were examined. Toxicologies showed: 37 percent alcohol-only; 11 percent alcohol-and-drugs; and 9 percent drugs-only. The most frequently found drugs were: 48 percent alcohol; 13 percent tetrahydrocannabinol or its metabolites (THC/THCCOOH); 4 percent cocaine; and 5 percent diazepam. To investigate the relationship between accident patterns and alcohol and drug use, a factor analysis of accident and driver records produced a 7-factor varimax solution accounting for 63 percent of the matrix variance. The &quot;Male Single Vehicle&quot; factor related positively to alcohol, the &quot;Young Recidivists&quot; factor related to both alcohol and THC/THCCOOH, and the &quot;Weather&quot; factor related to CNS depressants. Accidents should be examined using multivariate techniques to develop more effective accident classification systems.  Keywords: Cannabis impaired driving; DUID; Ethanol impaired driving<p />",
