Other dependent variables

Almost 50% positive for drugs or alcohol, 7% positive for drugs alone

RR for those drivers involved in weekend crashes being hospitalized with a positive BAC was 1.66

Comments

Drug use was broken down by number of drivers

The numbers were small (1 – 6) and, therefore, % for each drug was not given in the paper
