Prevalence of Impairing Substance Use in Injured Drivers.

ABSTRACT:

Importance

Impaired driving is an important public health issue, but its prevalence is challenging to monitor.

Objectives

To report the prevalence of alcohol, cannabis, recreational drugs, and sedating medications in injured Canadian drivers, identify demographic and collision factors associated with drug or alcohol use, and compare the prevalence of drug-involved driving in different parts of Canada.

Design, setting, and participants

This cross-sectional study prospectively obtained blood samples from injured drivers treated in 15 Canadian trauma centers and measured blood levels of tetrahydrocannabinol (THC; the main impairing compound in cannabis), alcohol, stimulants, opioids, and depressants from January 2019 to June 2023. Data were analyzed from April to May 202
