Q&A - Drug Use a Concern if Cannabis is Legalized
This study was conducted in seven major trauma centers in British Columbia between 2010 and 2012.
Alcohol, cannabis and a broad range of other impairing drugs are commonly detected in injured drivers. Alcohol is well known to cause crashes, but further research is needed to determine the impact of other drug use, including drug – alcohol and drug – drug combinations, on crash risk. In particular, more work is needed to understand the role of medications in causing crashes to guide driver education programmes and improve public safety.
