Collisions Attributable to Cannabis: Estimating the Harms and Costs in the Canadian Provinces

After alcohol, cannabis is the most widely used psychoactive substance in
Canada and cannabinoids are among the most common psychoactive
substances found in dead and injured drivers in Canada (Beasley &
Beirness, 2011; Brubacher et al., 2016). In 2012, approximately 10% of
Canadians aged 15 and older used cannabis and just under half of those
reported driving within two hours of using it (Health Canada, 2012).
However, there remains a lot that we don’t know about the extent and
costs associated with driving under the influence of cannabis (DUIC). As
Canada is poised to introduce legislation to regulate cannabis, conversations
on the harms related to cannabis and driving are becoming increasingly relevant.

Purpose
This study, “Estimating the Harms and Costs of Cannabis-Attributable Collisions in the Canadian Provinces,” is one of the first in Canada to address knowledge gaps about the costs associated with DUIC.  It estimates:
– The number of people in each province who were killed or injured in a motor vehicle collision (MVC) in which a driver was DUIC, or involved in a property-damage-only (PDO) crash in which
one of the drivers was DUIC; and
– The total economic and social costs associated with collisions in which cannabis use was involved. The study results will help to inform policies and practices aimed at reducing harms related to DUIC.

Description of the Study
To achieve these goals, data were collected from national self-report
surveys and roadside surveys. The data were used to estimate the
prevalence of DUIC by age and province.
