12:00 pm EDT - 1:00 pm EDT


The legal framework for recreational and medical cannabis has shifted in the last decade in many countries around the world, and still others are considering making this move. This trend has brought more urgency to the issue of cannabis-impaired driving. The science surrounding this issue is complex and studies are not easily compared nor interpreted. Many studies report mixed findings related to impairment and suffer from different limitations. As such, the implications of research findings are not easily or clearly translated into policy and legislation, which is also often informed by other factors. For this reason, the International Council on Alcohol, Drugs & Traffic Safety formed a Drugged Driving Workgroup comprised of international expert to clearly summarize the latest research findings to help inform policy decisions in many countries. This presentation will summarize some of the latest Canadian data and provide an overview of key findings from the factsheet series.
