Results from a McGill University study on cannabis use and driving suggest young Canadians are more at risk of a vehicle crash even after inhaling marijuana several hours earlier.
45 individuals between 18 and 24-years-old who use cannabis no more than 4 times per week participated in a driving simulation and a Useful Field of View test over 4 different days.
The study’s lead author, Dr. Tatiana Ogourtsova, says the tests were done 1 hour, 3 hours and 5 hours after consuming 100 milligrams of dried cannabis flowers containing 13 percent THC.
The results indicated the driving performance of all the participants declined significantly as soon as they were exposed to distractions common in everyday driving.
Dr. Ogourtsova also says after testing, a large percentage of the young drivers reported feeling less safe and less able to drive.
“The results of this study need to be also interpreted with caution and cannot really be generalized…such as chronic cannabis users or medicinal cannabis users and also older adults where we do think that there will be quite different findings from this particular study.” she emphasized.
