U of Sask. study to give people weed gummies and a driver’s test to measure impairment
In the realm of human experiments, one innovative approach stands out as a relaxed and effective way to further scientific knowledge. The Driving Research and Simulation Laboratory at the University of Saskatchewan is set to embark on a groundbreaking study in early 2025 using a cutting-edge driver simulator to explore the effects of consuming edible cannabis on individuals.
The study, led by Alexander Crizzle, the lab’s director and an associate professor of public health, aims to fill a significant gap in research by focusing on the impact of edibles, specifically 10-milligram cannabis gummies containing THC, the psychoactive compound responsible for producing a high. Participants selected for the study will spend a day in the lab after consuming the edible, undergoing tests on the driving simulator to assess their level of impairment. To ensure their safety, snacks and cab fare home will be provided.
Crizzle and his research team will evaluate impairment by observing participants’ performance on basic driving manoeuvres such as lane changes and merges. Additionally, cognitive tests will be conducted to gauge how well individuals can think and react under stress, providing valuable insights into the effects of edibles on driving ability.
The Driving Research and Simulation Laboratory has a history of conducting studies on various health and safety aspects of driving, including long-haul trucking and drivers with early onset dementia. Equipped with state-of-the-art simulators that offer a realistic driving experience, the lab’s expertise and resources attracted the interest of CAA Saskatchewan, leading to a collaboration on this pioneering project.
CAA Saskatchewan, a co-funder of the study, plans to utilize the findings in a national campaign aimed at raising awareness about the dangers of driving under the influence of cannabis. A recent poll conducted by CAA revealed an alarming trend among young drivers who believe they can drive as well or better when high, highlighting the urgent need for research to address this misconception.
With the legalization of cannabis in 2018 came new criminal offences related to impaired driving, prompting Saskatchewan to implement a zero-tolerance policy for THC in drivers’ systems. The study’s focus on edible cannabis, particularly the comparison between indica and sativa strains, will provide invaluable data on the duration and extent of impairment caused by edibles, shedding light on a relatively unexplored area of research.
Crizzle emphasized the novelty of this study, emphasizing the lack of existing research on edible cannabis and its impact on driving ability. By conducting tests at multiple intervals, the research team hopes to identify the peak moments of impairment and contribute to a better understanding of the risks associated with driving under the influence of edibles.
In conclusion, the Driving Research and Simulation Laboratory’s forthcoming study represents a significant step towards enhancing road safety and public awareness of the effects of cannabis consumption on driving performance. Through meticulous research and innovative methods, this project has the potential to shape future policies and interventions aimed at preventing impaired driving and promoting responsible cannabis use.
