Medical cannabis is used to manage various health conditions. However, concerns about its potential impact on driving abilities persist despite repeated studies that indicate that there are no real issues with impairment. However, recent research once again confirms the effects of prescribed medical cannabis products on driving performance among patients.
A study aimed to explore this topic by evaluating the driving performance of 40 adults who consumed their prescribed medical cannabis products in a laboratory setting. The participants spanned a wide age range. They each underwent simulated driving tests before dosing, as well as at 2.5 and 5 hours post-dosing. Measurements were made of their speed, steering variability, and perceived driving effort.
The results of the study revealed several key findings. First, there was a noticeable improvement in vehicle control and adherence to speed limits among participants after they took their medication. Yes, people who were on their medicine were not impaired but were actually BETTER at driving. To people with an ounce of common sense, this conclusion may seem shocking.
This clearly demonstrates that the prescribed use of medical cannabis does not significantly impair driving abilities.
Additionally, self-reported perceived driving effort decreased after consumption. That means that participants indicated that they actually felt more comfortable and confident behind the wheel after taking their medicine. Anyone who has driven a car knows that your comfort level is as important as anything else in driving.
Interestingly, the study also compared the effects of different types of medical cannabis products. Those who consumed oil-based products exhibited slightly more weaving within their lanes, and felt less comfortable behind the wheel when compared to those using flower-based products. However, these differences were found by the authors to be relatively modest and did not indicate significant impairment.
Even the researchers did not consider this to be particularly significant, noting “Critically, no notable evidence of driving impairment (i.e. a significant decline in driving performance metrics within the simulated driving scenario) was observed for either consumption modality [oil and flower-based], relative to baseline.”
Importantly, the presence of THC in oral fluid samples was detected up to 6 hours after dosing. Despite this, the study concluded that the concentrations observed were within a range that did not substantially impact driving performance. This has important implications for saliva testing in impaired driving investigations in Canada.
Overall, this study provides valuable insights into the effects of prescribed medical cannabis on driving. It confirms yet again that when used as directed, medical cannabis containing THC has little to no impact on driving performance. Of course, if you deviate from your prescription or prescribed dose the study has little applicability to you.
