As (medical) cannabis legalization continues to roll out across the planet, governments have a hard time adapting to the idea of driving under the influence (DUI). And while driving under the influence should never be promoted, most governments sadly lack a basic understanding of how cannabis works. Patients are fined and losing their license, while recreational users can get positively tested days after using cannabis. Reefer Madness on the road.
Whereas governments tend to treat a cannabis DUI like an alcohol DUI, they should be treated separately for various reasons.
First and foremost should be looked whether cannabis really impairs driving. Of course, driving on cannabis after your first time consuming is never a good idea. But studies and experiments have shown cannabis use does not impair driving like alcohol does.
Physically, cannabis has been known to leave trails in your blood up to 30 days after consuming. However, you’re not going to feel high 20 days after consumption and neither will it impair your driving. As such, blood tests say very little about how impaired a driver really is.
Then, there’s the troubling case of patients whom can’t drive without cannabis. Or at least, have to consume cannabis to ensure a quality of life. Whether they are actually high while being tested, is irrelevant if they have consumed in the morning to alleviate nuisances.
Arguably the best source of cannabis and driving, the extensive study done by the Canadian Drug Policy Coalition (CDPC).
For this special on cannabis and driving, Cannabis News Network attended the the third international symposium on drug-impaired driving in Lisbon and got to speak with various experts, including: Doug Beirness (Canada, Senior Research & Policy Analyst and Advisor, Canadian Centre on Substance Use and Addiction), Jan Ramaekers (The Netherlands, Professor of Psychopharmacology and Behavioral Toxicology, Maastricht University), Brendan Hughes (EU, EMCDDA, specialist narcotics law) and Darrin Grondel (USA, Governors Highway Safety Association GHSA).
