Medical Cannabis, Safety-Sensitive Occupations and Driving Privileges

Health Canada has stated that “using cannabis or any cannabis product can impair your concentration, your ability to think and make decisions, and your reaction time and coordination. This can affect your motor skills, including your ability to drive. It can also increase anxiety and cause panic attacks, and in some cases cause paranoia and hallucinations.” (http://www.hc-sc.gc.ca/dhp-mps/marihuana/info/cons-eng.php)

“Although no studies have been carried out to date examining the effects of cannabis or psychoactive cannabinoid exposure on psychomotor performance in individuals using these substances solely for medical purposes, it is well known that exposure to such substances impairs psychomotor performance and patients must be warned not to drive or operate complex machinery after smoking or eating cannabis or consuming psychoactive cannabinoid medications (e.g. dronabinol, nabilone, nabiximols).” (http://www.hc-sc.gc.ca/dhp-mps/marihuana/med/infoprof-eng.php#chp771)
