Great job to the founders, awesome to see more cool companies out of the UW nano program.
Curious why all the negativity, perhaps people are unaware that cannabis actively DOES impair driving to dangerous levels. Also, as this startup is from Canada I'm almost certain the mindframe of the founders is to develop a device that makes legalization EASIER, not allowing police to use it catch and arrest people on the street who they think are high.
One issue we have been dealing with in Canada is how to regulate driving after consuming cannabis. A zero tolerance policy for smoking + driving within days is unreasonable and thus will be ineffective. This device and the research behind it looks like could help regulators and police catch people who are dangerously high while not arresting those who happened to smoke much earlier.

- robocat 7y ago"Epidemiological studies have been inconclusive regarding whether cannabis use causes an increased risk of accidents; in contrast, unanimity exists that alcohol use increases crash risk" - direct quote from your link. That study is about alcohol combined with cannabis (i.e. presuming effect then striving to find a cause). Disclaimer: I have never been a cannabis user.
- nullstyle 7y ago"marijuana smokers tend to compensate effectively for their impairment by utilizing a variety of behavioral strategies such as driving more slowly, passing less, and leaving more space between themselves and cars in front of them."
- realshowbiz 7y ago“ In seven of ten studies cited, cannabis use was associated with a decrease in driving speed despite explicit instructions to maintain a particular speed, whereas under the influence of alcohol, subjects consistently drove faster. Two simulator studies showed that the tendency to overtake was decreased with cannabis use but increased with alcohol.52, 53 One simulator study and two on-road studies examining car-following behavior concluded that cannabis smokers tend to increase the distance between themselves and the car in front of them.41, 45 Other studies have found no adverse effects of marijuana use on sign detection,49 a sudden lane-changing task,43 or the detection of and response to hazardous events.”

- derekdahmer 7y agoHere is a good overview of dozens of studies that have performed on subject. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2722956/#S3title https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2722956/#S3titl... The tl;dr is Cannabis absolutely impairs the core skills you use when driving, but also raises your awareness of your impairment so those under the influence tend to drive more cautiously. The result is in simulator studies cannabis shows a clear negative effect, but in functional studies, its more of a wash.
- computerex 7y agoPlease fully read and understand the resource you linked > Experienced smokers who drive on a set course show almost no functional impairment under the influence of marijuana, except when it is combined with alcohol. And the conclusion that the lack of functional impairment is due to increased awareness of impairment is merely speculation and is not based on any empirical result.
