There was a case in Cedar Rapids, Ia as of late - where a driver ran down a female pedestrian and killed her, after his arrest - he tested positive for Cannabis. He now awaits trial on vehicular homicide charges.
I have to ask when the test materials (blood, urine, etc...) were taken from the driver. To the best of my knowledge, if it was not blood taken right with in a few hours, the positive result means squat as it pertains to his impermanent at the time of running down the pedestrian. I know courts differ on this, but the courts are forums of law, not of fact. Was the result quantified, or just qualitatively determined? The metabolites of Cannabis sp. consumption can be found in the urine of one who uses plant for weeks after consumption has stopped, with detectable levels dropping over time.
There sense of time is altered, hence the reaction time is impaired, depth perception is impaired, your attention span while driving is less after using cannabis.
Not according to the studies I've seen, such as
this one, this one and one done by the California Highway Patrol years ago that reached the same conclusions. As others have noted, drivers who are under the influence of THC alone are more cautious and focused drivers and as a whole have fewer accidents than drivers who are under the normal distractions that occur while driving.
Your first hand experiences and perceptions likely differ 12-34hom, but I expect that since I doubt you pull over all the folks who are driving about while stoned. I don't condone such, any more than I condone driving about while exhausted and sleep deprived. I would like to know more about the methodology you use to field test drivers for suspicion of Cannabis intoxication.
As far as the chap who is now serving 55 years in prison for exercising his God given/inherent right to possess the means and tools of self defense. His sentence is a grave miscarriage of justice. Keeping and bearing arms is a protected right, and "...shall not be infringed." means exactly that, and does NOT mean "except while possing this common weed, etc, etc, etc..."
But I'd best stop before this turns into a rant about our entire Judicial System.
