I shouldn't even bother but I will. You apparently have a hard time telling the difference between opinions and facts. It is your opinion that cannabis has caused less traffic fatalities, but that is not a fact.

Traffic fatalities have been on a downward trend since the 70's. Partly due to a decrease in drunk driving, partly due to increase in vehicle safety, partly due to an increase in traffic control engineering and partly due to an increase in public appreciation for the dangers of driving. Looking a one state, in one year, of an overall trend is disingenuous at best, or at worst outright manipulation. It's the same bullshit the NRA tried to pull saying that Australia had a massive increase in violent crimes after banning guns. They used on city over one year, outright manipulation, just like your theory.

Here is a listing showing a roughly 40% decrease in deaths in Missouri over 8 years, hardly a bastion of cannabis legalization. How do you explain this?
I don't think you realize how precarious the legalization movement still is right now. One high profile accident where a driver only on cannabis plows into a rich white family with young kids or something could potentially push back the whole movement.
Driving is a privilege, not a right. So go ahead and drive around impaired. Then you can come back in here bitching about the mean old cops who arrested you for driving impaired, sans several thousand dollars.
It's this type of narcissistic selfishness that still holds back the legalization movement.
Now excuse me, I'm gonna go eat some C99 edibles and WALK, like a sensible fucking adult who respects the rights of others, and their body.
