I don't need the data to know when something has the potential for danger
Respect appreciated! However, you absolutely do because you're simply wrong, and the data PROOVES that. Sleepy drivers, old drivers, and new drivers will cause more accidents than your average cannibis user. Driving with a gun in the car is a potential for danger, but there's no way you could outlaw guns in cars unless there was data to show that potential is reality.
I agree we should not keep giving chances to drunk drivers. How many drunk drivers killed someone after getting a DUI, and getting back on the road? MANY. You get caught drunk driving a vehicle in Germany, you'll never legally drive again. That's how it should be because ALCOHOL KILLS PEOPLE.
Cannibis, by all the data in the US of all car accidents, does not, and its a big issue to medical cannibis patients because of how the drug lingers, beyond its psychoactive effects. A breathalizer cannot tell you if someone is stoned, only if they have pot on their breath.
The reason it is ludicrous, and anathema, is that we have a rather large population that is prescribed drugs like Xanax (which is a good drug for those that need it, I'm just using it as an example). You think Xanax isn't abused, Xanax intoxication doesn't cause accidents? Xanax has been legal a long time... where the fuck are the Xanax breathalizers??
This singling out of cannibis by these police is rooted in racism. Really. Learn history, and you will find that your very own negative opinions have thier roots in racism. If you can live with that, ok. I cannot.
Reiterating: intoxicated driving is bad. No, we don't need to single out cannibis users with technology and spend any resources going after these offenders that cause no harm... I'm not saying they're good, I'm saying it is a tremendously poor distribution of resources to go after the least offenders the hardest.
