Why wouldn’t they? What, are they afraid? And that would make the municipalities complicit.
Again, I dare them. If it a straw man, then they have nothing to lose, correct?
But I have to ask again “Why would they”?
If it is used in moderation by responsible people, or for some medicinal purpose, then they are perfectly in the clear. From what I’ve read, most people busted for it are busted at home for growing it, not in the operation of a vehicle, or just having it on their person.
It isnt their responsibility to vouch for everyone that may use it, and then do something illegal or dangerous or use it to excess anymore than the cigarette makers, alcohol producers, or the people that make Tylenol. Are kind of asking them to take on a liability voluntarily?
