I have never met stoner who said “Maybe I’m too stoned to drive”.
See the link I just posted for why enforcement is such a problem.
Doesn’t enter a lot of their minds. The local lake I fish has a good number of people that pull in, park, and get high. There’s one car I see nearly every day...probably students at the nearby college. They sit and laugh... the other day, I saw the driver open the door and pour out the bong water. After a while, they drive off.
Certainly you’ve never met with me, a daily cannabis user who will never get behind the wheel of a car while under the influence of any medications.
Still thriving as a daily user since 2015!
