People are already doing this. But fyi most people who drive under the influence of cannabis can drive perfectly fine. It's not like alcohol.
Anyways, I really doubt this will pass.
Not the most pressing issue, but making it widely available to an already irresponsible population isn't going to make it any better. I understand people already doing this but legalizing it just makes it more prevalent, and if you didn't noticed we passed a hands-free law because drivers are already inattentive to the road, don't need one more thing hindering their inability to drive.
