"It ain't what they call you, it's what you answer to." - W. C. Fields
If anything, legalizing it will only lead to the tightening of restrictions and more regulation over people driving while high. And the development of better field tests to determine when someone is currently high as opposed to just having residual levels in their system from recreational use. IOW, we'd start to learn about, and educate people about, when they are too high to drive, and when they have come down enough to be safe. Just like we did with booze.
Ugh, why are we still discussing this? OF COURSE it should be legal. It's wasteful and just plain stupid to try to prevent people from using it. I'm so proud of my state for having this issue on the ballot this year. I sincerely hope this passes.
