How do we counter people showing up to work high as a motherfucker if medical weed is legal? I can't answer that one. And that is why they prefer pharmacy drugs. Because it cures you but still be able to function normally.

Achem, Half-Baked comes to mind.

C-mon guys, you gotta think like a cop/politician to answer your own questions!
