Stop hating on alcohol
You shouldn't smoke pot if you're that much of a tool, when you're THAT high to drive. I don't care how drunk I've ever been, or how stoned, I can still tell 'stupid' from 'don't even freaking go there'.
If you can handle your weed, and wanna drive.. Go for it, but only you can accept the blame..
In school, they bullshit you about weed, telling you it's the be all and end all of life if you start it.. That you automatically go on to harder drugs and get HIV and die.. Doesn't work like that. Just keep your sense, and don't let it progress.. Easy.
