Seems to me that this discussion has way too variables, for either side to prevail. it really doesn't matter if a person smokes a blunt or has a cocktail, if they are intoxicated, it's against the law. Doesn't matter if a drunk person is more intoxicated than a person that's high, they're both not %100. To say that a stoned person driving a prius is less dangerous that a stoned driver behind the wheel of bus at full capacity is not right. That same prius driver could easily jump a curb, kill you, your spouse and children just as easily as bus. The only differance is with a car you might get to have an open casket.
i can see your point Psychochik about you rather dealing with a person that is stoned as opposed to being drunk, and i agree, but they are still intoxicated in one way or another. I for one think that any person operating anything should not be under influence of any drug, better to be safe than sorry right.
