Okay so what’s the answer? Legalize all drugs? Legal use where and when, what if the poor user can’t afford his/her drugs? Do we supply the users with free state approved/safe drugs at low or no cost so as to keep the crime rate down? After all we can’t have users become criminals because they can’t afford their drug of choice! How do you propose to keep from creating a new entitled class that we have to supply? I don’t have the answers but it sounds like you think you do, as they say, please enlighten me.

Just because you make something legal is no reason to involve big brother.
Impaired driving is already illegal, so no further laws are required.
