Libertarians - if you can believe them - are the only Constitutionalists. And why not? Libertarians wrote the dang thing.
Oh. And pass that joint, man.
I’ve actually seen libertarians being more reasonable on a lot of drugs, in that a fair amount of drugs make people dangerous to others (e.g., meth).
They also always agree that private employers can have whatever rules they want regardign drugs and can fire people for drugs all day long.
