Lots of drugs are already legal. You probably have some in your medicine cabinet. Some of them are possibly the very same drugs that other people are in prison for possessing.

If you use those drugs in a manner that causes harm to others, your actions should be punished. There are plenty of laws that punish wrongful behavior that causes harm to others. The mere possession of a chemical is not likely to cause anyone harm.

It's much like the possession of firearms or acholic beverages. It's the behavior of the one who possesses those arms or beverages that should be regulated... not the possession in and of itself.

That don't have much to do with the baiting issue and legislating ethics though, does it?
