Shut down the War on Drugs.
With recreational pharmaceuticals available at base production cost, those wanting to either indulge or to kill themselves would be free to so do. Drug laws are based on the premise that the citizen is property of the state and thus the state has an interest in not allowing the state property (said citizen) to be damaged by drugs.
Oh, don’t forget that laws against suicide are based on the same Royalist concept - can’t kill the King’s property.
Well - in America we are not the property of the state and neither drug laws or anti-suicide laws should have been passed.
I’m no fan of the war on drugs, but we do have a vested interest in seeing to it that those who partake do not become a danger to ourselves and others. It also stands to civil decency that we act within reason to prevent people from hurting themselves.
With a certain amount of taxation and regulation we might have something more workable. But in this life . . . there’s no hope of perfection.
