That's insane.
Look at the amount of death and destruction alcohol causes in our society, and you want to legalize meth, crack, cocaine, heroine, and pot? Do you really want to live in a hell on Earth? Do you really want to condemn tens of millions of people to the life of an addict?
Why not give police officers the power to shoot dead on sight anyone they pull over who's got drugs in their car. Go after the drug lords with Navy Seals, and hang drug dealers from the corner street light where they sell their poison from. It would result in far fewer deaths and a lot less misery than your way.
