I'd prefer redirecting the money we now futilely spend on apprehension and incarceration - but I'd like best of all leaving that money in the pockets of those who earned it.
Well if we could wipe out all the drug pushers, then we could keep our own money, but it is those people who are constantly pushing drugs on us that are costing the money.
Till we get rid of them, we are going to have to keep paying the money to prevent them from hurting people by exposing them to drugs.
