I'm starting to find that conservatives are becoming stronger proponents of welfare that I used to think they were. They need it because welfare is their last excuse for justifying prohibition. "We can't legalize drugs because the drug users will just go on welfare!" Take that away and it just makes them look like a bunch of busybodies who want to meddle in the lives of others with stollen money.
I have never heard of an argument that linked drugs and welfare.
First, drug users now get welfare.
Second, legal drugs should have the price go down since most costs are associated with reacting to law enforcement.
Third, legal drugs should kill many illegal drug users, decreasing welfare costs.
