How do you pay?
Your question was not addressed to me, but I will hazard the guess that we pay through all the social programs that support people who abuse themselves in any way - drugs, diet, stupid hikers who get lost and require search and rescue, etc.
My two-pronged approach to mitigating (not solving) our drug problem:
1) Legalize soft drugs, and regulate hard drugs with appropriate restrictions.
2) End the nanny/welfare state, so we don't have to pay for other people's bad choices.
Got to run errands now. I will be back in a couple of hours to see if this thread still has any legs.
How do I pay what?
