I agree.
But you can't unleash legal drugs on a nanny state like ours without expecting to increase costs to the taxpayer. As Ann Coulter states in an excellent piece, "It's not as if we live in the perfect Libertarian state of nature, with the tiny exception of those pesky drug laws."
This country of ours has a ways to go in the areas of personal responsibility, tort reform, and the dismantling of our socialist-leaning government before I'm comfortable with supporting a relaxation of our current drug laws.
