This is a topic that I can appreciate both sides of the argument. On one side, there is personal responsibility, and the liberty to make your own choices, even if they're bad choices. On the other hand, we do have responsibility to look out for the least among us, those who would make those bad choices. I think the thing that tips the scale for me, in favor of making dangerous drugs illegal, is that it takes a strong society, with a strong moral fiber, that would produce citizens capable of making those kinds of choices.
America is no longer a country with that strong moral fiber.
