Maybe, but I would argue that it's the conservative view. Another poster referenced the 10th Amendment. We seem to have drifted away from it by quite a stretch. I don't smoke the stuff, and have no interest to, but it's time to walk away from this nonsense.
How is using a certain herb or medicine a federal issue? Conservative to me means conservatively following the constitution. I want freedom for all, whenever possible. People dont have to please me with their lifestyle.
