As a fellow libertarian I agree that drugs should be completely legalized and regulated by the market. As a registered nurse and marijuana advocate I have to ask how is marijuana bad for you? There is some evidence that it's not good for adolescent minds and people who are genetically predisposed to schizophrenia, however I don't know of any medication that doesn't have side effects in some populations. There have even been studies that it is good for asthma, emphysema, and prevents lung cancer.
