The biggest anti-marijuana argument seems to be "it's illegal, so it should be illegal". Every scientific study has always shown that the harm from prohibition far exceeds any harm from use. Since newspapers are no longer major economic powers, the argument that hemp is a threat to the Hearst newsprint empire is no longer relevant, and protecting our children from exposure to dark-skinned people is no longer a major concern. And I see no harm in laborers being able to work long days with no ill effects. And, yes, quality has improved, but it is still physically impossible to consume a toxic level of marijuana. Hey, what were we talking about? Threat to the booze industry?
