> Frankly, I have never understood the desire to make a plant illegal. If you're a religious person this is something God made. Who are we to question God's creation?
This is kind of a silly argument, though. Malaria, anthrax, and the black death are also natural, and you won't find many theists arguing that we should welcome those.
(I am absolutely in favor of legalization, I just don't like silly arguments.)
