> Should any substance which enhances the risk of schizophrenia be legalized? Yes, of course. Substances that enhance the risk of death are legalised, after all. :) I think what you may mean is "does this specific substance present unacceptably high risks relative to the benefits?" And the answer from your link seems to be "no". Any attempt to make policy while only looking at the costs (or benefits) in isolation is doomed to failure.
