Depends on the drug. I think only soft drugs should be legal, such as marijuana. Something bad as an example would be crystal meth. It isn't something where people say "it's poison for the human mind." Crystal meth actually is poison that is incredibly harmful. In a recent Vancouver study, they anonymously asked drug users to bring in their drugs to be tested. About eighty percent of the hard drugs weren't the actual drug, or had been diluted with other products, most of which were harmful. You can't get a reliable product, and when you do, it is possibly deadly due to body chemistry.
