@d0zer, you obviously haven't even read the research that's out there, even when it's presented in a reader's digest format with links embedded. You refuse to learn; you plug your ears and close your eyes and parrot modern reefer madness rhetroric without doing any research yourself. Your remarks are cliches used by people who want to minimize research and stop progress...the point where we have enough research will be just forever out of grasp.
