Yes. I haven't tried every pharmaceutical but I've tried most illicit drugs. Off the top of my head one of the few I haven't tried is PCP for the dual reasons that the reported effects kind of scare me (I'm not too keen on experiencing a full-blown psychotic episode thanks) and also because I've never heard of it being available in Western Australia.
