I don't know how to tell people what drugs. You can't legalize marijuana they took LSD. Beware. Someone very powerful wants to destroy the world. Any drugs it's evil.
So penicillin is evil? Drugs are substances; a substance can't really be good or evil. Remember that all banned illegal drugs that have existed for more than a century, are usually former medicines. There is a reason why they know to inact legislation on the first place. I don't think all drugs have a place in mainstream society, but it's too broad to put all drugs in an evil place.
It's not true. Drugs have never been medicated. Previously, they were used as an anesthetic. Now, in some cases they are used for these purposes. This is not to say that you want to allow free access to them.
