The place of drugs in the good society is not about the drugs as such, but rather the freedom and the value to individuals and their society of openness to experimentation and alternative behaviours and lifestyles. The good society is permissive, seeking to protect third parties from harm but not presuming to order people to take this or that view about what is in their own good.This seems to document the link between libertarians and buggery.
I was under the assumption that everybody already knew that.
