"Do what thou wilt shall be the whole of the law"
Well, not quite... but what how people wish to live their lives should be up to them and up for negotiation with those it affects directly. Also, what kinda drugs are we talking?
--- I've been an experience seeker at points my life and have drawn my conclusions from first hand experience and observations ---
I might not like alcohol or tabacco, but I don't think it's my place to legally punish those who do, or to criminalize the behavior.
Having been to a few grass bars or 'hash cafes' over the span of my life, I have a hard time envisioning fights breaking out there. Even if you're not smoking or vaporizing, the staff and clientele all grin and move in a languid, fluid slow motion. Doesn't speak harm to me.
I think entheogens or hallucinogens get a bad rap, too. They're been consistently positive, if bewildering, spiritually affirmative experiences for me. I'm not normally given to much spirtual pondering, but it's helped me see why many people ARE.
As for other stuff, coke, smack, designer chemicals, etc, they can be *very* fun, but very shallow, transient experiences... they tend to attract a bad crowd and bad behavior. Regardless, harm reduction seems preferable to legalization. People do what they do and unfortunately I've seen some friends turn into junkies... That said, my observations seem to note that most people who go the farthest in abusing powerful stimulants and depressants are those with previously existing and co morbid mental disorders.
Finally, there are the no-benefits killer drugs that really *should* be banned and enforced, since they are either too personally toxic to tolerate or prone to being used to hurt people. Rust/Oxi, Krokodil, Scropolamine, Bath Salts/MDVP, fentanyl (anywhere but under doc supervision) and arguably more common fare like crystal methamphetamine or PCP. Just bad news with almost nothing to offer but delirium and pain.
