No problem Sesame, I'd LOVE to, that said, I could probably write a book on the topic of drugs and my own personal history. So if you could simplify your inquiry a bit, I'd be more than willing to accomadate. I guess in saying that, is there any place you'd like to start the discussion/comparison? To simply ask me to describe them all is a bit overwhelming...I don't mind doing it, but a bit of direction regarding what to cover first would be appreciated. :O It's refreshing to see someone who appreciates a girl with a bit of knowledge regarding altered states.
