Rule, the whippets most of us use require effort to be inhaled, therefore, requiring one to be conscious in order to get more gas. So: If you pass out due to lack of oxygen, you are forced to breathe oxygen. What the wiki article is talking about is using a mask that stays on your mouth and requires no effort to inhale.
Not completely true. Many people have killed themselves with dust-off or asphyxiation through inhalants that require effort.
Dust-off != nitrous oxide. It contains fluorine and is completely irrelevant to the conversation we were having.
Additionally, if I can do drugs with only very minor harm done to my body, do them responisbly, and experience many things as a result, why does it become anyone's position to lead me against such actions?
Rule, as far as I could tell, this thread was a discussion regarding salvia, the methods of using it, and the experiences gained from it... Not whether or not to do it. Obviously, anyone posting saying that they want to do it wants to do it, and unless you have some form of actual statistic regarding health issues which it creates, or addiction, I don't see why there would be any need to lead someone against it. So far, it seems to me that your main argument is along the lines of "Why do you need to do it?" and my equally unlogical response of "shamanic/spiritual experiences" simply did not satisfy this. I was not trying to persuede you with some sort of "rationalisation," I was trying to explain the fact that most people who try it actually don't enjoy the experience, and, as a result, don't have much urge to repeat the trip.
To answer more thoroughly "Why do you do it?" (Which is a much more applicable question than "Why do you need to do it?"): It is an unclassifiable drug with features of both dissociatives and psychedelics, and therefor puts your mind in a state of temporary confusion, with much amnesia as well. It allows you to very shortly see things in a new light. After doing this, I am usually filled with a certain amount of a feeling of "Why am I doing this" whenever I do anything out of habit (Shaking someone's hand, waving at people, etc). It's a very interesting feeling/thought process, and it is very strange to act purely out of instinct, and note your actions.
