Wow, that really does sound like a much more potent nitrous oxide trip. Back in my less responsible days I definitely dabbled in "hippie crack", and you could sort of hit that state if you took enough and / or combined it with other drugs.

(fwiw, I don't take any drugs anymore, except for the occasional night drinking. I had some horrifically bad trips that felt like my consciousness was smeared across the entire universe, suffering for eternity. Took me a long time to recover, and the message I took away was "anything you can learn on drugs you can learn in other, safer ways".)

If it gets them to the top of Everest, it would probably be the 5.5 mile high club.
