There is some serious misunderstanding going on there.
I can agree that would an incredible thing to partake in but I have this weird thing about having oxygen around when I breathe...it just seems so normal you know.
I highly doubt {pun intended} the amount of oxygen left in that room was sufficient, it's good thing none of them has serious {lung} health issues.
It's not something everyone can do I'm afraid and this video kind of promotes this type of smoking...I guess I'm concerned that someone who isn't healthy enough will try something like this and have a really bad reaction or worse die, leaving the media to blow it all out of proportion.
Kick ass vid though
