(1) i assume he just took one or two good puffs of it, not a 1+ hour smoking session. inhaling a small volume of CO2 won't hurt you (...probably), but doing it continuously == suffocation. brains need their oxygen.
(2) the other thing you mentioned is probably not welcome on this forum. though there are legitimate medical uses for 'laughing gas,' no medical professional would use that term. also, the gas used there is N2O (nitrous oxide), not CO2 (carbon dioxide).
