Using a Whip cream canister to extract the nitrous oxide and inhaling.. Despite popular belief nitrous oxide is not significantly dangerous in less done without oxygen for long periods of time. Nitrous oxide is NOT an inhalant it is usually referred to as laughing gas and has shown no proof to be dangerous or to cause brain damage infact you may have tried it before it the dentist office. Short high kinda interesting worth a try i guess but I'd stick to weed ;)
Me and John might go whip-it since were out of weed.
