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 Id stick to weed 😉
