I read the posts on this subject without much attention; it wasn't something I was likely to use. Then I realized that this Nitrous Oxide was the "Laughing gas" of another generation. It's used as a propellant in some whipped cream, making these products a source of abuse for teens to get "high." Used in dentistry for eons it has generally been considered safe. In medicine it's usually combined with 20 to 50% oxygen as a safety feature. Is anything ever safe? Some years ago a friend of mine had a teen-age son who was rather industrious. He worked at night cleaning offices. One of those offices belonged to a dentist. The young man tried experimenting with the gas. He was found dead in the morning. Just the facts.
