Nitrous oxide is not a laughing matter

Medical professionals are calling for tighter restrictions on the sale of nitrous oxide gas cartridges, colloquially known as “nangs,” due to potentially serious harm for users including lasting neurological damage. Nitrous oxide or “laughing gas” is normally used by dentists and medical professionals to provide sedation and pain relief to patients undergoing minor procedures. It’s also a food additive, used to aerate whipped cream, and sold in gas cartridges online and in convenience stores.
