To the Editor: Recreational misuse of nitrous oxide remains a significant public health problem,1 sustained in part by the ready availability online of gas‐containing canisters intended for use in the catering industry. Known as “nangs” or “whippits” and usually purchased in bulk, each canister contains 8 g of nitrous oxide. When inhaled, this gives a seconds‐long “high”, which is typically prolonged by using several “nangs” in a single session. Some individuals can consume hundreds each day.
