Nangs are small canisters of nitrous oxide (N2O), also known as laughing gas. They are often used recreationally for a brief euphoric "high" by inhaling the gas released from the canisters, typically via balloons. Medically, nitrous oxide is used as an anesthetic and pain relief agent during procedures like childbirth and dental work. Recreationally, the term "nangs" comes from the distorted, repetitive sound made when the gas is inhaled. While commonly used at parties or music festivals, nitrous oxide inhalation carries health risks such as memory loss, vitamin B12 depletion, nerve damage, and potential psychological effects. It is inexpensive and widely available in small canisters often intended as whipped cream propellants.
