The history is largely unknown, but its following of cultish proportions has become a topic of interest on its own. Nitrous oxide is a gas used to make whipped cream, and can be purchased in packages of several cartridges. Though illegal to use as an inhalant, nitrous oxide (often called “whippits”) is utilized by many young people, especially adolescents with limited incomes, to achieve a cheap and quick high. A balloon is inflated with a nitrous cartridge, and is fastened to the slide of an already-lit bong. The hit is inhaled as the balloon is released, allowing the individual to experience a bong rip and a nitrous hit simultaneously.
