Yes, nitrous oxide (or laughing gas) is nitrous oxide. Nitrous oxide, also known as laughing gas, is a colorless gas with a sweet taste and is an oxidizing agent. It was once used as an anesthetic in hospitals. Inhaling large amounts can cause a range of side effects, including hallucinations, confusion, delirium, intellectual and visual impairments, and reduced muscle contraction.

According to the UK Medicines Act, canned nitrous oxide used for medical anesthesia cannot be used for recreational purposes. Anyone selling nitrous oxide-containing drugs for inhalation without a permit or supplying them without a prescription can be sentenced to up to two years imprisonment and an unlimited fine.
