Nitrous oxide acts as a mild inhalation anesthetic

Laughing gas alters neurochemical signaling to relieve pain and induce euphoria

Nitrous oxide is a colourless inorganic gas with a slightly sweet odour and taste. When inhaled, it dissolves quickly into the bloodstream and crosses the blood-brain barrier to modulate NMDA receptors and endorphin release. This neurochemical interaction provides fast-acting analgesia and mild euphoria, making it useful in dental surgery.
