Its correct - Nitrous Oxide known as the "Laughing Gas" which was synthesized by Joseph Priestly and Humphrey Davy in 1776. It became popular that people would even pay to experience its effects.

In 1776 Joseph Priestley discovered that nitrous oxide has anesthetic properties and could be used for painless surgery in place of ether or chloroform.
