What exactly is “laughing gas”?

"Laughing gas", whose chemical name is nitrous oxide, is a colorless, non-flammable, slightly sweet gas.

Laughing gas has been used as an anesthetic or analgesic for more than 200 years due to its pharmacological effects such as anesthesia and analgesia. It can also be used clinically for gynecological labor analgesia, anti-anxiety in dental care, improvement of withdrawal symptoms, and refractory depression.

In addition, because of its antibacterial, non-flammable and odorless properties, "laughing gas" is often used as a food additive. In the "National Food Safety Standard for the Use of Food Additives" (GB2760-2014) issued by the National Health and Family Planning Commission, nitrous oxide is listed in the "List of Processing Aids that Need to Specify Functions and Scopes of Use" and is approved as a propellant and foaming agent.

"Laughing gas" is safe to use under specified circumstances, but a very small number of people buy and sell it illegally. This is the main source of the abuse of "laughing gas". Users fill balloons with gas from a micro-compressor of nitrous oxide gas and inhale it in order to pursue physical euphoria and psychedelic effects.

Does “laughing gas” really make people laugh?

"Laughing gas" was first discovered in the late 18th century. Later, a British scientist Humphrey Davy found that inhaling "laughing gas" could make people feel highly excited and pleasurable, making them dance and laugh, so it was named "laughing gas". Its mechanism of action is mainly related to promoting the release of excitatory neurotransmitters such as dopamine in the body.
