Harmfulness of laughing gas is no different from drug abuse
Laughing gas, scientific name nitrous oxide, is a colorless and sweet gas. Since being discovered by British scientists for anesthesia in 1799, he has embarked on a stage of history. Until recently, after the development of more advanced anesthesia techniques, the role of laughing gas in the medical field gradually weakened. In daily life, laughter is widely known for making cake decorating, fancy coffee, and molecular delicacies. The cream guns we see in cake shops and cafes rely on "smile" to make the cream thick foam. If it is used in food, it is not harmful to the human body. If it is used for smoking, it will cause harm to the body!
In China, laughter can also be traced online and in some entertainment venues. Although it is not included in the list, it does not mean that it is not harmful. Lu Lin, an expert at the China Institute for Drug Dependence, who has been conducting drug dependence and neuropharmaceutical research for a long time, said, "Nitrous oxide is undoubtedly toxic, why make you laugh? It stimulates your nerves, a small amount It may not be obvious, but if the dose is large, it may be obvious, causing dose toxicity. After a long time, it will be dizzy, memory loss, and work efficiency. If there are no side effects in a short period of time, it will cause cognitive impairment and memory impairment. , Or even damage brain function. "
