At the beginning of April this year, the Public Security Bureau of Cixi City, Zhejiang Province found a large number of clues to illegally sell "laughing gas", which was mostly used by local young groups.

Police of Anti-drug Brigade of Public Security Bureau of Cixi City, Zhejiang Province: The people who took "laughing gas" were mainly born from 1995 to 2002. Most of them smoked "laughing gas" at first, mainly because they were curious. In addition, I was young at that time and didn't have a certain ability to distinguish. I just wanted to try some new things in society.

In society, some lawless elements package "laughing gas" into balloons and provide them to young people in entertainment places. It's called "Cheer up" in slang. This kind of balloon is called "Happy Balloon". According to the police, a small amount of "laughing gas" will have a slight anesthetic effect and produce hallucinations. A lot of laughing gas can cause headaches, incontinence, nerve damage, severe hypoxia and even suffocation on the spot.
