Nitrous oxide (N2O)

 Nitrous oxide (commonly known as laughing gas) is legally used in medical treatments, food production, and industrial processes. However, in recent years, some unscrupulous individuals have been illegally selling nitrous oxide to the general public for recreational inhalation, leading to serious physical and psychological harm.

In response, the Executive Yuan has designated nitrous oxide as a chemical of concern. Anyone who handles it without approval, fails to report as required, or does not comply with labeling regulations may be fined between NT$30,000 and NT$300,000 in accordance with Article 61 of the Toxic and Concerned Chemical Substances Control Act.

SGS, as a laboratory certified by the Ministry of Environment to conduct nitrous oxide analysis, can assist law enforcement agencies and relevant organizations in carrying out testing.
