Officials from Thailand’s Food and Drug Administration (FDA) and police from the Children’s and Women’s Welfare Division raided 14 tourist spots in Bangkok on Friday night and seized large quantities of nitrous oxide, commonly known as ‘laughing gas’.

FDA secretary-general Dr. Tharet Kratsanairaviwong said that nitrous oxide can be life-threatening if inhaled for a long period of time, noting that the gas is commonly used to sedate patients undergoing a minor operation or used as pain relief by dentists.

It was discovered that the gas was being sold illegally at several night entertainment areas frequented by tourists. Inhaling nitrous oxide produces rapid onset of euphoria and a feeling of floating or excitement for a short period of time. Continued inhalation may cause dizziness, vomiting and disorientation which may, in turn, result in severe injury or death.

Meanwhile, FDS deputy secretary-general Supatra Boonserm said vendors of the nitrous oxide face a maximum jail term of five years and a fine of 10,000 baht if they do not have the appropriate permits.
