The decision was made following a proposal by the People’s Committee of Hanoi to ban selling the gas for recreational purposes due to adverse effects that could lead to death.
The gas is being used widely among youth in the form of funky balloons or nitrous oxide-filled balloons, despite warnings from experts who say the balls can be addictive and negatively affect the nervous system of users.
Nitrous oxide is also known as laughing gas, and after inhaling it, people burst into laughter.
Dr Nguyen Anh Vu, from the Hanoi University of Science and Technology’s School of Chemical Engineering, said that nitrous oxide creates an instantly refreshing feeling but also leads to dizziness. It blocks the nervous system, reducing the ability to think, distorting sounds, and even causing visual hallucinations.
A person exposed to nitrous oxide in a closed room or inhaling it directly will suffer from a lack of oxygen in their bloodstream, he said.
According to scientists, young women have been advised to avoid exposure to nitrous oxide because it might lead to fertility problems.
In a document sent to the Hanoi People’s Committee on May 29, the Ministry of Health said according to a regulation set by the Ministry of Industry and Trade which manages the use of nitrous oxide, the gas is only permitted to be sold and used for industrial production, not for human use.
The ministry instructed the Hanoi People’s Committee to continue to disseminate information to raise public awareness about the adverse effects of the use of the nitrous oxide.
