You see more and more the silver tubes of laughing gas on the street. Laughing gas has been legally for sale since July, because it falls under the Commodities Act and that has consequences.
Laughing gas is used by hospitals, for example, to make a hospital visit less exciting for children. It is less pleasant that more and more young people are using laughing gas as a drug.
The Ministry of Health, Welfare and Sport will investigate the use of nitrous oxide, who uses it, in what quantities, and what are the risks? More should be known about this in 2017.
