Health Canada has issued a recall for “laughing gas” that it says is being sold without authorization and presents a serious safety risk.
Nitrous oxide, also known as laughing gas, is legal in Canada when it is administered by a health care professional, such as for dental surgery or medical procedures for sedation or pain relief. The gas is also found in cream dispensers and some food tools but is not mean to be inhaled, Health Canada said.
