Nitrous oxide deaths spur push for tighter restrictions on recreational sales

A growing number of deaths and serious injuries linked to recreational nitrous oxide use are fueling a push for tighter restrictions on a gas commonly sold at smoke shops, gas stations, and online, with advocates urging Congress to limit consumer access.

The substance, commonly known as laughing gas, is used medically for anesthesia and pain relief and commercially to make whipped cream. But products containing the gas marketed under names such as Galaxy Gas, Goo Sticks, and Whip-its have also become popular among recreational users, raising concerns about the risks of inhaling the gas and the ease with which young people can obtain the substance in many states.
