Could laughing gas be used to treat depression?
Study reveals low doses of nitrous oxide can relieve symptoms for up to two weeks. Experts led from the University of Chicago ran trials involving 24 patients. Each was given an hour's session inhaling 25 or 50% laughing gas or a placebo. The team found that the 25% gas mixture was nearly as effective as the 50% one. Furthermore, it cut down on negative side effects like nausea by three-quarters. Laughing gas could be used on patients with treatment-resistant depression.
