In phase 2 clinical trials, researchers found nitrous oxide improved depression for over two weeks

See, laughter is the best medicine, even, if it's chemically induced. Ha, ha!
This makes me think of one of the most loathsome fictional characters, ever, Frank Booth, played by Dennis Hopper, int the 1986 film, Blue Velvet. Frank Booth inhaled gas from a canister. The script specified helium to raise his voice but I always thought it was nitrous oxide. I read that some people abuse it from cartridges used to make whipped cream.
Warning to depressed people:

Abstract
Nitrous oxide is increasingly being used as a recreational drug. Prolonged use of nitrous oxide can have disabling neurological sequelae due to functional inactivation of vitamin B12. We present three cases illustrating the neurological complications of using nitrous oxide. Two of these patients received nitrous oxide as a consequence of repeated hospital attendance and the third via ‘Whippit’ canisters used in cream dispensers, which are now widely available. Two patients developed sensorimotor peripheral neuropathy with demyelinating features with no clinical or imaging evidence of myelopathy, emphasising that not all patients develop subacute combined degeneration of the spinal cord (the typical presentation of functional vitamin B12 deficiency). The diagnosis was based upon the history of nitrous oxide use and raised levels of homocysteine and/or methylmalonic acid. All patients were treated with parenteral vitamin B12 with partial recovery, though two were left significantly disabled.
