Nitrous oxide (N2O), discovered in the 1700s and used as an anesthetic since the 1840s, has shown promise as a rapid antidepressant through NMDA receptor blockade and mu-opioid receptor activation, with effects lasting about a day and wearing off within a week; however, recreational use poses serious risks including vitamin B12 deficiency causing permanent neural damage and oxygen deprivation leading to death, with over 150 Americans dying annually from N2O abuse, raising concerns that restrictions on recreational use may hinder legitimate medical applications.
