Waste anesthetic gases include enflurane, fluroxene, halothane, methoxyflurane, and nitrous oxide. There is limited positive data and limited negative data that anesthetic gases cause reduced fertility and spontaneous abortions in humans and birth defects in animals.

PMID 27542098] Enflurane, halothane, and nitrous oxide are in the list of "Some volatile substances which may be abused by inhalation" published on the web site of the U.N. International Drug Control Programme, indicating a potential to cause narcosis in workers.
