The discovery of nitrous oxide was in the year 1772 by an English scientist named Joseph Priestly. It was first used by a dentist named Dr. Horace wells as an anesthetic for dental procedures. 2 It is gas drug and is taken by inhaling froma mask in a dentist’s office, or fromsomething like a balloon or a canister when it is abused. 1

There are a fair amount of different interactions nitrous oxide has with other medications. Of note, any drugs that may also cause CNS depressant effects such as alcohol, opioids, and other medications like Ambien. Therefore, it is very important to avoid taking this medication while on any other depressants, because of the enhanced depressive effect.3

When this drug is being used, it is important to watch for any rebound hypertension that can result.3 Also, it is not on routine drug screening panels, but can be detected in the urine.5

My professional opinion about the use of nitrous oxide is that it is applicable for dental procedures, but should not be prescribed for any other reason than anesthesia to help prevent supply from reaching the general public.
