Ketamine is becoming much more popular in the Kiwi party scene.

The New Zealand Drug Trends Survey shows 73 percent of respondents have no trouble getting their hands on the dissociative anaesthetic.

The inflation adjusted price of MDMA has tumbled 47 percent since 2017.

Drug testing agency KnowYourStuff general manager, Casey Spearin, says use of ketamine's climbed since 2018.

"We hear, anecdotally, of students not drinking as much, people not drinking as much - and ketamine is certainly a way to have similar effects without the price and the hangovers the next day."
