University of Otago researchers are calling for participants in a trial, looking into how a popular recreational drug could help treat depression.
Ketamine has grown in reputation as an illicit drug of choice for many, who use it for its anaesthetic and psychedelic properties.
Dr Ben Beaglehole is looking for 60 people to help investigate if the drug can help those with "treatment-resistant depression."
Beaglehole spoke to Corin Dann.
