Ketamine is used by medical practitioners and veterinarians as an anaesthetic. It is sometimes used illegally by people to get high.
Ketamine can produce psychedelic effects, causing a person to see, hear, smell, feel or taste things that aren’t really there or are different from how they are in reality.
When it’s sold illegally, ketamine usually comes as a white crystalline powder. It can also be made into tablets and pills, or dissolved in a liquid.1
A number of clinical trials and studies are currently being undertaken to assess ketamine as a treatment for depression, early indications are showing good results.
