Ketamine is used by medical practitioners and veterinarians as an anaesthetic. It’s sometimes used illegally by people to get high.
Ketamine is a dissociative drug, which means it acts on different chemicals in the brain to produce visual and auditory distortion, and a detachment from reality.
When it’s sold illegally, ketamine usually comes as a white or off-white powder. It can also be made into pills, or dissolved in a liquid.1
Clinical trials and studies are assessing ketamine as a treatment for depression. Early indications show good results.2
