Ketamine is a strong medication used for pain relief and sleepiness, but it is also used illegally as a drug. It is usually found as a white powder or liquid, and can be injected, snorted, or eaten. Ketamine works by blocking signals in the brain's neurotransmitter system which helps with pain relief and calming effects. When used as a drug, ketamine can cause hallucinations, feeling disconnected from reality, and a sense of being separate from one's body and surroundings. It is classified as a powerful painkiller and has a high risk of misuse and addiction. Misusing ketamine can lead to serious health problems, including breathing issues, confusion, and even death.
