Ketamine: Ketamine is a fast acting anesthetic and can be used on both humans and animals. As a drug of abuse it can be taken orally, snorted, or injected, and can be sprinkled on marijuana or tobacco and smoked. If used intravenously, effects can be felt immediately and if snorted or taken orally, effects are evident in 10-15 minutes.
Ketamine can act as a depressant or a psychedelic and low doses can produce vertigo, slurred speech, slow reaction time and euphoria. In higher doses, Ketamine produces amnesia and coma.
