WHAT IS KETAMINE?
Ketamine hydrochloride ("Special K" or "K") was originally created for use as a human anaesthetic, and is still used as a general anaesthetic for children, persons of poor health, and in veterinary medicine.
Ketamine belongs to a class of drugs called "dissociative anaesthetics," which separate perception from sensation. Other drugs in this category include PCP, DXM and nitrous oxide (laughing gas).
Ketamine usually comes as a liquid in small pharmaceutical bottles, and is most often cooked into a white powder for snorting.
WHAT ARE THE EFFECTS?
At lower doses it has a mild, dreamy feeling similar to nitrous oxide. Users report feeling floaty and slightly outside their body. Numbness in the extremities is also common.
Higher doses produce a hallucinogenic (trippy) effect, and may cause the user to feel very far away from their body.
This experience is often referred to as entering a "K-hole" and has been compared to a near death experience with sensations of rising above one's body. Many users find the experience spiritually significant , while others find it frightening.
While in a K-hole it is very difficult to move. People usually remain seated or lying down during the experience.
