  • 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.




  • 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.




  • While low doses of Ketamine can increase heart-rate, at higher doses it depresses consciousness and breathing and is extremely dangerous to combine with downers like alcohol, Valium or GHB.

  • Frequent use can cause disruptions in consciousness and lead to neuroses or other mental disorders.

  • Ketamine can cause a tremendous psychological dependence. The dissociation from one's consciousness experienced with ketamine can be highly seductive to some people, and there are many cases of ketamine addiction.

  • Ketamine is illegal and possession can result in long prison terms.
