|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. It 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.
Most people snort small lines or "bumps" for a mild, dreamy effect. The effect comes on within about 5 to 10 minutes. 100mg is usually enough to enter a K-hole. If liquid is injected into the muscle, less is needed to enter a K-hole. Effects can be felt within four minutes. (Ketamine is never injected into the vein). If swallowed, the effects come on in 10 - 20 minutes. Some people become nauseous after taking ketamine.
Occasionally ketamine has been sold in a capsule as "Ecstasy," although it is nothing like MDMA (real ecstasy).
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.
