Ketamine can cause perceptual changes or hallucinations like LSD, in addition to its effects on reducing bodily sensation. Users can trip for up to an hour and may feel after-effects for some hours.   It can give the user a floating feeling as if the mind and body have been separated.


Legally produced ketamine comes in liquid form which is usually injected. The illegally produced version usually comes as a grainy white powder which is usually snorted but it may also be obtained as a tablet.

HEALTH RISKS (long term) which includes withdrawal & tolerance:

Users may be physically incapable of moving while under the influence.  Ketamine can cause panic attacks, depression, and taken in large doses, can make existing mental health problems worse.  Because you don't feel any pain when you're on ketamine, you can injure yourself badly and not know you've done it.  High doses, especially with other depressant drugs like alcohol, can dangerously suppress breathing and heart function and can lead to unconsciousness.  Ketamine is very dangerous when mixed with ecstasy or amphetamines. It can result in high blood pressure. If high enough doses are taken, the anesthetic effect can result in death, for example due to unconsciousness and inhalation of vomit.  There are few known cases of death from Ketamine use in the UK.


Ketamine is a prescription only medicine.  Possession of ketamine without a prescription is not illegal.  Supply (selling or giving it to another person) is against the law and Class C penalties may apply.   The maximum penalty for supply of a Class C drug is 5 years prison and/or a fine.

  1. Ketamine is a drug used in human and veterinary medicine developed by 1962.
  2. The drug was first given to American soldiers during the Vietnam War.
  3. It is primarily used for the induction and maintenance of general anaesthetic usually in combination with some sedative drug.
  4. Ketamine tends to increase heart rate and blood pressure.
  5. Ketamine sold illicitly comes from diverted legitimate supplies and semi-legitimate suppliers, or theft, primarily from veterinary clinics.
  6. Most of the world's illicit ketamine comes from Asia-based pharmaceutical manufacturers, who often willingly sell it to Western individuals, who then sell it to users.
  7. Many ounces or even kilos of pharmaceutical ketamine are sold and shipped in each transaction by legitimate Asian producers, who will sometimes relabel the packaging before shipping with names of unregulated chemicals, making it harder for customs to discover the shipments
  8. At low doses, hallucinations are only seen when one is in a dark room with one's eyes closed, while at medium to high doses the effects are far more intense and obvious
  9. Long term use may result in damage to the liver or urinary bladder, or even acute renal failure.
  10. Ketamine is stronger than the same amount of speed or coke and the more you take the stronger the effects.
