What is Ketamine?

Ketamine is also known as K, Ket, special K, Vitamin K, or horse tranquiliser.
 

Ketamine (ketamine hydrochloride) is a white powder, usually sold in ‘bumps’ or grams. A ‘bump’ is a small amount of powder which is snorted through a small glass inhaler called a bumper. Ketamine can also be swallowed, smoked, or injected.

Ketamine is commonly used by veterinarians to sedate animals such as horses. As with all drugs sold in powder form, ketamine may also be sold ‘cut’ (mixed) with other white powder substances which may or may not be harmful- people using this drug can never be 100% sure of what they’re getting. 

What are the effects of Ketamine?

If snorted or ‘bumped’, ketamine takes effect within 5-10 minutes (longer if swallowed). Its effects can last for a couple of hours.

The effects of ketamine vary, but may include:

  • Increased heart rate and body temperature
  • Drowsiness
  • Feeling of euphoria (a ‘high’)

  • Nausea and vomiting
  • Anxiety and panic attacks
  • Hallucinations (seeing or hearing things that aren’t really there)
  • Paranoia (feeling extremely suspicious and frightened)
  • Psychosis (see glossary)
  • An experience known as the ‘K-hole’ which is the feeling of being trapped in a state of detachment. This can be frightening
