How does it make you feel?

Ketamine is a general anaesthetic so it reduces sensations in the body. Trips can last for a couple of hours.

Taking ketamine can make you feel:

  • dream-like and detached
  • chilled, relaxed and happy
  • confused and nauseated

Ketamine can also:

  • alter your perception of time and space and make you hallucinate (see or hear things that aren't there)
  • stop you feeling pain, putting you at risk of hurting yourself and not realising it

If you take too much ketamine you may lose the ability to move and go into a ‘k-hole’. This feels like your mind and body have separated and you can't to do anything about it – which can be a very scary experience.

Regular ketamine use can cause:

  • agitation
  • panic attacks
  • damage to short- and long-term memory
  • depression, if taken frequently

How does it make people behave?

It can make people seem slower, more relaxed and chilled out, but it can also stop people from being able to move properly and from making sense.
