Ketamine is a narcotic that has a dream-like effect. It separates body and mind. The drug is sold as a white powder or in liquid or pill form. A low dose gives a euphoric and trippy feeling. Higher doses intensify the trippy effect, with the extreme being what is known as a “K-hole”. In this surreal state, you feel disconnected from your own body. A K-hole is often experienced as very unpleasant and frightening.

Tips for use

  • Have your ketamine tested freely and anonymously at a testing service near you.
  • Ketamine can cause a bad trip and exacerbate existing mental health problems.
  • It is important to dose ketamine accurately. You need much less to get the desired effect than other snortable powders.
  • Beware of using ketamine in public places. You may become disoriented and have difficulty moving, causing you to stumble or fall.
  • When using ketamine for the first time, do it at home, start with a low dose and make sure someone with ketamine experience is around.
  • Ketamine reduces muscle control. It is best to use it sitting or lying down.
  • An adverse side effect of ketamine is nausea. Use on an empty stomach.
  •  If you experience adverse effects, remember that the drug will wear off within one hour. This can feel like a very long time because time seems to move very slowly when using.
  • Stop using ketamine if you develop bladder problems.
  • Never combine ketamine with other downers, such as alcohol or GHB/GBL. This increases the likelihood of passing out.
  • If you snort ketamine, clean your nose before going to bed. Use a moist cotton bud, a nasal douche, or spray to remove the residue in your nose, or clean your nose with your fingers while showering.
  • Expect an intense experience when slamming ketamine intramuscularly (into muscle tissue). Make sure you can lie down and use only sterile material. Note: Slamming is more likely to result in dependence on ketamine than other methods, such as snorting.
  • Do not participate in traffic. Ketamine affects your ability to react.
  • Do not use during pregnancy. Ketamine is harmful to your unborn child.
