The effects of Ketamine

There has been an increase in Ketamine use in New Zealand over recent times. Here’s what you need to know…

KnowYourStuffNZ has seen a notable increase across the 2019/20 festival season, and trends suggest this will continue to increase. 

Ketamine is a sedative drug, or dissociative anaesthetic, developed in the 1960s for medical use. It is also known as Ket, K, Special K, VitaminK, or Wonk. It is typically bought as a fine white powder which is usually snorted.

People who take ketamine can experience a sense of detachment from their body and surroundings.

The major effects include:

  • Feeling bouncy
  • Dizziness
  • Delusions
  • Visual hallucinations
  • Vomiting (especially when taken with alcohol)

Higher doses can lead to a ‘K Hole’. This is when someone seems unresponsive, while at the same time experiencing vivid hallucinations.

Effects usually start within 7-20 minutes, peaking between 30-60 minutes, and the after effects can last from 2-12 hours. Ketamine stays in the system after the effects stop, so taking more can lead to stronger effects than expected.

Ketamine is a powerful anesthetic that can cause serious harm. Some of the risks include accidents while intoxicated, dependence, nasal damage, disturbing hallucinations, psychosis, and bladder problems. It can be fatal, particularly if mixed with other drugs.

While no drug use is safe, there are some steps that can help reduce the risks.

  • Low doses are safer. The K Hole can be a very disturbing experience, especially if it wasn’t the intended effect.
  • When it comes to repeated dosing, Ketamine has a cumulative effect and it is easy to push it too far.
  • As always, avoid mixing drugs as the combined effects can be unpredictable and increase risk. Especially avoid mixing ketamine with depressants like alcohol, benzos and opiates, as the combined sedative effect increases the risk of choking, overdose or losing consciousness.
  • Regular users experience bladder problems – including UTI’s, cystitis, and a risk of ulcerated bladder. Seek medical advice and do not take ketamine to reduce the painful symptoms.
  • Try to use in a safe and calm environment. As with all drugs, it’s better to have people around that you trust and who have knowledge of first aid.

What to do in an emergency

If you think someone is suffering from an overdose:

  • Call 111 immediately and ask for an ambulance.
  • Don’t panic. Stay calm.
  • Keep yourself safe. Watch out for used needles and blood on the bed or floor etc.
  • Check if the person is conscious by gently shaking them and calling their name or asking if they’re ok. This may bring the person round.
  • If the person does not respond, check whether they are breathing.
  • Check their airway. Tilt their head back enough to open their airway. Remove anything from their mouth like food or vomit.
  • Are they breathing? Put you ear next to their mouth. Can you feel any breath? Is their chest rising?
  • If they are breathing put them in the recovery position.
  • If they are not breathing start CPR.
