Is ketamine safe?

No, not outside of medical care. Ketamine is used by doctors and vets, so a lot of people assume it must be safe. It is a real medicine. It is a licensed anaesthetic that blocks pain and makes a person feel cut off from their body and surroundings. That is why it is used in surgery and emergency care, and why vets use it to anaesthetise animals, including horses, cats and dogs. It also affects breathing less than many other anaesthetics, which is one reason it is used.

But in hospital it’s given in exact doses, by professionals, with equipment ready to support the patient’s breathing. Even then, ketamine can slow breathing, especially at higher doses or when it’s mixed with alcohol or other depressants. At a party or in someone’s bedroom there’s none of that. You can’t know the dose or exactly what’s in it, and nobody is watching your breathing.

Ketamine is an anaesthetic. It numbs pain and cuts you off from your body, and at higher doses you can lose control of your body.  That’s why it’s dangerous:

1. You may not feel pain properly,  so you can hurt yourself badly without noticing.

2. You can lose control of your body (a K-hole), leaving you unable to move, speak or get help.

3. It can make you vulnerable to being robbed, assaulted or taken advantage of.

4. Mixed with alcohol, benzos or other drugs, it can slow your breathing and heart to dangerous levels. People have died this way after mixing ketamine with other drugs.

5. There is no known safe amount for your bladder. Damage often starts with small signs, like needing to pee more or pain when you pee, and it can become permanent if you carry on.

6. Long-term heavy ketamine use has been linked to loss of grey matter, the part of the brain involved in thinking, emotion and decision-making.

Nobody can tell you a safe amount of street ket, because there isn’t a known one.
