Ketamine is a depressant drug which has severe sedative effects and was originally designed as a medication used for anaesthesia.

As a depressant drug, ketamine slows down the body’s functions. It produces a trance-like state and stops the brain from interpreting pain and causes memory loss. This state is sometimes referred to as a ‘k-hole’.

Ketamine comes in a clear liquid or crystal-like powder. It is often made into tablets.

Due to its anaesthetic effects,  ketamine has also been used for drink spiking.

Other nicknames for ketamine include: special k, k, tranquilliser, kit kat, super k, horse trank, lady k, vitamin k, ket.

Drug use can have a range of social consequences and can have impact not only on an individual, but also their relationships and their work or study. Drug use can cause financial issues, family problems and can also have legal consequences.

If you are concerned about your own or another person’s drug use we encourage you to seek professional help and assistance.

There are always risks associated with drug use. No use at all is the safest option.

If you suspect someone’s drink has been spiked, stay with them and seek urgent medical attention. If the person is unconscious or seriously unwell, call triple zero (000) immediately.

To report a drink spiking incident, which is not an emergency, call NSW Police on  131 444 or visit your local police station.
