It is an anaesthetic with stimulant and psychedelic properties. Legally produced ketamine comes in liquid form which is injected. The illegally produced version usually comes as a grainy white powder which is snorted or bought as a tablet. Some tablets have motifs and logos making it difficult to distinguish from ecstasy.

At higher doses (200mg and over) the user will often experience hallucinations, similar to LSD and a typical out-of-of-body or detached experience. This is often followed by numbness, often in the limbs, and strange muscle movements. Users may also feel sick or throw up.

Paraphernalia / what to look out for

  • Powder, tablets, small phials of liquid.

Possible short-term indicators

  • Users may feel euphoria, depersonalisation, confusion, stimulation and hallucinations.
  • Physical sensations may include nausea, vomiting, slurring of speech, lack of co-ordination and numbness.

Possible longer-term indicators

  • There is little evidence in relation to the long-term effects of ketamine use.
  • Tolerance can develop quickly, but not physical dependence.
  • Some people may develop psychological dependence.
