The law:

Ketamine is an anaesthetic with hallucinogenic properties. It is often abused because of its hallucinogenic effects/

Users may report hallucinations or ‘out of body’ experiences for up to three hours, during which time they may be physically unable to move
as with LSD, the nature of the hallucinations is unpredictable.

Ketamine numbs the body, so users risk serious injury without feeling pain. Excessive doses carry a risk of breathing problems and heart failure. The effects of the drug can be very alarming if the user isn’t expecting them. Mixing ketamine with other drugs and alcohol is very dangerous.
