As ketamine is an anaesthetic, when used with depressant drugs such as alcohol, heroin or tranquillisers, it can be particularly harmful as it has the potential to shut the body down causing vital organs such as the lungs or heart to stop functioning.

Ketamine is considered a dissociative anaesthetic as it produces feelings of ‘disassociation’ from a person’s environment as well as from one’s self. It also has hallucinogenic effects and can impact on a person’s senses and perception of reality.
