Ketamine - which is often used as a tranquiliser for horses - is the fastest growing drug in the U.K. It is used on the dance scene and can produce effects of sedation, hallucinations and dissociation. Researchers at University College London studied 30 long-term users of the drug and found that it can have severe side effects. The study found that ketamine had a 'profound' impact on short and long-term memory, leading users to become 'dissociated' in their everyday lives and leaving them struggling to remember names and conversations. The drug also made people completely unresponsive to events around them making them more vulnerable to accidents. Ketamine was also linked to symptoms of depression and in the past it has been linked to breathing and bladder problems.
