One of the first NHS clinics dedicated to helping 'club drug' addicts has been opened. Doctors have opened the centre in London because they claim there is a 'higher demand' from people who use drugs such as ketamine, ecstasy and 'legal highs'. At present, existing clinics cater for those addicted to alcohol, heroin and crack cocaine, which means they are unable to deal with the specific needs of 'club drug' users.
