confidential GP service for health professionals has warned.
In its first year the clinic has treated NHS staff hooked on drugs including heroin, ketamine, a horse tranquillizer, and methadone, a drug linked to amphetamines, said Dr Clare Gerada, medical director of the Practitioner Health Programme.
The service also uncovered six cases of undiagnosed psychosis, in which sufferers see things or hear voices.
The clinic was set up amid fears many health professionals were treating themselves or avoiding their local GP or hospital because of worries colleagues could learn of their health problems.
Overall, two of the doctors and dentists treated were reported to to the General Medical Council (GMC), because of fears that they could be putting patients in danger.
Another six were encouraged to report themselves to the regulator.
So far the service has operated only in London but there are plans to roll it out across the country, starting initially in Newcastle.
Two thirds of the 184 treated in the first 12 months had mental health problems, while one in three who came to the specialist service had some form of addiction.
Of these 51 were alcoholics and 16 drug addicts.
Dr Gerada said:
"We are seeing every drug under the sun."The service has also treated unexpectedly high numbers of pediatricians, anesthetists and psychiatrists.
"Ketamine, methadrone, amphetamines, heroin, every drug you have ever heard of is coming through the door."
The stress of the jobs, easy access to drugs, and the extra stigma attached to psychiatrists suffering from mental health problems could be reasons for the high demand, Dr Gerada said.
More than 80 per cent of those treated for drug or alcohol addictions were now sober, the first report on the service shows.
Prof Sir Liam Donaldson, the Chief Medical Officer for England, praised the success of the scheme.
"It has uncovered problems that would otherwise not have been seen and the interventions been highly effective," he said.
What is it with Ketamine?
It is not a horse tranquilizer.
If you've had a general anaesthetic,
you've had Ketamine, along with other drugs to block the memories of your trip, which is one of the reasons you feel so shit afterwards.
That, and the fact you've had an induced NDE.
Many anaesthatists are heavily addicted to K.
"Ketamine has a wide range of effects in humans, including analgesia, anesthesia, hallucinations, elevated blood pressure, and bronchodilation.[citation needed] Ketamine is primarily used for the induction and maintenance of general anesthesia, usually in combination with some sedative drug. Other uses include sedation in intensive care, analgesia (particularly in emergency medicine), and treatment of bronchospasm. It is also a popular anesthetic in veterinary medicine."
