In the United Kingdom the Dangerous Drugs Act 1920 is an Act which attempted to make drug addiction and its treatment by doctors a penal matter and to take away the established view up to then held generally by the medical profession, that drug addiction was a disease and should be treated accordingly. The former was the view held by the then Assistant Under Secretary of State, Malcolm Delevingne.[1]
The Home Office was charged with implementing the Act[2]
The Act also said that the export, import, sale, distribution or possession of barbiturates, had to be licenced or authorised by the Home Secretary. This proviso also applied to dilutions of cocaine and morphine, as defined in the lower limits set by the Hague Convention.
The Home Office, in consultation with the Ministry of Health, as a result of this Act, produced a series of memorandi for doctors and dentists to explain the requirements of the Act. These were know DD 101's (Memorandi as to the Duties of Doctors and Dentists) These were distributed to doctors, although the memorandi never had any statuary power.[3] One particular memorandum, in 1938, added, for the first time, that maintenance of addicts if only for the 'gratification of addiction is not regarded as a medical need'[4]
