There is, however, an obligation imposed on every doctor by the Misuse of Drugs (Notification of and Supply to Addicts) Regulations 1973 to notify the Chief Medical Officer at the Home Office of details of persons whom he considers, or has reasonable grounds to suspect, to be addicted to any one, or more, of 14 specified narcotic drugs. The number of narcotic drug addicts known to the Home Office at 31 December each year was published in tables 7 to 11 of Home Office statistical bulletin, Issue No. 6/79, a copy of which has been placed in the Library of the House.
