The committee responsible under the United Nations for dealing with the international control of narcotic drugs have decided to introduce a new convention so as to bring under control certain synthetic drugs, especially of the amidine series, which are capable of producing addiction, and which are not covered by the convention of July 13, 1931, as amended on December 11, 1946. Under this new convention the manufacture of these drugs, including their preparations and compounds, will be limited by international agreement to the world's legitimate requirements for medicinal and scientific purposes, and their distribution will also be regulated accordingly. The Drugs Act, 1940 (Act No. XXIII of 1940), which extends to the whole of India except the State of Jammu and Kashmir, was passed by the Indian Legislature for the purpose of regulating the import into, and the manufacture, distribution, and sale in India of drugs, such as (1) patent or proprietary medicines, (2) substances commonly known as vaccines, sera, toxins, toxoids, antitoxins, and antigens and biological products of such nature, (3) vitamins, hormones and analogous products, and (4) other drugs, which are meant for the internal and external use of human beings or animals and are also intended to be used for or in the treatment, mitigation or prevention of disease in human beings or animals. This Act is not appli- cable to medicines and substances exclusively used or prepared for use in accordance with the Ayurvedic or Unani systems of medicine. The Drugs Act, 1940, has been recently amended by the Drugs (Amend- ment) Act, 1955, which came into force on 15th April 1955, by virtue of which the Act covers in addition to the above, the following : — " Such substances (other than food) intended to affect the structure or any function of human body or intended to be used for the destruction of verm ins or insects which cause disease in human beings or animals, as may be £»pe€ified from time to time by the Central Government by notification in the Official Gazette." Hence insecticides, disinfectants and contraceptives which were so far exempted from the purview of this Act are brought into control.
