asked the Secretary of State for the Home Department whether he will add amphetamine type drugs to the list of drugs controlled by the Dangerous Drugs Act.

Substances cannot be added to the Schedule to the Dangerous Drugs Act 1965 unless the United Nations Narcotic Commission or the World Health Organisation decide or appear likely to decide that they should be controlled under the Single Convention on Narcotic Drugs 1961. Amphetamine drugs are controlled under different powers and my right hon. Friend is now reviewing the adequacy of the present controls.
