HC Deb 24 February 1969 vol 778 c222W
Dr. Gray

asked the Secretary of State for the Home Department why he has allowed cough linctus containing morphine hydrochloride to be obtained without medical prescription.

Mr. Elystan Morgan

Because our law reflects the provisions of the United Nations Single Convention on Narcotic Drugs, 1961, which does not require preparations of this kind to be available only on prescription.
