HC Deb 01 August 1963 vol 682 c124W
46. Dr. D. Johnson

asked the Secretary of State for the Home Department if he is aware that the plant Morning Glory, Ipomoea purpurea, growing in Great Britain, possesses as a property of its seeds a mental poison which is a potential drug of addiction; and whether he will make an investigation, with a view to taking steps to prevent the use of this drug.

Mr. Brooke

I am aware that reports have appeared in the Press that the seeds of Morning Glory grown in North America have been found to contain a hallucinogenic drug. There is no evidence that seeds of this plant sold in this country contain the drug, but I am making further inquiries.
