HC Deb 23 May 1972 vol 837 c329W
Mr. Deakins

asked the Secretary of State for Social Services what evidence his Department has which suggests that smoking cannabis is as dangerous to health as smoking tobacco.

Sir K. Joseph

More study is still needed about the smoking of cannabis and its effects. But the types of risk involved are essentially different from the risks of smoking cigarettes, and the two cannot meaningfully be compared.

Mr. Deakins

asked the Secretary of State for Social Services what research his Department is undertaking into the health hazards of smoking cannabis.

Sir K. Joseph

None at present.
