HC Deb 07 November 1966 vol 735 cc213-4W
Mr. Whitaker

asked the Minister of Health what evidence he has as to how the addictive effect and damage to health of tobacco compares with those of marijuana.

Mr. K. Robinson

I am advised that no comparison is possible. The effects on health from the use of tobacco are quite different from those of taking marijuana, and there is no consensus of medical opinion on the extent to which either is addictive.
