§ Mr. Pavitt
asked the Secretary of State for Social Services if he has yet received the evaluation on tobacco substitutes from his Scientific Liaison Committee.
§ Sir K. Joseph
No. I understand that the Committee has begun to investigate what tests are available. This is a complicated matter which will need to be looked at in some detail and I do not expect the committee to have completed its work in this area for some time—particularly since further research may be required.
