30- Decemlicr 15, 1970 NOTES ON VISIT TO DR. W.F. FOPBES, PROFESSOR OF STATISTICS ,,,,D C,,Ir.@Ilcr, pull A. @&.Zy, UNIVERSITY OF WATERLOO. WATERLOO, ONT. ---------------------------------------------------------- Having hcard that Dr. Forbes had set tin a research programme in the firld of Smoking and Ileallth, Mr. R.S. Wade, Imperial Tobacco Products Limited, arranged a -meeting with Dr. Forbes fnr Nlnndav. December 7. and wh-@n Mr. Wade advised me of his plans I took advantage of the opportunity to join him. We had a very pleasant meeting and an interesting discussion with Dr. Fort;-s, and also met some members of his staff; i.e., Drs. N.H. Cherry, J.C. Robinson, and Richert. Dr. Forbes has initiated the following research projects: TWIN STUDY This st:jdy is along similar lines to the Twin Study being carried ou.t by Dr. Fribeuztind Dr. Cederlof, in Sweden. In this project Dr. Forbes intends@sing 300 pairs of monozygr3tic (identical) twins drawn from the Kitchener- Waterloo area, and they wili ail be personally Interviewed as to their smoking habits and other pertinent factors. All follow-ups of these individuals will also be by personal interview and it can be expected that this project will cover quite a number of vexrs. From the viewpoint of the Industry, thig should be x very Interesting study, particularly if Dr. Forbes' findings corroborate those so C:) far rpported by Drs. Friberg and Cederlaf. -,V R.

If this view is correct, then establishin; how pe-,rle smnt^ and whether they change their smoking pattern with a modified cigarette is, from the Industry's viewpoint, most i-1--rtant. Dr. Forbes is pursuing this line of thought by givirg, individuals commercial cigarettes of known and different nicotine deliveries and checking the nicotine level to which the individual is exposed by determining the nicotine content in the butts. In connection with the foregoing, we mentioned to Dr. Forbes that tar and nicotine should not be -referred to in the same context as if they had the same physiological effect; in other words, there is a need to dissociate the two. Incidentally, these views are of significance in the context of published tar and nicotine -tab les. AROMATIC POLYCYCLTC IfYDROCARDONS The connective tissue In the lung is composer largely of collagen. Dr. Forbes has not been able to find benzpyrene or other aromatic polycyclic hydrocarbons in the lung and he is therefore interested in trying to find out who happens to these hydrocarbons.

The funds for Vie foregoing projects are basically from the University. with .0 "bly a little from the Federal Department of National Health and Welfare. Dr. Forbes brought up the subject of the tobacco industry. the Government and the universities working together in the field of Smoking and Health.,/ tie sa it] he was all in favour of this and has mentioned it to Dr. Colburn a number of times. We told Dr. Forbes that the Industry was also interested in this approach and that we have repeatedly mentioned this to the Department of National Health and Welfare from the Minister down. Dr. Forbes said that he would again write to Dr. Colburn along these lines. L. C. Uporte U-4 --4 BATCo document for Province of British Columbia 20 April 1999
