Ln. our view, however, the f'.'=r_=gs waich are of impozzan-ce are:- (a) T--e gas/vapour ::.'-.ase is s-*-o-dn be inactive in both experizlenzs. The inhalation experiment zoduced no tumou--s in the lungs of zhe hams-.e-s (althou;:'a tumouzs in the la-77r-x were produced). (c) In both experiments sheet reconstitu:ed by certain, but not all, processes was de=onstraz~d as being less biologically active than natural tobacco.

To a large extezt this is probab--y attributable to an- overa.11 reduction in the particulate smoke intake. (e) The addition of sodium ni::-ate, in both experiments, achieved a si--iificanrt reduction 'r. biologica-I activity. f) Bota Vr-ole smoke ar-d condensate were showr- to be promoters rather than -' ---; -t.-Iators. (g) No other diseases (e.g. heazt disease) were produced by the inhallation experiment.

This theme was further develoDed in the enclosed a=t.icle in the Sunday Times on l9rh, November. Thereafter Dr. Fenner, to whom amo-,-st oz.hers the a:T-Lcle refers, was L-iterviewed on Radio 4 on 22nd Novembez. In this interview he ad=itzec that t*.-le theory was "very ill-substan~:ia-,;ed so fax".

There is reason to believe, however, that t*--e SLLnda,7 Times may be planning to publish its.own league tables for cigarettes, one based on tar and nicotime content and the other on suga:, content. J-7 is also thought not unlikely -.~--at it will recommend to the smokers amcng its readers to pay attention to the sugar rankings rat'--e-r than the tar rankings. As ZeFards z-.e si,,7nificance of sugar conten-: in cigarezzes, the Tobacco Research Council ha-z been associated -.,-,th research in this area for a =Limber of years and in its view the evidence on rtis part- iculax :)-.ob-',em is inconclusive. It is underszood that the Department of P-e--- and Social Ser-r-ces in the U.K. will, if it receives encuiries, be stating that "the evidence on suga.7 so ?ar is 4=conclu. ve T.R.C. will be fc! owi- the saa. !-me but b;-4ng careful to emD~,:as-4.~z--that it .:3 not cualified to make medical judg=en-:s.
