t I , CONFIDENTIAL H. Wajueham April 20, 1962 C. V. Mnce Poliey regarding the "Tar Derby*. Here are ay thoughts on a policy the evmpany aSght follow as a result of the reopening of the smoking and health quostion in Qreat Britain. Pirst, since thare is a chance, slight though it may be, that excessive cigarette amoking may lead to a greater incidence of de®eaerative diseases In tuaoans, and thl.z 2n turn to a lessening in ttue use of oigarettes, I thiasc we should di _ our busiaess at a mars rapid rate than ar are doing. Second, it the "Tar DerbT* starts up again ia the Daited States, I think we should try to b.- the first to marScet a cigaratte •-- deliveriag considerabls less* (than the average delivered byr all the major filter oigaretiyes aa tins market today) of one or more of those subotanaes (whether in particulate or In the gas phaae) that have been reported to be lrritatiag to the hwaan :kia or mucous membrane. Zf this eanaot be carried out by selective filtration (xhetler f:aa •tho particulate or from the gaa phase), but only by acroas-the-board filtration, then it is suMeated that aoast exotic flavor such as menthol be added to take the place of the reduced tobacco flavor which may eure17 reault trom such high filtration. I do not think it i.a worthsthile reduaing tlse delivered TPt4 In an across-the-board fashion iam].esa we have a pnrpose In aind• such as, for exaaple, it i8 the only method we have for reducing one of those Srritating in- gredienta In the smoke. There may be some aubstances we could re- aove selectively In the gan•phase after an across-the-board reduction 3a TPM if we placed the gas phase filter behind the TP.1-i fater so as to ainiaize the poisoning of the former by the TPt•1. tiere are turtlsar sumestions one how to produce a eigaret te rrith less irritating amoke. Let's apeed up our activities on the solvent extraction of tobacco for the purpose of reducing the quantity of TPM, nicotine and gas phase rsaterizla delivered froa the cigarette blend. This could !-+ lead to a means of augmenting what rsay be achieved by the methods deacribed In the preceding paraQeaph. c 0 Let's compare the quantities of the irritating substances },."' (both in the partioulate and in the gas phase of the smoke) aaong the ~ different grades and the different types of tobaccos used in the t: typical ciGaretta blend for the pua•pose of discovering which 'of these .o produces the lcast L^ritating substances. This knowledge could be used to augment that given In psragraphs three and four. F-A - • ..,....,....~.... ~ rl.qloil I CTR HN 026397

Dr. H. Wakeham 2 ADacil 20, 1962 Firmlly, let'a haraten our search for an additive (oatalyst) that might be incorporated into the ciguoetta blend tor the Durpose of reduolao the irritating substances in the amoice. think.
