EFFECTS OF A REDUCTION IN CIGARETTE SMOKING ON MORTALITY AND MORBIDITY RATES AND ON HEALTH CARE AND SOCIAL SECURITY EXPENDITURE 1. Research studies into the health effects of smoking have almost entirely been concerned with the association between smoking and mortality. The principal studies have been made in Great Britain, the United States and Canada; the findings froin them are much in line and all show a significantly higher rate of mortality among cigarette smokers compared WiLh non-smokers. The most important study in this country is that made by Doll and Hill begun in 1951 into the smoking habits and death rates of British doctors. 2. All the major studies show that cigarvite smoking is associated with increased mortality from a range of medical conditions and that the three main conditions are lung cancer, bionchitis and coronary heart disease which together account for aboijt four-fifths of the excess mortality of smokers compared with non smokers. 3. In order to calculate the number of deaths in any period which are caused by cigarette smoking the extent to which the total deaths from the main smoking related conditions arc attributable to the habit must be known. Thc research sli.dies referred to above provide the ddta from which such attrIIAL) lability factors have been derived. These do not enable precise figures 10 IX UICUlated und this paper draws attention to factors that it has not been possible to take into account. Nevertheless the figures in the following paragraphs give a broad indication of the health consequences of cigarette smoking and the benefits that would follow a substantial reduction in cigarette consumption. 4. The Report of the Royal College of Physicians "Smoking and Health Now" presents figures on the extent to which deaths among persons aged 35 to 64 from cancer of the lung, bronchitis and coronary heart disease are caused by cigarette smoking. No specific figures are given for older persons although it was recognised that the number of deaths certified as due to the main smoking related diseases is much greater than at younger ages and that many thousands of old people who are cigarette smokers die a year or two earlier than they would have done had they not smoked. 5. The atuibutability factors used in the present calculations are shown in Table 1 and were agreed between representatives of the Department of Health and Social Security, the Office of Population Censuses and Surveys (Medical Statistics Division) and the Government Actuary's Department. Those up to the age of 64 are the same as given LN C:) c0 BATCo document for Province of British Columbia 29 October 1999 in "Sniokiiiq ajid licalth Now". The tepiewijiitivos (if flic Departments thought it icasonable EU it-NUTIC a rut-oil lioi,it at the ago of 75 despite the sudden tiansition fru.n the agc group 65 to 74 to that of 75 and over: the main reason for this was flif! difficulty iii quantifying the number of desth~ attributable to smok"fig aincing such ciderly pcrsons.

It should he noted that only the thiec main smoking refatcd conditions are included in Table 1. The othcr conditions are excluded because of the difficultv (it quantifying the extent to which they cause excess deaths among cigaiette smokers. Their exclusion and the ignoring of any deaths among persons aged 75 and over means that the number of cleaths when calculated cin the basis of Tal)lp I is understated. 7. The importance of the assumptions of attributability is shown by the following illustration. The number of deatlis due to cigarette smoking in 1968 in England and Wales among persons aged under 75 calculated oii the factors in Table I was 45.5 thousand. If the factors at age 65 to 74 are extended to the age of 75 and over the number of deathswould be 63.5 thousand. I f only the factors for cancer of the lung are extended the number of deaths would be 49.2 thousand. Studies on the economic effects of smoking have been made in Canada and attributability factors were used to estimate the number of deaths caused in that country by smoking. The application of the Canadian factors to data for England and Wales for 1968 gives 46.8 thousand deaths under age 75 compared with 45,5 thousand based on the factors in Table 1. C:D BATCo document for Province of BritiSh Columbia 29 October 1999 8. Ajiz)tlii!r factor has beeii igriored in the present calculation is any effects on licalth of tile introcILIC00.1 and growing use since tile Doll iind Hill taudy COFT11iienced uf cigarcittes with a lower tardelivery. It is icasniiable to jssun,~ that lowei- tar cigarettes havu some further effect in reducing the mcidence of lung cincer but it is not knoWr. What alluwaricc should be made for thm. However, the calculations in paragraph 10 below are based on known deaths and will thus have implicitly taken some account of the effect of the use of lower tar cigarwes and filters over tile pas, 10 to 20 years. 9. Tho ibove relates to mortality. As for morbidity there is a paucity of research data on its association with smoking and attributability factoi s catmot be calculated in the same way as for mortality. It seems reasonable to assume that the same facturs would apply for morbidity as for neurtality, that is the factors in Table 1. 10. BaTd on the factois in Table 1 (which do riot take account of ber of deaths deaths among those aged 75 and over) thi! estimatcd num which will occur in 1971 iii Great Britain clue to cicarette smoking is 52,000. This is one eviny 10 Minutes (if the night and day. Figures for 1968 show that among PL'i-sons under oic age of 75 about one in seven of all deaths and one in five of all inale deaths were clue to cigarette smoking. Amonq men a9t-d 355 to 44 onu in cight of all deaths were due to cigarette sino king, amung those agcd 45 to 64 one quarter, and those 65 to 74 one fifth. 11. ThL magnitude (if the health hazards of smoking can be underlined by a comparison of the number of dcatlis rlue to cigarette smoking and those frorn various other conditions which give rise to public concern. in 1968 some seven ttines as many people died bccause of cigarette smoking than were killed in all motor accidents (although it has to be noted that the latter iricfijdcd a higher proportion of younger persons than tht: former and also persons of 75 and over). For every five deaths among persons aged under 75 caused by cigarette smoking there were seven from all forms of cancer other than those due to smoking. Again, cleathsdue to smoking were almost twice the number from all respiratory conditions other than those caused by smoking. 12. A further hazard of cigarette sinuking is that expectant mothers who smoke regularly hive smaller babies than do those who do not smoke and in consequence there is d higher rate of mortality of the infant at birth and in early life. It has been estimated from survey research data that in 1971 some 1,500perinatal deaths will occur because of smoking.

These werc reckoned iss acute becl: and their cost was, tzkcn as the equiva!cnt proportion of the total cost of beds in acute hospitals. On that hasis the estimated cost in 1970-71 was E25 million. 15. There are but few data on the use of the general pravitioner services to assist in the stimation of the proportion of the total cost of that service and the associated pharniaccurical seivice which is inclin-A in the treatment of ccridi(ions inducod by smoking. What data are available are derived from surveys, and [lit, validity of these in reflecting the number of consuliai;ons due to pioticular conditions is open to question especially in the case of those conditioiis which in the early stages gave rise To non tpucific symptoms. 16. Thme sets of sur~(:y findings hrive been uscd in arriving at estimated cusis. The first is that trom a SUrvey over the period May 1955 to April 1956 covering 1CG qcneizil practices in England and Walus; the second frnoi 1 SUrvey of 36 practices in Exeter from 1 November, 1966, to 31 Ociober, 1E)67; and the thud from a short-term survey of one group practice in Stistol and another in Smathwick in early 197 1. The three surveys produced different results and the figure of El I million for 1970-71 Which is tdken as the rost of the general praciitiatier and pharnincrtitical services ilue to smoking is hased on the findings from the largest ind widest spread survey (inade 15 years ago) which revualed The larclast proportion of consultatio,is due to illness associated with smoking. This figure is subject to wide error but any overstatements will be ulf~iet by those health care costs, for example on home nursing, which have not been UrUL19:IL into the calculation. 17. The total annual current health care costs incurred by the hospital, family doctor and general pharmaccutical services in the treatment of smoking-induced disease is thus E36 million.

The savings would increase to about 10,000 and 20,000 a year, respectively, after 15 year,~, although these numbers would fall slightly by the and of the century.
