                                            CIGARETTE SMOKING RISKS ARE EXTREME

Summary

·        Risk of dying early from continuing to smoke cigarettes past 35 years of age is one in two (those affected losing on average 13 years of life).1

·        By age 35, 84% of cigarette smokers say they are addicted.2 This means many would find it difficult to stop smoking.

·        Light smoking (5-9 cigarettes a day) doubles the risk of a smoker dying early. (Figure 1)

·        Heavy smoking (20+ cigarettes /day) triples the risk.

·        The cigarette is the most dangerous tobacco product known, and the most popular. Cigarettes, including hand-rolled, account for 99% of all tobacco sold in New Zealand.3 Contrast Sweden:  48% cigarettes, 46% snus, 6% cigars, pipes and hand rolled.4

·        Hand rolled cigarettes are likely to be of at least similar toxicity.

·        Beedis (Indian hand made cigarettes) are equally as dangerous as manufactured cigarettes. Both increase the risk of heart attack four fold in middle age.5

·        Risk from tobacco is much less if smoke is not inhaled. (Example: most cigar and piper smokers, snuff taking.)

This is a credible source11 that will allow you to plug in data about yourself, a relative or a patient or client, and obtain a statistically valid and graphic sense of the difference that stopping smoking can make.

 

Health risks vary by tobacco product (see Fig.1)

Cigarette smoking risks far exceed any other type of tobacco. Never using it and seldom breathing second hand smoke is the safest way. In between are products of varying grades of risk. (Figure 1)

·         Heavy cigarette smoking triples the risk of a never smoker of dying early.6

·         Moderate or light cigarette smoking doubles the risk of a never smoker of dying early.6

·         Very light smoking still increases the risk of dying early by half.6

·         Cigar smoke inhaled into the lungs – increases the risk as for light cigarette smoking.7

·          Inhaled second hand smoke is next most dangerous – as from living with a smoker.8

·         Cigar smoke, (most do not inhale) if not inhaled, raise total death risk by 15% over that of a never-smoker.7

·         Swedish moist snuff (snus) raises total death risk by 12% over than of a never-smoker.9

·         Never smokers who live in a home where no-one smokes have the least risk.

·         Anyone combining cigarettes with other products will have an intermediate level of risk.

·         Nicotine does not add to a person’s risk.10

                CONCLUSIONS                                                          WHAT CAN BE DONE

·         Cigarettes are far more dangerous than any other tobacco product.

·         Light cigarette smoking (5-9 cigarettes per day) doubles the risk of dying early, compared with a never smoker. Light smoking being common nowadays, most cigarette deaths occur among light smokers.

·         The risks of snus or cigar smoke in the mouth (not the lungs) are less than the risks of living with a smoker (and inhaling second hand smoke)

·         The risks of snuff or even chewing on a lit cigar are much less than the risk of smoking, provided no smoke is inhaled.

·         The safest thing to do is to not smoke at all.

·         Using nicotine gum for 5 years is a safe alternative to smoking.

 

The Minister of Finance can encourage the switch away from cigarettes by

·        levying excise according to the risk from using each type of tobacco product.

·        Steadily raising the tax on cigarettes, particularly on hand rolled cigarettes. The Royal Australasian College of Physicians recommends a steady annual increase (of 2 to 5 percent every year) above the level of inflation. www.racp.edu.au/hpu/policy/tobacco/tobacco_policy.pdf

·        Lifting the ban on the sale of low risk oral snuffs will enable smokers to avoid lung cancer and smokers’ lung (emphysema)

Government needs to regulate cigarette manufacture to require charcoal filtering of toxicants in cigarette smoke. This may reduce the amount of poisonous gases inhaled by some smokers. See www.smokeless.org.nz/lesstoxic.htm  However no one can claim that such filters reduce the risk of early death.
