| ABSTRACT |
|---|
|
|
|---|
Cigarette smoking is the leading cause of preventable death in the United States. The health risks of smoking are well documented, as is the effectiveness of clinical and public health interventions to prevent and reduce smoking. However, many myths about smoking either encourage people to begin or continue smoking or deter them from quitting.
Some myths stem from a misapplied understanding of what might seem to be common sense; others are deliberately promulgated by the tobacco industry to induce peopleespecially childrento start smoking and to keep them smoking as adults. These myths undermine tobacco control. However, comprehensive tobacco control programs that include anti-smoking public education campaigns can effectively counter these myths and prevent illness and premature death.
| INTRODUCTION |
|---|
|
|
|---|
Although smoking prevalence is deceasing slowly in the United States and in some parts of the world,4,5 it is increasing sharply in other regions and among certain populations, especially in developing countries and among women.4 This is despite the fact that the health risks of smoking have been suspected and publicized since shortly after tobacco was first introduced to Europe 400 years ago,6 and these risks have been scientifically proven for at least the last half century.7
Many myths about smoking have arisenmyths that encourage people to begin or continue smoking or that deter them from quitting. These myths are believed true not only by many smokers but also by some physicians and policy makers, a fact that hinders development of effective tobacco control policy and treatment for individuals who are dependent on tobacco. This commentary reviews and rebuts 12 of the most common myths.
| MYTH #1: PEOPLE HAVE FREE CHOICE WHETHER OR NOT TO SMOKE |
|---|
|
|
|---|
Cigarettes deliver an addictive drugnicotineto the body. The tobacco industry has shown its awareness of this fact by referring to cigarettes as a "nicotine delivery device" and by acknowledging that it is the nicotine in cigarettes that makes people want to smoke.23
Children are below the age of legal consent and are not legally competent to make most decisions, including the decision about whether or not to smoke. Starting to smoke during early adolescence is associated with higher daily cigarette consumption and a lower probability of quitting as an adult.24 More than 80% of all regular smokers began smoking by the time they were 18 years old.25
Most smokers want to quit.26 However, the tobacco industry ensures that there is enough nicotine in every cigarette to keep people addicted, and production methods and chemical additives may increase nicotine content.27,28
| MYTH #2: EVERYONE KNOWS HOW BAD SMOKING IS |
|---|
|
|
|---|
In China, where more than 90% of smokers are men, fewer than 1 in 4 smokers believes smoking causes serious health problems.31 This lack of knowledge may be why smoking prevalence among Chinese immigrant men in New York City is higher than among the population as a whole. Chinese-born men who have low levels of knowledge about the harmful effects of smoking are twice as likely to smoke than those who have higher levels of knowledge.32 Knowledge may even be decreasing among some groups: one survey showed that rural smokers who were surveyed in 1997 and 1998 ascribed more positive characteristics and fewer health risks to smoking than they did during the previous decade.33
It is becoming clear that cigarettes cause disease in nearly every organ of the body (Figure 1
). In addition to lung cancer, heart disease, stroke, and emphysema, smoking has been definitively linked to other cancers (colon, cervical, kidney, pancreatic, bladder, esophageal, larynx, oral cavity and pharynx, and stomach) and acute myeloid leukemia; cardiovascular disease (atherosclerosis and abdominal aortic aneurysm); respiratory disease (impaired lung function, chronic obstructive pulmonary disease, asthma, and pneumonia); other diseases (cataracts, periodontitis, hip fractures, and peptic ulcers); general diminished health status and increased morbidity (including increased work absenteeism, increased use of medical care services, and increased risk for adverse surgical outcomes); and, among women, low bone density and osteoporosis, pregnancy complications (including low-birthweight babies, preterm delivery, fetal death, stillbirths, reduced lung function in infants, and sudden infant death syndrome), and reduced fertility.34
|
| MYTH #3: JUST A FEW CIGARETTES A DAY CANT HURT |
|---|
|
|
|---|
Cancer is the leading cause of death among smokers in the United States, with lung cancer responsible for nearly 80% of tobacco-related deaths.1 However, cardiovascular disease (all forms combined) is the leading cause of all tobacco-related mortality, including both smokers and those exposed to environmental tobacco smoke.1 Cardiovascular disease is second only to respiratory disease (i.e., chronic bronchitis and emphysema) as the leading cause of tobacco-related morbidity.2 Cardiovascular disease may be caused by exposure to carbon monoxide and other combustion products,39,40 which suggests that any "reduced risk" tobacco product that is ignited and inhaled is unlikely to significantly decrease tobacco-related illness and death from cardiovascular causes.
| MYTH #4: "LIGHT" CIGARETTES ARE LESS HARMFUL |
|---|
|
|
|---|
Fewer than 10% of smokers are aware that 1 light or ultra-light cigarette provides the same amount of tar as 1 regular cigarette, and many of these smokers say that they would be likely to quit if they learned that 1 light or ultra-light cigarette is equivalent to 1 regular cigarette.46 However, while smokers of low-tar brands are more likely to attempt to quit, they are less likely to actually quit.47
Despite decades of the tobacco industry marketing light cigarettes that are purported to have lower tar and nicotine content,48 there is no meaningful difference in smoke exposure or health risks among cigarettes with different tar and nicotine yields.49 Light cigarettes deliver the same amounts of tar, nicotine, and carbon monoxide to smokers as standard brands, partly because testing machines do not burn cigarettes the same way cigarettes burn when actually smoked by a person.27
Many low-tar, light, or ultra-light cigarette smokers unconsciously compensate for these artificially reduced machine-measured tar and nicotine levels by smoking more cigarettes, by inhaling smoke harder and deeper into the lungs, and by blocking filter ventilation holes to increase the concentration of inhaled smoke.27,50 The tobacco industry has been aware of this compensation by smokers for at least the last 3 decades.51
| MYTH #5: ITS EASY TO STOP SMOKING; IF PEOPLE WANT TO QUIT, THEY WILL |
|---|
|
|
|---|
The benefits of quitting smoking are well documented, and many people who are serious about quitting make several attempts before they quit for good.56 Most smokers want to quit and make at least 1 quit attempt each year.57 Of these, the majority attempt to stop smoking without counseling or medication,58 but only 7% of the people who try to quit without assistance succeed in stopping for 1 year or longer.59
| MYTH #6: CESSATION MEDICATIONS DONT WORK |
|---|
|
|
|---|
| MYTH #7: ONCE A SMOKER, ALWAYS A SMOKER |
|---|
|
|
|---|
| MYTH #8: SMOKERS MAY DIE EARLIER, BUT ALL THEY LOSE ARE A COUPLE OF BAD YEARS AT THE END OF LIFE |
|---|
|
|
|---|
| MYTH #9: ENVIRONMENTAL TOBACCO SMOKE MAY BE A NUISANCE, BUT IT ISNT DEADLY |
|---|
|
|
|---|
| MYTH #10: TOBACCO IS GOOD FOR THE ECONOMY |
|---|
|
|
|---|
The World Bank analyzed the net economic effect of tobacco and concluded that money not spent on cigarettes would instead be spent on other goods and services that in turn would generate other jobs and economic activity to replace any that would be lost from the tobacco industry.81 In the United States, completely eliminating tobacco from the economy would result in an estimated net increase of more than 130 000 jobs nationwide.82
In the United States, smoking causes annual economic losses of $167 billion per year (about $3650 per smoker), including health care expenses and productivity losses caused by premature death.1,5 These costs are borne by individuals and by society as a whole, and they are more than twice the $81 billion (including taxes and manufacturing and marketing costs) that US smokers spend annually on tobacco.83
The science behind smoking cessation treatment is strong, and its cost-effectiveness compares favorably with many other medical interventions.84 Businesses and health insurers have financial incentives to support cessation programs for employees: nonsmokers are more productive and miss less work than smokers do,85 and tobacco cessation coverage is one of the most cost-effective health insurance benefits an employer can provide.86
| MYTH #11: WEVE ALREADY SOLVED THE TOBACCO PROBLEM |
|---|
|
|
|---|
Although there are many other important health issues that also demand attention, one of the most critical concepts of tobacco control is that we have proven interventions. Higher taxes, expansion of smoke-free environments, increased use of cessation treatments, and public education have all been proven to decrease tobacco use.88 We cannot afford to enter into a debate as to which health problems are more important than othersall are important, and all are worthy of attention and evidence-based interventions.
| MYTH #12: THE TOBACCO INDUSTRY NO LONGER MARKETS TO KIDS OR UNDERMINES PUBLIC HEALTH EFFORTS |
|---|
|
|
|---|
Tobacco industry market leaders have recently been pressured to adopt corporate social-responsibility programs to account for and redress the tobacco industrys adverse impact on society. However, the tobacco businesswith its fiduciary responsibility to preserve and increase tobacco profitsis inherently socially irresponsible. For example, Philip Morris executives privately admit that the purposes of these programs are to protect the companys reputation, enhance shareholder value, and defend the right of adults to smoke, and that the programs do not indicate any significant change in the way Philip Morris does business.95
Cigarette advertising continues to reach children.87,96 For example, magazine ads for each of the 3 most popular brands among youths reached more than 80% of young people in the United States an average of 17 times in 2000.97 Children who own tobacco company promotional items (T-shirts, caps, etc.) are up to 7 times more likely to smoke than those who do not own these items.98
Children aged 12 to 17 yearsthe most likely age of smoking initiationare twice as likely as adults to be exposed to tobacco advertising,99 and teenagers are 3 times more sensitive to cigarette advertising than adults are.100 Depictions of smoking in movies also increases smoking among teens. Those who see movies that depict smoking are 3 times more likely to smoke than teens who do not see smoking in movies, and half of all smoking experimentation among teens has been attributed to this exposure.101 There is more smoking in movies now than at any time since 1950,102 and use of a specific cigarette brand imparts greater appeal to the brand.103 Endorsement of cigarette brandsthe use of specific brands by stars in movieshas increased 11-fold since implementation of the MSA.103 Stars who smoke onscreen strongly influence smoking behaviors among teens, and the greater the level of smoking depicted, the higher the likelihood that teens will become smokers.104 Depictions of smoking in music videos, on television, and in other media also influence the smoking behaviors of teens.105,106
Tobacco industry promotion of smoking even undermines the ability of parenting to prevent adolescents from starting to smokewhich contradicts the tobacco industrys contention that parenting practices, and not their marketing activities, are critical determinants of smoking among youths.107
| CONCLUSIONS |
|---|
|
|
|---|
Antismoking public education campaigns work, especially when they are implemented across multiple media settings and in conjunction with comprehensive tobacco control programs that include increased taxation, smoke-free workplace legislation, and cessation programs.88,108114 While government and public health agencies must take the lead, the health care system, businesses, insurers, communities, and individuals all have important roles to play in tobacco control. We must continue to find innovative ways to both communicate the facts and counter the various myths, half-truths, and lies that encourage people to start smoking and reduce their odds of quitting.
