Smoke warnings saved millions of lives, report shows

Historic smoking report marks 50th anniversary

Fifty years ago, ashtrays seemed to be on every table and desk. Athletes and even Fred Flintstone endorsed cigarettes in TV commercials. Smoke hung in the air in restaurants, offices and airplane cabins. More than 42 percent of U.S. adults smoked, and there was a good chance your doctor was among them.
Cigarette smoke exposure can cause
cancer, health experts say.

The turning point came on Jan. 11, 1964. It was on that Saturday morning that U.S. Surgeon General Luther Terry released an emphatic and authoritative report that said smoking causes illness and death — and the government should do something about it.

In the decades that followed, warning labels were put on cigarette packs, cigarette commercials were banned, taxes were raised, and new restrictions were placed on where people could light up.

"It was the beginning," said Kenneth Warner, a University of Michigan public health professor who is a leading authority on smoking and health.

It was not the end. While the U.S. smoking rate has fallen by more than half to 18 percent, that still translates to more than 43 million smokers. Smoking is still far and away the leading preventable cause of death in the United States Some experts predict large numbers of Americans will puff away for decades to come.

Nevertheless, the Terry report has been called one of the most important documents in U.S. public health history, and on its 50th anniversary, officials are not only rolling out new anti-smoking campaigns but reflecting on what the nation did right that day.

The report's bottom-line message was hardly revolutionary. Since 1950, head-turning studies that found higher rates of lung cancer in heavy smokers had been appearing in medical journals. A widely read article in Reader's Digest in 1952, "Cancer by the Carton," contributed to the largest drop in cigarette consumption since the Depression. In 1954, the American Cancer Society announced that smokers had a higher cancer risk.

But the tobacco industry fought back. Manufacturers came out with cigarettes with filters that they claimed would trap toxins before they settled into smokers' lungs. And in 1954, they placed a full-page ad in hundreds of newspapers in which they argued that research linking their products and cancer was inconclusive.

Cigarette sales rebounded

It was a brilliant counter-offensive that left physicians and the public unsure how dangerous smoking really was. Cigarette sales rebounded.

After Terry's report, health officials realized it would take more than one report.

In 1965, Congress required cigarette packs to carry warning labels. Two years later, the Federal Communications Commission ordered TV and radio stations to provide free air time for antismoking public service announcements. Cigarette commercials were banned in 1971.

The 1970s also saw the birth of a movement to protect nonsmokers from cigarette fumes, with no-smoking sections on airplanes, in restaurants and in other places. Those eventually gave way to complete smoking bans. Cigarette machines disappeared, cigarette taxes rose, and restrictions on the sale of cigarettes to minors got tougher.

Tobacco companies also came under increasing legal attack. In the biggest case of them all, more than 40 states brought lawsuits demanding compensation for the costs of treating smoking-related illnesses. The tobacco industry settled in 1998 by agreeing to pay about $200 billion and curtail marketing of cigarettes to youths.

Smoking today:
43M -- Americans who smoke today.
8.6M -- Americans living with a serious illness caused by smoking.
443,000 -- Americans who die prematurely each year from smoking or exposure to secondhand smoke.

In 1998, while the settlement was being completed, tobacco executives appeared before Congress and publicly acknowledged for the first time that their products can cause lung cancer and be addictive.

Experts agree that the Terry report clearly triggered decades of changes that whittled the smoking rate down. But it was based on data that was already out there. Why, then, did it make such a difference?

For one thing, the drumbeat about the dangers of smoking was getting louder in 1964, experts said. But the way the committee was assembled and the carefully neutral manner in which it reached its conclusion were at least as important, said Dr. Tim McAfee, director of the Office on Smoking and Health at the federal Centers for Disease Control and Prevention.

At the same time, he and others said any celebration of the anniversary must be tempered by the size of the problem that still exists.

Each year, an estimated 443,000 people die prematurely from smoking or exposure to secondhand smoke, and 8.6 million live with a serious illness caused by smoking, according to the CDC.

Secondhand smoke responsible for $6.6 billion in lost productivity

Secondhand smoke is accountable for 42,000 deaths annually to nonsmokers in the United States, including nearly 900 infants, according to a new UCSF study.

Altogether, annual deaths from secondhand smoke represent nearly 600,000 years of potential life lost – an average of 14.2 years per person – and $6.6 billion in lost productivity, amounting to $158,000 per death, report the researchers.

The study, which involved the first use of a biomarker to gauge the physical and economic impacts of cigarette smoke, revealed that secondhand smoke exposure disproportionately affects African Americans, especially black infants.

The new research reveals that despite public health efforts to reduce tobacco use, secondhand smoke continues to take a grievous toll on nonsmokers.

The study was published in the American Journal of Public Health.

“In general, fewer people are smoking and many have made lifestyle changes, but our research shows that the impacts of secondhand smoke are nonetheless very large,” said lead author Wendy Max, PhD, professor of health economics at the UCSF School of Nursing and co-director of the UCSF Institute for Health & Aging. “The availability of information on biomarker-measured exposure allows us to more accurately assess the impact of secondhand smoke exposure on health and productivity. The impact is particularly great for communities of color.”

Exposure to secondhand smoke is linked to a number of fatal illnesses including heart and lung disease, as well as conditions affecting newborns such as low birth weight and respiratory distress syndrome.

About a decade ago, the federal Centers for Disease Control and Prevention – using data from the California Environmental Protection Agency – reported that 49,400 adults died annually as a result of secondhand smoke exposure. Additionally, the CDC reported that 776 infants annually died as a result of maternal exposure in utero.

Those widely-cited statistics relied on self-reporting to gauge the impact of secondhand smoke.

The new study led by UCSF shows that the statistics on fatalities resulting from for ischemic heart disease are 25 percent lower than previously reported (34,000 deaths compared to 46,000), but nearly twice as high for lung cancer deaths (7,333 deaths compared to 3,400). The new study also shows higher infant mortality (863 deaths compared to 776).

The researchers used serum cotinine – a biomarker which detects the chemical consequences of exposure to tobacco smoke in the bloodstream - to measure exposure to secondhand smoke. That measurement reflects secondhand exposure in all settings, not just home or work, the authors wrote.

The scientists gauged the economic implications – years of potential life lost and the value of lost productivity – on different racial and ethnic groups.

Mortality was measured in two conditions for adults: lung cancer and ischemic heart disease; and four conditions for infants: sudden infant death syndrome, low birth weight, respiratory distress syndrome, and other respiratory conditions of newborns.

Of the 42,000 total deaths resulting from secondhand smoke, 80 percent were white, 13 percent were black, and 4 percent were Hispanic. The vast majority of deaths were caused by ischemic heart disease. Black babies accounted for a startling high 24 percent to 36 percent of all infant deaths from secondhand smoke exposure, the researchers reported, although blacks represented only 13 percent of the total U.S. population in 2006.

The value of lost productivity per death was highest among blacks ($238,000) and Hispanics ($193,000).

“Black adults had significantly greater exposure rates than did whites in all age groups,” the authors wrote. “The highest secondhand smoke exposure was for black men aged 45 to 64 years, followed by black men age 20 to 44 years. Black women aged 20 to 44 years had a higher exposure rate (62.3 percent) than did any other women.”

“Our study probably under-estimates the true economic impact of secondhand smoke on mortality,” said Max. “The toll is substantial, with communities of color having the greatest losses. Interventions need to be designed to reduce the health and economic burden of smoking on smokers and nonsmokers alike, and on particularly vulnerable groups.”
