The hearing will come to order. I would like to welcome the witnesses and everyone else to this hearing of the Subcommittee on Clean Air and Nuclear Regulation ofthe Committee on Environment and Public Works. We are here today to discuss the possible effects on nonsmokers of environmental tobacco smoke, ETS, also known as secondhand smoke. Tobacco smoke directly inhaled is dangerous to the health of those who directly inhale it, to smokers. In this hearing, we are going to turn to a related public health problem, and that is the health effects on those who do not smoke but inhale environmental or secondhand tobacco smoke that is emitted by the burning end of a cigarette, pipe, or cigar, or exhaled from the lungs of smokers into the environment. We approach this subject as part of this subcommittee's interest in the quality of our indoor air, Americans spend 90 percent of our time indoors. EPA and its Science Advisory Board have consist- ently ranked indoor air pollution as one of the top four environ- mental risks to the health of the American people. Secondhand smoke is clearly a significant component ofthat threat. The Senate has passed a comprehensive indoor air quality bill, and this com- mittee has also reported our legislation that addresses the particu- lar risks ofindoor radon. The committee now has pending before it two bills introduced by Senator Lautenberg of New Jersey to restrict indoor smoking. The first bill, S. 262, would require the EPA Administrator to promul- gate guidelines for instituting a non-smoking policy in Federal buildings. The second bill, S. 1680, would require all public facili- ties to implement policies restricting smoking. That would include some private facilities, such as restaurants. (1) — The purpose of the hearing this morning is to provide the sub- committee with evidence to enable us to make informed judgments on these two bills that have been introduced by Senator Lauten- berg. According to the EPA, secondhand smoke consists ofnot only nic- otine and tar, but also about 4,000 other substances, approximately 43 of which are known or suspected carcinogens, and any of which are strong respiratory irritan—ts. According to EPA, the basic compo- nents of mainstream smoke i.e., smoke inhaled by the smoker and secondhand smoke are similar. In some cases, in fact, second- hand smoke may even be more harmful. Secondhand smoke is in the air in homes, work places, schools, restaurants, theaters, and public buildings. The Center for Disease Control tells us that 8 out of 10 nonsmokers report that they are annoyed by the smoking ofothers. But there question we are considering here today goes beyond whether secondhand smoke is an annoyance to nonsmokers. We focus this morning on the level ofhealth risks posed by secondhand smoke. We are going to examine the nature and degree of these risks as well as the assertions of some groups about scientific un- certainties or inaccuracies associated with EPA's calculation of these risks. We will begin the hearing this morning with testimony from the Administrator of EPA, Carol Browner, and Surgeon General, Dr. Elders. I am particularly pleased to welcome the Surgeon General to her first hearing before this committee. While the words "public health" do not appear in the title of our committee, the laws we enact are designed first and foremost to protect the public health of the American people. I think this committee needs to hear more frequently from the Surgeon General. I hope this is the first of many appearances in which we will benefit from your testimony. The Surgeons General of this country have been leaders in iden- tifying the health risks of smoking. In 1965, the Surgeon General's Office issued its first warning about the health hazards ofcigarette smoking and required a label to appear on every cigarette package. In 1972, the Surgeon General reviewed the health effects ofsecond- hand smoke, and in 1986, a Surgeon's Report concluded that sec- ondhand smoke can cause lung cancer in adult nonsmokers and respiratory infections in children ofparents who smoke. On March 21, 1994, just a couple ofmonths ago, five former Sur- geons General wrote: An overwhelming body of scientific evidence proves that environmental tobacco smoke poses a significant health risk for adults, children, and even the unborn. Many studies have shownthatETS is deadly. The Environmental Protection Agency has also played a leading role in examining the health effects of secondhand smoke. In Janu- ary of 1993, EPA issued a report on the respiratory health effects of secondhand smoke, which classified secondhand smoke as a known human or Group A carcinogen, a classification used only when there is strong evidence of a cause-and-effect relationship in humans between the substance examined and cancer. Only 16 other substances have been classified in this category. The EPA report estimates that secondhand smoke is responsible for approximately 3,000 lung cancer deaths annually in non- smokers in the United States and finds that infants and young children whose parents smoke are the most seriously affected by exposure. EPA estimates that passive smoking causes between 150,000 and 300,000 cases of bronchitis and pneumonia in infants and young children under 18 years of age each year, resulting in between 7,500 and 15,000 hospitalizations each year. According to EPA, passive smoking can lead to a buildup offluid in the middle ear, the single most common cause of surgery in chil- dren. EPA also estimates that between 200,000 and 1 million asth- matic children have their condition worsened each year by passive smoking, and that passive smoking can contribute to the develop- ment ofthousands ofnew asthma cases in children each year. While the EPA report only deals with the respiratory effects as- sociated with secondhand smoke, both the American Heart Associa- tion and the American Medical Association have concluded that secondhand smoke causes thousands of deaths from heart disease each year. In short, according to these studies, hundreds of thou- sands of nonsmoking Americans are being denied their ability to protect their health and the health of their children because they happen to be, work, live, eat, or shop where others are smoking. We will hear criticisms today about the scientific and statistical bases of EPA's conclusions. I intend to listen closely to these com- ments. The public has a right to expect the best scientific founda- tions for EPA's policies and actions. It is in that spirit that I look forward to the witnesses' testimony this morning. I would yield now to my colleague from New Jersey, Senator Frank Lautenberg, for an opening statement. OPENING STATEMENT OF HON. FRANK R. LAUTENBERG, U.S. SENATOR FROM THE STATE OF NEW JERSEY Senator Lautenberg. Thank you very much, Mr. Chairman. I very much appreciate your holding this hearing on the health effects of environmental tobacco smoke. The two bills I have intro- duced—S. 262 would prohibit smoking in Fede—ral buildings and S. 1680 addresses prohibition in public facilities seek to protect the American public against the dangers ofsecondhand smoke. I introduced this legislation to continue progress already made toward a smoke-free environment, which started in 1987 when I wrote the law to ban smoking on airlines. Along with Congressman Durbin in the House, we authored the smoking ban that has since made virtually all domestic flights smoke-free. Some detractors have sought to minimize this first step forward, but the airline ban introduced the segment ofthe public to the ben- efits and the comfort of a smoke-free environment. SinceNothwen, many localities have restricted smoking in various settings. it is time for the Federal Government to extend this protection to the non-smoking public in all public buildings. Last weekend the New York Times sketched out in fascinating detail the unyielding posture of an industry which has continued to withhold research findings from the Government and to market products most people believe are responsible for the deaths of 400,000 Americans each and every year. Ignoring undisputed evi- dence, it is an industry that continues to insist publicly that ciga- rettes are neither hazardous nor addictive. One w—onders, what kind of evidence d—o they need? All kinds of smokers and I used to be one of them have told me about the number of times they wanted to quit. Some of them brag that they quit 50 times, but they started 51 times. That continues to persist. I don't know what it is going to take, but we listen to them as we hold this hearing. As elected representatives of the people, the Congress has a re- sponsibility to call the industry to task to perhaps regulate its products in the public interest and to protect the non-smoking pub- lic from involuntary exposure to a Group A carcinogen. The Congress has moved toward this goal. This year, the legisla- tion I sponsored called Pro-Kids, was finally enacted. It was en- acted as part of an education objective. It requires virtually all fed- erally funded children's programs to be smoke-free, including schools, day care centers, and community health centers. However, we have more work to do. We should make all public buildings smoke-free. That is why I introduced the Smoke Free Environment Act with Congressman Waxman. This legislation would make all public buildings visited by 10 or more persons one day a week smoke-free. To the detractors of this legislation I say that if McDonald's and the Pentagon can go smoke-free, so can the Nation. Mr. Chairman, each success in moving toward a smoke-free envi- ronment has faced the obstacles set up by a well-funded, tough, stubborn tobacco lobby at each step. The tobacco industry has con- sistently distorted the scientific research on environmental tobacco smoke and the purpose of my legislation. This morning I hope we will be able to set straight the record on environmental tobacco smoke. Mr. Chairman, for those who can see this chart, a recent New York Times poll showed that 67 percent of all Americans favor a ban in smoking in all public places, which would be accomplished by enacting the Smoke-Free Environment Act. I have those results here. It is pretty dramatic. That is up, by the way, from 61 percent in 1991. The American people want to breathe cleaner air. That is what this legislation would give them. It is hard to figure out why people want to continue to ingest a substance which is a known carcinogen. And many smokers, as I said, will volunteer that they wished they had never started smok- ing and look for help in beating the addiction, an addiction that has been compared with the heroin addiction. Later this morning we are going to hear from Mr. Christopher Coggins, a research scientist from R.J. Reynolds. He will be speak- ing for the tobacco industry and I look forward to hearing his testi- mony. He has a tough job ahead of him if he denies the evidence, as his industry has in the past, that demonstrates that tobacco smoke is addictive and dangerous to others. Some of our most prominent scientists have found that smoking kills 400,000 persons per year. Our best scientists have found that environmental tobacco smoke is a Group A carcinogen, which causes 3,000 lung cancer deaths a year. The Congress and the country have an empirical basis for moving to establish a smoke- free environment for the American people.
