Select Committee on Health Minutes of Evidence



MEMORANDUM BY THE BRITISH MEDICAL ASSOCIATION

THE TOBACCO INDUSTRY (TB 25)

THE BRITISH MEDICAL ASSOCIATIONTHE VOICE OF BRITAIN'S DOCTORS

  1.  The British Medical Association is the voice of the medical profession in the UK. With a membership of more than 115,000, the BMA represents more than 80 per cent of British doctors. Every day, Britain's doctors come face to face with the suffering and death caused by smoking. In the UK, smoking accounts for more han 120,000 deaths each year—about one in every five deaths. In England alone, it has been estimated that annually, around 284,000 admissions to NHS hospitals, 8 million GP consultations and 7 million prescriptions are the result of a smoking-related illness[3]. The evidence of the BMA to the Committee reflects its members' concern for their patients, their responsibilities to the health of the nation, and their duties as public servants.

SCIENTIFIC KNOWLEDGE OF THE HARMFUL HEALTH EFFECTS OF SMOKING AND OF THE NATURE OF NICOTINE

  2.  More than 70,000 scientific papers and reports have been published on the adverse health effects of smoking[4]. Landmarks in the evolution of early scientific knowledge of the health effects of smoking are outlined in Appendix 1.

  3.  Beginning in the 1960s, a series of authoritative reports have assessed and evaluated the scientific evidence that smoking causes disease, notably:

    —  1962—Royal College of Physicians of London concludes that smoking causes lung cancer and bronchitis and probably contributes to coronary heart disease[5].

    —  1964—US Surgeon General's Report concludes that smoking causes lung and laryngeal cancer and chronic bronchitis[6].

    —  1971—Royal College of Physicians of London concludes that "if women . . . smoke the way men do, their death rate is likely to become the same[7].

    —  1977—Royal College of Physicians of London concludes that tobacco smoking is a form of drug dependence and that nicotine is probably the addictive substance involved[8].

    —  1983—UK Independent Scientific Committee on Smoking and Health concludes that smoking during pregnancy retards foetal growth[9].

    —  1986—US Surgeon General's Report concludes that nicotine addiction plays a central physiological role in smoking[10].

    —  1988—UK Independent Scientific Committee on Smoking and Health concludes that passive smoking causes lung cancer[11].

    —  1992—US Environment Protection Agency Report concludes that passive smoking causes cancer and heart disease[12].

    —  1998—UK SCOTH Report concludes that smoking is the most important cause of premature death in developed countries and accounts for one fifth of all deaths in the UK[13].

    —  1999—WHO expert consultation concludes that passive smoking causes respiratory disease and middle-ear infection, and reduces lung growth and function in children[14].

  Appendix 2 summarises selected recommendations by UK expert committees from 1962 to 1998.

  4.  Active smoking is the major cause of lung cancer, chronic bronchitis and emphysema and a major cause of heart disease and stroke. It is also causes or contributes to a plethora of other illnesses[15]. A breakdown of the death toll from smoking-induced disease in the UK is given in Appendix 3.

  5.  Passive smoking has been established as a cause of heart disease[16] and of lung cancer[17] in adults. In children, passive smoking is known to cause lower respiratory illness, reduced lung growth and middle ear disease. In addition, second-hand smoke can cause asthma, and increases the severity of the condition in children who are already affected. [18]

  6.  Nicotine is a psychoactive substance that occurs naturally in tobacco. Nicotine affects the brain, heart and endocrine system, quickening the heart rate, increasing blood pressure, and narrowing blood vessels.

  7.  Nicotine is highly addictive. Tobacco dependency is recognised as a behavioural disorder in the World Health Organisation International Classification of Diseases. [19]Habitual use of nicotine through smoking meets the key medical criteria for drug dependence, including psychoactive effects, compulsive use and self-reinforcing behaviour. Smokers experience a withdrawal syndrome when they abstain from tobacco. [20]

  8.  Nicotine addiction can rapidly become established after initiation of tobacco use. [21]As the SCOTH report concluded: "addiction to nicotine sustains cigarette smoking and is responsible for the remarkable intractability of smoking behaviour." [22]Addiction to nicotine therefore increases the smoker's vulnerability to the harm caused by long-term exposure to tobacco smoke.

TOBACCO INDUSTRY RESPONSE

  9.  The results of the body of independent scientific work on the adverse health effects of tobacco are in the public domain. They have been, and continue to be, available to the tobacco industry. In addition, the industry has had privileged access to the results of its own research programmes and of certain other research studies it has funded.

  10.  Internal documents released during legal action in the United States of America reveal that an industry-wide effort sought to create and maintain doubts about the harmful effects of tobacco. Misinformation campaigns were conducted with a view to protecting against liability actions brought by customers whose health had been damaged by smoking, avoiding government regulation, and maximizing profits by maintaining product sales. [23]

  11.  The industry conducted extensive internal research into the health effects of smoking, including analysis of cigarette smoke, identification and characterisation of cancer-inducing and tumour-promoting components, and the elucidation of the effects of smoking in animal models and in human subjects. For the most part, the results of these studies remained secret. Moreover, while publicly criticising the scientific tests being used by independent scientists in studies demonstrating the link between smoking and cancer, the industry was using these same tests to assess the mutagenic and carcinogenic effects of cigarettes. Despite the high quality of much of this research, very few of these studies were published in the scientific literature. [24]

  12.  The early response of the industry included a private research programme to investigate the possibility of producing a "safe" cigarette. [25]A certain degree of progress appears to have been made in identifying additives that might reduce the carcinogenicity of cigarettes. [26]Ultimately, however, concerns that marketing a "safe" cigarette would amount to an admission of the dangers of the existing product came to dominate, and research in this area was all but abandoned. [27]

  13.  Through front groups such as the Tobacco Industry Research Council, the industry sponsored studies by external scientists. In public, the industry maintained that the primary aim of this research was to help resolve the "controversy" surrounding tobacco and health. In private, however, the industry-sponsored research was directed with an eye to reducing the likelihood of future liability actions. Company lawyers were intimately involved in controlling industry-sponsored studies, vetoing the research agenda, drafting and approving study reports, and deciding which projects would be funded or discontinued[28].

  14.  An extensive industry research programme investigated the effects of nicotine in animals and in humans. Industry scientists and executives understood the essentially addictive nature of their product, and emphasised the key importance of nicotine in selling tobacco[29].

  15.  The tobacco industry developed technologies to allow it to control the level of nicotine in tobacco and to modify the amount of nicotine absorbed by the smoker. Patents filed in the USA document processes by which nicotine can be removed from tobacco or added to cigarettes, by spraying on tobacco, on filters or on cigarette paper[30].

CONSUMER PROTECTION

  16.  Given the weight of the scientific evidence and the scale of the suffering caused by smoking, a responsible industry would be expected to act to protect the health of its consumers. However, with regard to consumer protection, the response of the tobacco industry has been singularly inadequate. Throughout the course of the tobacco epidemic, the industry has failed in its responsibilities on numerous counts.

Failure to fully inform of the dangers of smoking

  17.  Active smoking. The record shows that while publicly denying the harmful effects of its product, the tobacco industry has been well aware of its hazards. Only recently has the tobacco industry admitted the fact that active smoking harms health. However, these admissions continue to be couched in terms that owe more to concerns of liability then to consumer welfare, and fail to address the true nature and magnitude of the health effects of smoking.

  18.  Passive smoking. The tobacco industry has yet to admit that passive smoking causes illness. Industry-wide studies on the health effects of passive smoking have been underway since the 1960s, and privately, the industry has accepted the validity of independent studies on the harmful effects of passive smoking[31]. Publicly, the same tatics used in creating a false controversy around the harmful effects of active smoking are now being used to attempt to discredit scientific knowledge of the harms caused by passive smoking.

  19.  Nicotine addiction. The tobacco industry has not accepted that nicotine is addictive. Rather, setting aside the compelling evidence that the effects of nicotine on the brain are similar to those of drugs such as heroin and cocaine[32], the industry trivialises the central physiological role of nicotine addiction in motivating smoking by comparing tobacco dependency to habits such as eating chocolate. The tobacco industry has consistently maintained that smoking is entirely a matter of "free choice".

Failure to reduce the harmfulness of their product

  20.   A less harmful cigarette? The record shows that industry research carried out into a "safe" cigarette was not implemented because of fears of product liability actions. Instead, the industry has produced "light" cigarettes, described as low in tar and nicotine. These products were developed in an effort to alleviate smoker's health concerns and marketed accordingly. However, it is clear that the stated yields of tar and nicotine on the packet bear little resemblance to those absorbed by the smoker[33]. The industry was well aware both that these cigarettes offered no real health benefits, and that marketing of "light" cigarettes would "actually retain some potential quitters in the cigarette market"[34]. Not only does the tobacco industry knowingly continue to market a product that seriously harms health, it exploits smokers' health concerns to protect company profits.

  21.   Nicotine and addiction. While the technology is available to reduce the nicotine content of cigarettes, an analysis by the USA FDA found that the levels of nicotine in cigarettes has increased rather than decreased. There is evidence that this has been made possible through the introduction of additives that increase the effective dose of nicotine delivered to the smoker, while having no effect on testing systems used by most regulatory authorities for ascertaining the levels of tar and nicotine displayed on cigarette packs[35]. The industry has failed to act to protect its customers' health by removing nicotine from its product; rather, it has used the knowledge and technology available to enhance delivery of nicotine in its products.

Failure to disclose the content of their product

  22.  Cigarette smoke contains more than 4,000 components, including many toxins, mutagens and carcinogens. The industry carried out extensive analyses of both mainstream (inhaled) and sidestream (second-hand) smoke; however, the results of this research were not made public. In addition, more than 600 substances are authorized for use in tobacco products[36]. Additives can be used to modify cigarette smoke to make it more palatable and to increase the dose of nicotine that the smoker receives. The substances added may dilate the airways, increasing exposure to the harmful effects of tobacco smoke inhalation, and may numb the throat, making it easier for novice smokers to persist with experimentation. They may also reduce the visibility and smell of second-hand smoke. The tobacco industry has failed to disclose the additives used in particular products, as well as information on their toxicity and biological effects.

Failure to compensate for damage caused to consumer

  23.  It has been estimated that during the past 50 years, almost 6 million Britons have been killed by smoking. In developed countries, the death toll is around 60 million[37]. Behind these statistics lie the enormous human suffering and distress caused by smoking-related illnesses, both fatal and non-fatal. Industry documents reveal that a central motivating factor in the response of the tobacco industry to scientific knowledge on the harmful effects of smoking has been the desire to evade product liability claims from individual consumers, health insurance companies and governments. While failing to fully inform the consumer of the true nature and risks of smoking, the tobacco industry has also failed to compensate those who suffer from smoking-induced illnesses as the result of using its product as intended.

Avoidance of regulation

  24.  The legitimate role of government in protecting the consumer and the public health includes effective regulation. Measures that have been proven to be effective in reducing the burden of avoidable disease and death from smoking and in protecting the individual from the harmful effects of smoking include effective taxation policies, bans on advertising and promotion of tobacco, and measures of the protection of non-smokers[38]. While failing to publicly accept that these measures are effective in reducing tobacco consumption, the tobacco industry has consistently resisted and campaigned against their implementation.

  25.  Regulation of the tobacco industry in the UK has often been attempted through voluntary agreements with the industry. Adherence has been assessed by the Committee for Monitoring Agreements on Tobacco Advertising and Health, composed in equal part of representatives from the tobacco industry and independent assessors. Experience shows that the effectiveness of this mechanism is limited. The procedure relies on public complaints and allows infringements of the agreements to continue while a ruling is made. Moreover, no meaningful penalty is imposed on the industry when a complaint is upheld. The introduction of a legislative ban on tobacco promotion and advertising is welcome, placing as it does the burden on the tobacco industry to comply with measures to protect the public health. Future regulatory measures to prevent tobacco-induced illness and death should be framed with this experience in mind.

Failures of global responsibility

  26.  The British-based tobacco industry operates in a global market, and is among the largest transnational cigarette manufacturers. As tobacco consumption in the UK falls, British tobacco companies are increasingly looking to market opportunities elsewhere.

  27.  If current trends continue, the global death toll from tobacco will rise from about 4 million per year in 1998 to about 10 million per year in 2030. Over 70 per cent of these deaths will occur in the developing world[39]. In 1990, smoking accounted for one in six adult deaths; in 2020, it will account for one in three[40].

  28.  While scientific knowledge on the harmful effects of smoking is accepted internationally, public knowledge of the health risks of smoking varies worldwide. In 1991, health warnings were required by 70 countries[41]. In the absence of warnings imposed by government, the tobacco industry fails to disclose even the most basic information on the health risks of smoking.

  29.  A recent report by the World Bank highlighted the economic losses associated with tobacco and concluded that an integrated strategy to address the global tobacco epidemic would mean increasing taxes, adding prominent warning labels to cigarettes, adopting comprehensive bans on advertising and promotion, and restricting smoking in workplaces and public places[42].

  30.  Internatinal action is urgently needed to curb the global tobacco epidemic. The International Convention for Tobacco Control being developed by the World Health Organisation is an international legal instrument designed to protect the public health against the global spread of tobacco. We commend the support for the Convention expressed in the recent White Paper on Tobacco[43], and urge the Government to facilitate its development and implementation.
