Cigarettes and the US Public Health Service in the 1950s

Initiating Pharmacologic Treatment in Tobacco-Dependent Adults

There is a strong evidence base for the use of existing pharmacotherapies to support tobacco cessation, alone or in combination, ideally with concurrent behavioral interventions. Future pharmacotherapies under development may assist in the most refractory cases. Incorporating current and future therapies into a longitudinal chronic care model for tobacco dependence will help a diverse range of patients achieve independence from nicotine addiction.

The Development of Global Cancer Research at the United States National Cancer Institute

International research and collaboration has been a part of the National Cancer Institute's (NCI) mission since its creation in 1937. Early on, efforts were limited to international exchange of information to ensure that U.S. cancer patients could benefit from advances in other countries. As NCI's research grant portfolio grew in the 1950s, it included a modest number of grants to foreign institutions, primarily in the U.K. and Europe. In the 1960s, the development of geographic pathology, which aimed to study cancer etiology through variations in cancer incidence and risk factors, led to an increase in NCI funded international research, including research in low- and middle-income countries. In this paper, we review key international research programs, focusing particularly on the first fifty years of NCI history. The first NCI-led overseas research programs, established in the 1960s in Ghana and Uganda, generated influential research but also struggled with logistical challenges and political instability. The 1971 National Cancer Act was followed by the creation of a number of bilateral agreements with foreign governments, including China, Japan, and Russia, to support cooperation in technology and medicine. While these agreements were broad without specific scientific goals, they provided an important mechanism for sustained collaborations in specific areas. With the creation of the NCI Center for Global Health in 2011, NCI's global cancer research efforts gained sustained focus. While the global cancer burden has evolved over time, increasingly impacting low- and middle-income countries, NCI's role in global cancer research remains more important than ever.

Measuring perceptions related to e-cigarettes: Important principles and next steps to enhance study validity

Measuring perceptions associated with e-cigarette use can provide valuable information to help explain why youth and adults initiate and continue to use e-cigarettes. However, given the complexity of e-cigarette devices and their continuing evolution, measures of perceptions of this product have varied greatly. Our goal, as members of the working group on e-cigarette measurement within the Tobacco Centers of Regulatory Science (TCORS) network, is to provide guidance to researchers developing surveys concerning e-cigarette perceptions. We surveyed the 14 TCORS sites and received and reviewed 371 e-cigarette perception items from seven sites. We categorized the items based on types of perceptions asked, and identified measurement approaches that could enhance data validity and approaches that researchers may consider avoiding. The committee provides suggestions in four areas: (1) perceptions of benefits, (2) harm perceptions, (3) addiction perceptions, and (4) perceptions of social norms. Across these 4 areas, the most appropriate way to assess e-cigarette perceptions depends largely on study aims. The type and number of items used to examine e-cigarette perceptions will also vary depending on respondents' e-cigarette experience (i.e., user vs. non-user), level of experience (e.g., experimental vs. established), type of e-cigarette device (e.g., cig-a-like, mod), and age. Continuous formative work is critical to adequately capture perceptions in response to the rapidly changing e-cigarette landscape. Most important, it is imperative to consider the unique perceptual aspects of e-cigarettes, building on the conventional cigarette literature as appropriate, but not relying on existing conventional cigarette perception items without adjustment.

Chapter 8: The FHCRC lung cancer model

As a member of the Cancer Intervention and Surveillance Modeling Network (CISNET), the lung cancer (LC) group at Fred Hutchinson Cancer Research Center (FHCRC) developed a model for evaluating U.S. lung cancer mortality trends and the impact of changing tobacco consumption. Model components include a biologically based two-stage clonal expansion (TSCE) model; a smoking simulator to generate smoking histories and other cause mortality; and adjustments for period and birth cohort to improve calibration to U.S. LC mortality. The TSCE model was first calibrated to five substantial cohorts: British doctors, American Cancer Society CPS-I and CPS-II, Health Professionals' Follow-Up Study (HPFS), and Nurses' Health Study (NHS). The NHS and HPFS cohorts included the most detailed smoking histories and were chosen to represent the effects of smoking on U.S. LC mortality. The calibrated TSCE model and smoking simulator were used to simulate U.S. LC mortality. Further adjustments were necessary to account for unknown factors. This provided excellent fits between simulated and observed U.S. LC mortality for ages 30-84 and calendar years 1975-2000. The FHCRC LC model may be used to study the effects of public health information on U.S. LC trends and the impact of tobacco control policy. For example, we estimated that over 500,000 males and 200,000 females avoided LC death between 1975 and 2000 due to increasing awareness since the mid 1950s of the harmful effects of smoking. We estimated that 1.1 million male and 0.6 million female LC deaths were avoidable if smokers quit smoking in 1965.

Culture change in addictions treatment: a targeted training and technical assistance initiative affects tobacco-related attitudes and beliefs in addiction treatment settings

Targeted training and technical assistance can have a major impact on the attitudes and beliefs of addiction service providers with respect to the treatment of tobacco dependency. Major gains have been made with the general public since the mid-1960s with respect to the reduction of tobacco use behavior and tobacco-related diseases. Tobacco use continues to be a major public health problem, and tobacco control initiatives are significantly affecting public attitudes and norms regarding tobacco use. There is, however, a specific population that has not benefited from these gains and, in fact, has been encouraged to continue smoking rather than make an attempt to quit. Individuals with a substance use disorder and/or mental health disorder have a much higher percentage of tobacco use than the general population, resulting in major health disparities. The addiction treatment and recovery community has lagged behind the general public in addressing tobacco use. New York State's project, "Integrating Tobacco Use Interventions Into Chemical Dependence Services," is a model that demonstrates how innovative regulations, and training and technical assistance developed specifically for addiction service providers, can initiate culture change with respect to tobacco use within addiction treatment settings, resulting in improved treatment outcomes and longer term stable recovery.

Changes in skin tanning attitudes. Fashion articles and advertisements in the early 20th century

Historical reviews suggest that tanning first became fashionable in the 1920s or 1930s. To quantitatively and qualitatively examine changes in tanning attitudes portrayed in the popular women's press during the early 20th century, we reviewed summer issues of Vogue and Harper's Bazaar for the years 1920, 1927, 1928, and 1929. We examined these issues for articles and advertisements promoting skin tanning or skin bleaching and protection. We found that articles and advertisements promoting the fashionable aspects of tanned skin were more numerous in 1928 and 1929 than in 1927 and 1920, whereas those promoting pale skin (by bleaching or protection) were less numerous. These findings demonstrate a clear shift in attitudes toward tanned skin during this period.

A Turning Point for Conflicts of Interest: The Controversy Over the National Academy of Sciences' First Conflicts of Interest Disclosure Policy

Conflicts of interest policies have become a part of the fabric of the conduct of biomedical research, yet such concerns are relatively recent history. Until the 1960s, concerns about conflicts of interest were confined to scientists who served as government advisors and contractors. However, in the 1970s, as a range of environmental and consumer safety issues gained public attention, the conclusions of researchers frequently came under attack because of concerns about experts' financial ties to private industry. These debates typically focused on evaluating potential carcinogens in the environment. In response, the National Academy of Sciences (NAS) developed its first conflict of interest policy, requiring committee members to disclose any “potential sources of bias” that “others might deem prejudicial.” Scientists universally opposed the policy, however, for a range of reasons—while some argued that all experienced and knowledgeable experts were inherently conflicted, others were offended at the suggestion that any expert could be biased. Despite the controversy, the disclosure policy remained in place and became a model for subsequent professional and institutional policies in the biomedical sciences. However, although disclosure policies have become standard at academic medical centers and for publications in scientific journals, clinical researchers have continued to debate the content of these policies and the need for additional protections beyond disclosure. In the absence of a definitive standard, this historical case study can substantially inform ongoing discussion on conflicts of interest in clinical research.

Historians' testimony on "common knowledge" of the risks of tobacco use: a review and analysis of experts testifying on behalf of cigarette manufacturers in civil litigation

A qualitative analysis of the trial and deposition testimony of professional historians who have testified on behalf of the tobacco industry shows that defence historians present a view of past knowledge about tobacco in which the public was frequently warned that cigarettes were both deadly and addictive over the broad historical period. While defence historians testify to conducting significant levels of independent research, they also draw upon a common body of research conducted by industry counsel to support its litigation efforts. Defence historians unduly limit their research materials, ignoring industry records and, therefore, critically undermine their ability to evaluate industry activity in the smoking and health controversy as it unfolded in historical time. A consequence is that defence historians present a skewed history of the cigarette in which the tobacco industry all but ceases to exist.

What are the policy implications of the evidence on cannabis and psychosis?

OBJECTIVE

To explore the implications for mental health services, for health education about the risks of cannabis use, and for public policy toward cannabis use of observational evidence that cannabis use is a contributory cause of psychosis.

METHOD

Using comparative analyses of similar evidence for the harmful effects of alcohol, tobacco, and amphetamine use, we considered the relation between observational evidence and action on cannabis. We examined arguments on the grounds of public health prudence for discouraging cannabis use by young individuals. With the assumption that the relation may be causal, we considered recommendations for policy in mental health services, health education, and public policy toward cannabis.

RESULTS

The observational evidence and biological plausibility of the hypothesis that cannabis is a contributory cause of psychosis is at least as strong as evidence for causal relations between heavy alcohol and amphetamine use and psychosis. On public health grounds, there is a good case for discouraging cannabis use among adolescents and young adults. It remains uncertain how best to discourage use and at whom campaigns to reduce cannabis use should be targeted.

CONCLUSIONS

We should discourage young adults seeking treatment in mental health services from using cannabis and inform them of the probable mental health risks of cannabis use, especially of early and frequent use. We must exercise caution in liberalizing cannabis laws in ways that may increase young individuals' access to cannabis, decrease their age of first use, or increase their frequency of cannabis use. We should consider the feasibility of reducing the availability of high-potency cannabis products.

Smoking and the new health education in Britain 1950s-1970s

Advertising has a dual function for British public health. Control or prohibition of mass advertising detrimental to health is a central objective for public health in Britain. Use of mass advertising has also been a more general public health strategy, such as during the initial government responses to HIV/AIDS in the 1980s. We trace the initial significance of mass advertising in public health in Britain in the postwar decades up to the 1970s, identifying smoking as the key issue that helped to define this new approach. This approach drew from road safety and drink driving models, US advertising theory, relocation of health education within the central government, the arrival of mass consumption, and the rise of the "new public health" agenda.

Prices, policies and youth smoking, May 2001

Youth smoking continues to be an important public health problem. Many policy tools designed to reduce youth smoking are based on economic principles. This paper describes the economic and policy context of tobacco use aiming at reducing youth smoking and explains the economic rationale for tobacco control tools such as excise tax and price, clean indoor air laws, youth access laws and the broad provision of health information to the public. An overview of economic models of addiction provides the framework for empirical analysis of the impact of these policies. This is followed by a summary of the empirical evidence of the effectiveness of various tobacco control tools that are primarily economic in nature. The most consistent finding in this literature is that higher cigarette prices discourage youth smoking. Compared to the effects of cigarette taxation and price on youth smoking, the evidence on the effectiveness of the youth access laws and clean indoor air laws are still mixed and inconclusive. More research is needed to address issues such as: (1) the effects of gender, age, race and socio-economic status on the relationship between tobacco control policies and youth smoking; (2) better measurement of the outcome variables to account for the multi-dimensional nature of dependence; and (3) the effects of excise taxes and other tobacco control policies with regard to a host of dimensions of smoking such as initiation, cessation, and more generally the trajectories of tobacco use that would include patterns of progression, maintenance, regression, cessation, and relapse. More frequently collected longitudinal data than those currently available are needed to address the above issues. Understanding smoking behavior cannot be achieved without incorporating familial and other social contexts.

The history of uranium mining and the Navajo people

From World War II until 1971, the government was the sole purchaser of uranium ore in the United States. Uranium mining occurred mostly in the southwestern United States and drew many Native Americans and others into work in the mines and mills. Despite a long and well-developed understanding, based on the European experience earlier in the century, that uranium mining led to high rates of lung cancer, few protections were provided for US miners before 1962 and their adoption after that time was slow and incomplete. The resulting high rates of illness among miners led in 1990 to passage of the Radiation Exposure Compensation Act.
