If advocates of bans on tobacco advertising had their complete way, most would prohibit this product outright. But this is
not (yet) politically feasible. Instead, they have focussed their efforts on restricting information flows about this product.
They rely on the doctrine that free speech rights apply only indirectly, if at all, to such matters of commerce. In this paper
several arguments in behalf of bans on tobacco advertising are considered, and all are found invalid.

Assessing Exposures to Environmental Tobacco Smoke 总被引:1,自引:0,他引:1

The combustion of tobacco indoors results in the emission of a wide range of air contaminants that are associated with a variety of acute and chronic health and comfort effects. Exposures to environmental tobacco smoke (ETS) are assessed for epidemiologic studies and risk assessment and risk management applications. An individual's or population's exposure to ETS can be assessed by direct methods, which employ personal air monitoring and biomarkers, and indirect methods, which utilize various degrees of microenvironmental measurements of spaces, models, and questionnaires in combination with time-activity information. The major issues related to assessing exposures to ETS are summarized and discussed, including the physical-chemical nature of ETS air contaminants, use of proxy air contaminants to represent ETS, use of biomarkers, models for estimating ETS concentrations indoors, and the application of questionnaires. 相似文献

After an extensive review and analysis of the scientific evidence on the respiratory health effects of passive smoking, the U.S. Environmental Protection Agency concluded that environmental tobacco smoke causes lung cancer in adult nonsmokers and increases the risk of a variety of non-cancer respiratory disorders, especially in children. This article is a response to claims in Dr. Gio Gori's article "Policy Against Science: The Case of Environmental Tobacco Smoke," appearing in the same issue of this journal, that such conclusions are unwarranted. This response focuses only on the respiratory health effects of environmental tobacco smoke. 相似文献

Comparing the harmful health effects related to two different tobacco products by applying common risk assessment methods to each individual compound is problematic. We developed a method that circumvents some of these problems by focusing on the change in cumulative exposure (CCE) of the compounds emitted by the two products considered. The method consists of six steps. The first three steps encompass dose-response analysis of cancer data, resulting in relative potency factors with confidence intervals. The fourth step evaluates emission data, resulting in confidence intervals for the expected emission of each compound. The fifth step calculates the change in CCE, probabilistically, resulting in an uncertainty range for the CCE. The sixth step estimates the associated health impact by combining the CCE with relevant dose-response information. As an illustrative case study, we applied the method to eight carcinogens occurring both in the emissions of heated tobacco products (HTPs), a novel class of tobacco products, and tobacco smoke. The CCE was estimated to be 10- to 25-fold lower when using HTPs instead of cigarettes. Such a change indicates a substantially smaller reduction in expected life span, based on available dose-response information in smokers. However, this is a preliminary conclusion, as only eight carcinogens were considered so far. Furthermore, an unfavorable health impact related to HTPs remains as compared to complete abstinence. Our method results in useful information that may help policy makers in better understanding the potential health impact of new tobacco and related products. A similar approach can be used to compare the carcinogenicity of other mixtures. 相似文献

This study investigated public trust and its determinants concerning the government's control of tobacco in Japan. We focused on the two issues of government policies to ban smoking by minors and increase taxes on tobacco. We conducted a questionnaire survey in which respondents were asked to assess their trust in the government, the government's fairness and competency, and their value similarity with the government. One thousand three hundred and ninety-four respondents agreed to participate in the survey out of 2,600 randomly sampled adults over 20 years old from all over Japan. The results of multiple regression analysis confirmed that value similarity is the strongest predictor of public trust in the government. On the affirmatively supported issue of prohibiting smoking among minors, the results further indicated that assessment of competency is a stronger predictor than assessment of fairness. In contrast, assessment of fairness is a stronger predictor than assessment of competency for the still divided issue of increasing tobacco tax. Respondents who had low concern and had not formed clear opinions on the issues showed a weak link between assessment of value similarity and trust. Based on these findings, we considered the implications for the government's implementation of tobacco controls. 相似文献

Environmental Tobacco Smoke: Exposure-Response Relationships in Epidemiologic Studies 总被引:1,自引:0,他引:1
Demonstration of a dose-response relationship for environmental tobacco smoke (ETS) is an important indication of causality. Central to the analysis and interpretation of dose-response relations as described in epidemiological studies is the relationship between dose and exposure. It must be recognized that in studies of ETS we have only surrogate measures of dose, and these surrogate measures (based on exposure) are imperfect. The question-based measures of ETS exposure generally have not been standardized, may have limited validity and reliability, and cannot comprehensively describe total ETS exposure, exposure to individual ETS components, nor doses of biologically relevant agents at target sites. Nevertheless, useful data have been yielded in epidemiologic studies linking ETS exposure to increased respiratory infection and symptoms, reduced lung growth in children, and increased lung cancer in nonsmoking adults. The more consistent exposure-response data for studies on acute health in children may reflect the greater difficulty in measuring exposure in studies of chronic health in adults. 相似文献

The 16-City Study analyzed for gas-phase environmental tobacco smoke (ETS) constituents (nicotine, 3-ethenyl pyridine [3-EP], and myosmine) and for particulate-phase constituents (respirable particulate matter [RSP], ultraviolet-absorbing particulate matter [UVPM], fluorescing particulate matter [FPM], scopoletin, and solanesol). In this second of three articles, we discuss the merits of each constituent as a marker for ETS and report pair-wise comparisons of the markers. Neither nicotine nor UVPM were good predictors for RSP. However, nicotine and UVPM were good qualitative predictors of each other. Nicotine was correlated with other gas-phase constituents. Comparisons between UVPM and other particulate-phase constituents were performed. Its relation with FPM was excellent, with UVPM approximately 1 1/2 times FPM. The correlation between UVPM and solanesol was good, but the relationship between the two was not linear. The relation between UVPM and scopoletin was not good, largely because of noise in the scopoletin measures around its limit of detection. We considered the relation between nicotine and saliva cotinine, a metabolite of nicotine. The two were highly correlated on the group level. That is, for each cell (smoking home and work, smoking home but nonsmoking work, and so forth), there was high correlation between average cotinine and 24-hour time-weighted average (TWA) nicotine concentrations. However, on the individual level, the correlations, although significant, were not biologically meaningful. A consideration of cotinine and nicotine or 3-EP on a subset of the study whose only exposure to ETS was exclusively at work or exclusively at home showed that home exposure was a more important source of ETS than work exposure. 相似文献

The grounds for official policy claims that environmental tobacco smoke is a major health risk remain speculative. In scientific terms, the evidence is compatible with either a slight increase or a decrease of risks, but is impotent to certify either conclusion. Official advocacy of unproven hypotheses presented as valid scientific conclusions raises serious ethical questions, and threatens the credibility of risk assessment as a legitimate policy instrument. 相似文献
