Background
Philip Morris (PM) launched the Philip Morris External Research Program (PMERP) in 2000, two years after the company agreed to the dissolution of two industry‐wide, external research programmes: the Council for Tobacco Research (CTR) and the Center for Indoor Air Research (CIAR). Our previous analysis of PMERP''s Request for Applications noted that PMERP''s structure, while ostensibly concerned with new product development, was remarkably similar to that of CIAR. We also found the majority of designated peer‐reviewers had previous ties to the tobacco industry and the research solicitation seemed to invite mitigating evidence concerning cigarettes and constituent risks. We concluded that a prime reason for PMERP''s existence was to garner scientific credibility for PM.Objective
To examine the grants awarded in the first round of PMERP and subsequent peer‐reviewed publications.Methods
Searches of industry documents available on the internet using PMERP and its variations as initial keywords; searches on Medline for publications from PMERP grantees.Results
Of 153 applications, 61 proposals were funded, 36 of which generated 78 scientific publications. Of these, 65% deal specifically with the tobacco plant or constituents. Over half the researchers listed as PMERP participants had previously received or applied for tobacco funding. One internal document indicated PMERP''s objectives included gaining “credibility” and “goodwill”, and finding “young scientists”. In addition, PM has launched its own and more extensive internal product design research programme.Conclusion
PMERP appears to exist less as a conduit for critical scientific inquiry than to fit into a corporate strategy intended to burnish PM''s public image. 相似文献2.
Objective
To examine whether adolescents'' exposure to youth smoking prevention ads sponsored by tobacco companies promotes intentions to smoke, curiosity about smoking, and positive attitudes toward the tobacco industry.Design
A randomised controlled experiment compared adolescents'' responses to five smoking prevention ads sponsored by a tobacco company (Philip Morris or Lorillard), or to five smoking prevention ads sponsored by a non‐profit organisation (the American Legacy Foundation), or to five ads about preventing drunk driving.Setting
A large public high school in California''s central valley.Subjects
A convenience sample of 9th and 10th graders (n = 832) ages 14–17 years.Main outcome measures
Perceptions of ad effectiveness, intention to smoke, and attitudes toward tobacco companies measured immediately after exposure.Results
As predicted, adolescents rated Philip Morris and Lorillard ads less favourably than the other youth smoking prevention ads. Adolescents'' intention to smoke did not differ as a function of ad exposure. However, exposure to Philip Morris and Lorillard ads engendered more favourable attitudes toward tobacco companies.Conclusions
This study demonstrates that industry sponsored anti‐smoking ads do more to promote corporate image than to prevent youth smoking. By cultivating public opinion that is more sympathetic toward tobacco companies, the effect of such advertising is likely to be more harmful than helpful to youth. 相似文献3.

Objective
To describe the nature and timing of, and population exposure to, Philip Morris USA''s three explicit corporate image television advertising campaigns and explore the motivations behind each campaign.Methods
: Analysis of television ratings from the largest 75 media markets in the United States, which measure the reach and frequency of population exposure to advertising; copies of all televised commercials produced by Philip Morris; and tobacco industry documents, which provide insights into the specific goals of each campaign.Findings
Household exposure to the “Working to Make a Difference: the People of Philip Morris” averaged 5.37 ads/month for 27 months from 1999–2001; the “Tobacco Settlement” campaign averaged 10.05 ads/month for three months in 2000; and “PMUSA” averaged 3.11 ads/month for the last six months in 2003. The percentage of advertising exposure that was purchased in news programming in order to reach opinion leaders increased over the three campaigns from 20%, 39% and 60%, respectively. These public relations campaigns were designed to counter negative images, increase brand recognition, and improve the financial viability of the company.Conclusions
Only one early media campaign focused on issues other than tobacco, whereas subsequent campaigns have been specifically concerned with tobacco issues, and more targeted to opinion leaders. The size and timing of the advertising buys appeared to be strategically crafted to maximise advertising exposure for these population subgroups during critical threats to Philip Morris''s public image. 相似文献4.
Levels of toxins in oral tobacco products in the UK 总被引:1,自引:0,他引:1
Objective
This study examined the constituents of smokeless tobacco products available in the UK and compared them with products available in India, Sweden, and the USAMethods
Seven UK brands of smokeless tobacco, including a tooth cleaning powder, and four international brands of smokeless tobacco were tested for a range of toxins and known carcinogens, such as tobacco specific N‐nitrosamines (TSNA), as well as nicotine availability.Results
Ten of the 11 brands tested had detectable levels of tobacco specific nitrosamines, which are proven carcinogens, and levels varied 130‐fold. All had detectable levels of benzo(a)pyrene, another proven carcinogen (with around 175‐fold variation) and several toxic metals (with nearly 150‐fold variation). Nicotine availability varied in the UK products from 0.1 mg/g to 63.2 mg/g. All the tobacco products tested are likely to be hazardous to users'' health, but the data indicate that it should be possible to reduce key toxins to non‐detectable levels.Conclusions
Smokeless tobacco products should be regulated and standards set for maximum levels of toxins and carcinogens. 相似文献5.
Background
Tobacco control in hospital settings is characterised by a focus on protection strategies and an increasing expectation that health practitioners provide cessation support to patients. While practitioners claim to have positive attitudes toward supporting patient cessation efforts, missed opportunities are the practice norm.Objective
To study hospital workplace culture relevant to tobacco use and control as part of a mixed‐methods research project that investigated hospital‐based registered nurses'' integration of cessation interventions.Design
The study was conducted at two hospitals situated in British Columbia, Canada. Data collection included 135 hours of field work including observations of ward activities and designated smoking areas, 85 unstructured conversations with nurses, and the collection of patient‐care documents on 16 adult in‐patient wards.Results
The findings demonstrate that protection strategies (for example, smoking restrictions) were relatively well integrated into organisational culture and practice activities but the same was not true for cessation strategies. An analysis of resources and documentation relevant to tobacco revealed an absence of support for addressing tobacco use and cessation. Nurses framed patients'' tobacco use as a relational issue, a risk to patient safety, and a burden. Furthermore, conversations revealed that nurses tended to possess only a vague awareness of nicotine dependence.Conclusion
Overcoming challenges to extending tobacco control within hospitals could be enhanced by emphasising the value of addressing patients'' tobacco use, raising awareness of nicotine dependence, and improving the availability of resources to address addiction issues. 相似文献6.
Objective
Community members are occasionally polled about tobacco control policies, but are rarely given opportunities to elaborate on their views. We examined laypeople''s conversations to understand how 11 regulatory options were supported or opposed in interactions.Design
Qualitative design; purposive quota sampling; data collection via focus groups.Setting
Three locations in Sydney, Australia.Participants
63 smokers and 75 non‐smokers, men and women, from three age groups (18–24, 35–44, 55–64 years), recruited primarily via telephone.Measurements
Semi‐structured question route; data managed in NVivo; responses compared between groups.Results
Laypeople rejected some regulatory proposals and certain arguments about taxation and the cost of cessation treatments. Protecting children and hypothecating tobacco excise for health education and care were highly acceptable. Plain packaging, banning retail displays and youth smoking prevention received qualified support. Bans on political donations from tobacco corporations were popular in principle but considered logistically fraught. Smokers asked for better cessation assistance and were curious about cigarette ingredients. Justice was an important evaluative principle. Support was often conditional and unresolved arguments frequent. We present both sides of these conflicts and the ways in which policies were legitimised or de‐legitimised in conversation.Conclusions
Simple measures of agreement used in polls may obscure the complexity of community responses to tobacco policy. Support was frequently present but contested; some arguments that seem self‐evident to advocates were not so to participants. The detailed understanding of laypeople''s responses provided through qualitative methods may help frame proposals and arguments to meet concerns about justice, effectiveness and feasibility. 相似文献7.
Objective
To assess the pharmacy profession''s perceptions of tobacco sales in US pharmacies and explore whether a policy prohibiting sales of tobacco in pharmacies would alter adult consumer shopping behaviour.Subjects and design
In California, surveys were administered to 1168 licensed pharmacists and 1518 pharmacy students, and telephone interviews were conducted with 988 adult consumers.Results
Most (58.1%) licensed pharmacists were strongly against sales of tobacco in pharmacies, 23.6% were against it, 16.7% were neutral, 1.2% were in favour of it, and 0.4% were strongly in favour of it. Pharmacists who were current tobacco users were more likely to be in favour of tobacco sales in pharmacies than were pharmacists who were current non‐users (p < 0.005). Similar statistics were observed for pharmacy students. Most consumers (72.3%) disagreed with the statement, “I am in favour of tobacco products being sold in drugstores”; 82.6% stated that if the drugstore where they most commonly shopped were to stop selling tobacco products, they would shop there just as often, 14.2% would shop there more often, and 3.2% would shop there less often.Conclusion
Little professional or public support exists for tobacco sales in pharmacies. 相似文献8.
Objectives
To examine the phenomenon of non‐smokers spontaneously taking action to seek help for smokers; to provide profiles of non‐smoking helpers by language and ethnic groups.Setting
A large, statewide tobacco quitline (California Smokers'' Helpline) in operation since 1992 in California, providing free cessation services in English, Spanish, Mandarin, Cantonese, Korean, and Vietnamese.Subjects
Callers between August 1992 and September 2005 who identified themselves as either white, black, Hispanic, American Indian, or Asian (n = 349 110). A subset of these were “proxies”: callers seeking help for someone else. For more detailed analysis, n = 2143 non‐smoking proxies calling from October 2004 through September 2005.Main outcome measures
Proportions of proxies among all callers in each of seven language/ethnic groups; demographics of proxies; and proxies'' relationships to smokers on whose behalf they called.Results
Over 22 000 non‐smoking proxies called. Proportions differed dramatically across language/ethnic groups, from mean (±95% confidence interval) 2.7 (0.3)% among English‐speaking American Indians through 9.3 (0.3)% among English‐speaking Hispanics to 35.3 (0.7)% among Asian‐speaking Asians. Beyond the differences in proportion, however, remarkable similarities emerged across all groups. Proxies were primarily women (79.2 (1.7)%), living in the same household as the smokers (65.0 (2.1)%), and having either explicit or implicit understandings with the smokers that calling on their behalf was acceptable (90.0 (1.3)%).Conclusions
The willingness of non‐smokers to seek help for smokers holds promise for tobacco cessation and may help address ethnic and language disparities. Non‐smoking women in smokers'' households may be the first group to target. 相似文献9.
Objective
To describe the history of Kool''s music‐themed promotions and analyse the role that music played in the promotion of the brand.Methods
Analysis of previously secret tobacco industry documents, legal documents, and promotional materials.Results
Brown & Williamson started Kool sponsorship of musical events in 1975 with Kool Jazz concerts. Music was considered to be an effective marketing tool because: (1) music helped consumers make emotional connections with the brand; (2) music concerts were effective for targeted marketing; (3) music tied together an integrated marketing campaign; and (4) music had potential to appeal widely to a young audience. Brown & Williamson''s first music campaigns successfully targeted young African‐American male audiences. Subsequent campaigns were less effective, exploring different types of music to achieve a broader young adult appeal.Conclusions
This case study suggests Brown & Williamson used music most successfully for targeted marketing, but they failed to develop a wider audience using music because their attempts lacked consistency with the Kool brand''s established identity. The 2004 “Kool Mixx” campaign both returned to Brown & Williamson''s historic practice targeting young African‐American males, and also exploited a musical genre with much more potential to bring Kool more universal appeal, as hip‐hop music is increasingly popular among diverse audiences. Tobacco control efforts led by African‐American community activists to oppose these marketing strategies should continue; expanding these coalitions to include the hip‐hop community may further increase their effectiveness. 相似文献10.

Objectives
Adverse effects have been reported of prenatal and/or postnatal passive exposure to smoking on children''s health. Uncertainties remain about the relative importance of smoking at different periods in the child''s life. We investigate this in a pooled analysis, on 53 879 children from 12 cross‐sectional studies—components of the PATY study (Pollution And The Young).Methods
Effects were estimated, within each study, of three exposures: mother smoked during pregnancy, parental smoking in the first two years, current parental smoking. Outcomes were: wheeze, asthma, “woken by wheeze”, bronchitis, nocturnal cough, morning cough, “sensitivity to inhaled allergens” and hay fever. Logistic regressions were used, controlling for individual risk factors and study area. Heterogeneity between study‐specific results, and mean effects (allowing for heterogeneity) were estimated using meta‐analytical tools.Results
There was strong evidence linking parental smoking to wheeze, asthma, bronchitis and nocturnal cough, with mean odds ratios all around 1.15, with independent effects of prenatal and postnatal exposures for most associations.Conclusions
Adverse effects of both pre‐ and postnatal parental smoking on children''s respiratory health were confirmed. Asthma was most strongly associated with maternal smoking during pregnancy, but postnatal exposure showed independent associations with a range of other respiratory symptoms. All tobacco smoke exposure has serious consequences for children''s respiratory health and needs to be reduced urgently. 相似文献11.

Objective
To identify the level of effort state tobacco control programmes and partners have expended on interventions recommended by the community guide and how those efforts have changed over time between 1999 and 2004.Design
Longitudinal study.Setting
United States.Participants
State tobacco control partners, including the state health department, voluntary agencies and tobacco control coalitions.Main outcome measure
We used the Strength of Tobacco Control survey responses in 1999, 2002 and 2004 to calculate the mean proportion of state tobacco control partners working on recommended interventions and subsequently analysed changes in effort over time.Results
The proportion of state tobacco control partners working to promote clean indoor air legislation remained at more than 70% in all three years. The proportion working to increase taxes on tobacco rose significantly between 1999 and 2002 (from 54% to 70%), and those working to reduce patient costs for tobacco cessation treatments never exceeded 31% in any year. Use of mass media targeting youths decreased significantly in all years (from 40% to 32% to 26%), and the proportion of state tobacco control partners participating in a quitline has increased steadily and significantly in all years (from 24% to 36% to 41%). The level of effort in each area varied widely between states and over time.Conclusions
State tobacco control partners are implementing evidence based interventions, but more focus is needed on the tobacco cessation and mass media campaign components of comprehensive tobacco control programmes. 相似文献12.
Objective
To understand the implementation and effects of the Courtesy of Choice programme designed to “accommodate” smokers as an alternative to smoke‐free polices developed by Philip Morris International (PMI) and supported by RJ Reynolds (RJR) and British American Tobacco (BAT) since the mid‐1990s in Latin America.Methods
Analysis of internal tobacco industry documents, BAT “social reports”, news reports and tobacco control legislation.Results
Since the mid‐1990s, PMI, BAT and RJR promoted Accommodation Programs to maintain the social acceptability of smoking. As in other parts of the world, multinational tobacco companies partnered with third party allies from the hospitality industry in Latin America. The campaign was extended from the hospitality industry (bars, restaurants and hotels) to other venues such as workplaces and airport lounges. A local public relations agency, as well as a network of engineers and other experts in ventilation systems, was hired to promote the tobacco industry''s programme. The most important outcome of these campaigns in several countries was the prevention of meaningful smoke‐free policies, both in public places and in workplaces.Conclusions
Courtesy of Choice remains an effective public relations campaign to undermine smoke‐free policies in Latin America. The tobacco companies'' accommodation campaign undermines the implementation of measures to protect people from second‐hand smoke called for by the World Health Organization Framework Convention on Tobacco Control, perpetuating the exposure to tobacco smoke in indoor enclosed environments.Latin Americans are highly exposed to second‐hand tobacco smoke (SHS) both in public places and in workplaces.1,2 In 2001, the Pan American Health Organization launched its “Smoke Free Americas” initiative3 to “raise awareness of the harm caused by secondhand tobacco smoke, and support efforts to achieve more smoke‐free environments in the Americas.” There is longstanding strong public concern over the effects of SHS in Latin America. In 1997, research conducted for Philip Morris International (PMI) showed that about 80% of respondents in four Latin American countries agreed that “Other people''s tobacco smoke poses a long term health risk to nonsmokers.”4 These results reflect a stronger consensus that SHS is hazardous than Philip Morris (PM) found in the US in 1989—62% of non‐smokers and 32% of smokers—as the movement for smoke‐free workplaces and public places was beginning to accelerate them.5 A 2001 survey conducted for the World Health Organization (WHO) in the main urban areas of Argentina showed strong public support (94%; 96% non‐smokers and 89% smokers) for the creation of smoke‐free places to avoid SHS.6 Public opinion polls conducted in 2006 in Argentina7 and Uruguay8 reported that 92% of respondents agreed that “SHS is dangerous for nonsmokers'' health”, showing an increase in public concern about SHS by 12% since 1997.The main barrier to progress in implementing smoke‐free policies in Latin America has been the efforts by two transnational tobacco companies, PMI and British American Tobacco (BAT), which control almost the entire cigarette market in the region through their subsidiaries (PMI 40%, BAT 60%). Similar to the voluntary self‐regulating advertising codes, which the tobacco companies use to fight restrictions on tobacco advertising,9,10 the tobacco industry has orchestrated public relations campaigns in Latin America since the mid‐1990s to avoid legislated smoke‐free policies.11,12 As in the US, beginning in the late 1980s,11 this effort mobilised the hospitality industry to block meaningful tobacco control legislation to preserve the social acceptability of smoking and to protect industry profits. These programmes, known as Accommodation in the US and Courtesy of Choice in most parts of the rest of the world,11,13,14,15 encourage the voluntary creation of smoking and non‐smoking sections in the hospitality industry as an alternative to legislation requiring 100% smoke‐free environments. Also, as in the US, the tobacco industry sought to present ventilation as the “solution” to SHS.16As of April 2007, 12 Latin American countries (Bolivia, Brazil, Chile, Ecuador, Guatemala, Honduras, Mexico, Panama, Paraguay, Peru, Uruguay and Venezuela) had ratified the WHO Framework Convention on Tobacco Control (FCTC). The FCTC, the first international public health treaty, calls for the implementation of “effective legislative, executive, administrative or other measures … at the appropriate governmental level to protect all persons from exposure to tobacco smoke” (Article 4.1) “in indoor workplaces, public transport, indoor public places and, as appropriate, other public places.” (Article 8).17 Given the fact that the only truly effective protection from SHS is the creation of 100% smoke‐free environments,18 in 2003, Venezuela approved a state law (in Monagas19) and between 2005 and 2006, Argentina passed and regulated two provincial laws (in Santa Fe and Tucumán) to establish 100% smoke‐free public places and workplaces. In March 2006, Uruguay became the first 100% smoke‐free country in the Americas. In response to this movement, one can expect the tobacco industry to accelerate its Accommodation efforts as a way of undermining such effective smoke‐free policies to implement FCTC. 相似文献13.
Objectives
To assess the magnitude of cigarette smuggling after the market opened in Taiwan.Methods
Review of tobacco industry documents for references to smuggling activities related to Taiwan and government statistics on seizure of smuggled cigarettes.Results
The market opening in 1987 led to an increase in smuggling. Contraband cigarettes became as available as legal ones, with only a small fraction (8%) being seized. Being specifically excluded from the market‐opening, Japan entered the Taiwan market by setting up a Swiss plant as a legal cover for smuggling 10–20 times its legal quota of exports to Taiwan. Smuggling in Taiwan contributed to increased consumption of foreign brands, particularly by the young. Taiwan, not a member of the World Health Organization, was excluded from the East Asian 16‐member “Project Crocodile”, a regional anti‐smuggling collaborative effort to implement the Framework Convention on Tobacco Control.Conclusions
Taiwan showed a sharp increase in smuggling after market liberalisation. Being excluded from the international community, Taiwan faces an uphill battle to fight smuggling alone. If Taiwan remained as its weakest link, global efforts to reduce tobacco use will be undermined, particularly for countries in the East Asian region. 相似文献14.

This paper analyses Philip Morris''s evolving website and the legal strategies employed in its creation and dissemination.Methods
Internal tobacco documents were searched and examined and their substance verified and triangulated using media accounts, legal and public health research papers, and visits to Philip Morris''s website. Various drafts of website language, as well as informal discussion of the website''s creation, were located in internal Philip Morris documents. I compared website statements pertaining to Philip Morris''s stance on cigarette smoking and disease with statements made in tobacco trials.Results
Philip Morris created and disseminated its website''s message that it agreed that smoking causes disease and is addictive in an effort to sway public opinion, while maintaining in a litigation setting its former position that it cannot be proved that smoking causes disease or is addictive.Conclusions
Philip Morris has not changed its position on smoking and health or addiction in the one arena where it has the most to lose—in the courtroom, under oath. 相似文献15.
Objective
To examine the tactics the tobacco industry in Germany used to avoid regulation of secondhand smoke exposure and to maintain the acceptance of public smoking.Methods
Systematic search of tobacco industry documents available on the internet between June 2003 and August 2004.Results
In West Germany, policymakers were, as early as the mid 1970s, well aware of the fact that secondhand smoke endangers non‐smokers. One might have assumed that Germany, an international leader in environmental protection, would have led in protecting her citizens against secondhand smoke pollution. The tobacco manufacturers in Germany, however, represented by the national manufacturing organisation “Verband” (Verband der Cigarettenindustrie), contained and neutralised the early debate about the danger of secondhand smoke. This success was achieved by carefully planned collaboration with selected scientists, health professionals and policymakers, along with a sophisticated public relations programme.Conclusions
The strategies of the tobacco industry have been largely successful in inhibiting the regulation of secondhand smoke in Germany. Policymakers, health professionals, the media and the general public should be aware of this industry involvement and should take appropriate steps to close the gap between what is known and what is done about the health effects of secondhand smoke. 相似文献16.
Background
The US military is perhaps the only retailer consistently losing money on tobacco. Military stores (commissaries and exchanges) have long sold discount‐priced cigarettes, while the Department of Defense (DoD) pays directly for tobacco‐related healthcare costs of many current and former customers. Tobacco use also impairs short‐term troop readiness.Objective
To examine the long struggle to raise commissary tobacco prices and the tobacco industry''s role in this policy effort.Methods
Analysis of internal tobacco industry documents, searches of government and military websites and newspaper databases, and interviews with key informants identified in the documents.Results
Efforts to raise commissary tobacco prices began in the mid‐1980s. Opposition quickly emerged. Some military officials viewed tobacco use as a “right” and low prices as a “benefit”. Others raised issues of authority, and some saw the change as threatening the stores. The tobacco industry successfully exploited complex relationships among the Congress, the DoD, commissaries, exchanges and private industry, obstructing change for over a decade. Leadership from the Secretary and Assistant Secretaries of Defense, presidential support and procedural manoeuvring finally resulted in a modest price increase in 1996, but even then, high‐level military officials were apparently threatened with retaliation from pro‐tobacco Congressmen.Conclusions
The longstanding military tradition of cheap cigarettes persists because of the politics of the military sales system, the perception within the military of tobacco use as a right, and tobacco industry pressures. Against its own best interests, the US military still makes tobacco available to service members at prices below those in the civilian sector.The US military includes 1.4 million active duty personnel, stationed worldwide. Their smoking prevalence is higher (33.8% in 2002) than the US Department of Defense (DoD) goal of ⩽20%,1 exceeding the civilian rate of 23.6%.2 Smoking diminishes even short‐term troop health and readiness3,4 and increases medical and training costs.5,6 As an authoritarian, hierarchical institution, DoD should, theoretically, be able to establish and implement strong tobacco control policies. Nonetheless, DoD sells its personnel tobacco products virtually tax free. Military health personnel and some members of Congress have long sought to address this contradiction. This case study shows how for more than a decade, the tobacco industry worked to defeat policy changes by framing cheap cigarettes as a “benefit”, mobilising Congressional and military‐affiliated allies, and exploiting DoD ambivalence about tobacco. 相似文献17.
Objective
To characterise the relative amount and type of daily newspaper, local and national TV newscast, and national news magazine coverage of tobacco control issues in the United States in 2002 and 2003.Design
Content analysis of daily newspapers, news magazines, and TV newscasts.Subjects
Items about tobacco in daily newspapers, local and national TV newscasts, and three national news magazines in a nationally representative sample of 56 days of news stratified by day of week and season of the year, from 2002 and 2003.Main outcome measures
Story theme, tobacco topics, sources, story prominence, story valence (orientation), and story type.Results
Tobacco coverage was modest over the two‐year period as estimated in our sample. Only 21 TV stories, 17 news magazine stories, and 335 daily newspaper stories were found during the two‐year sampling period. Noteworthy results for the newspaper data set include the following: (1) government topics predominated coverage; (2) government action and negative health effects topics tended not to occur together in stories; (3) tobacco stories were fairly prominently placed in newspapers; (4) opinion news items tended to favour tobacco control policies, while news and feature stories were evenly split between positive and negative stories; and (5) tobacco coverage in the southeast, which is the country''s major tobacco producing region, did not differ from the rest of the country.Conclusion
Results suggest mixed support in news coverage for tobacco control efforts in the United States. The modest amount of news coverage of tobacco is troubling, particularly because so few news stories were found on TV, which is a more important news source for Americans than newspapers. When tobacco was covered, government themed stories, which often did not include mentions of negative health effects, were typical, suggesting that media coverage does not reinforce the reason for tobacco control efforts. However, some results were encouraging. For example, when newspapers did cover tobacco, they accorded the stories relatively high prominence, thus increasing the chance that readers would see tobacco stories when they were published. 相似文献18.
Objective
To describe the development and health claims of Asian herbal‐tobacco cigarettes.Methods
Analysis of international news sources, company websites, and the transnational tobacco companies'' (TTC) documents. PubMed searches of herbs and brands.Results
Twenty‐three brands were identified, mainly from China. Many products claimed to relieve respiratory symptoms and reduce toxins, with four herb‐only products advertised for smoking cessation. No literature was found to verify the health claims, except one Korean trial of an herb‐only product. Asian herbal‐tobacco cigarettes were initially produced by China by the 1970s and introduced to Japan in the 1980s. Despite initial news about research demonstrating a safer cigarette, the TTC analyses of these cigarettes suggest that these early products were not palatable and had potentially toxic cardiovascular effects. By the late 1990s, China began producing more herbal‐tobacco cigarettes in a renewed effort to reduce harmful constituents in cigarettes. After 2000, tobacco companies from Korea, Taiwan, and Thailand began producing similar products. Tobacco control groups in Japan, Taiwan, and Thailand voiced concern over the health claims of herbal‐tobacco products. In 2005, China designated two herbal‐tobacco brands as key for development.Conclusion
Asian herbal‐tobacco cigarettes claim to reduce harm, but no published literature is available to verify these claims or investigate unidentified toxicities. The increase in Asian herbal‐tobacco cigarette production by 2000 coincides with the Asian tobacco companies'' regular scientific meetings with TTCs and their interest in harm reduction. Asia faces additional challenges in tobacco control with these culturally concordant products that may discourage smokers from quitting. 相似文献19.
Objectives
To determine the effects of aging on the toxicity of sidestream tobacco smoke, the complex chemical mixture that enters the air from the lit end of burning cigarettes and constitutes the vast bulk of secondhand smoke.Design
Statistical analysis of data from controlled experimental exposures of Sprague Dawley rats to fresh and aged (for more than 30 minutes) sidestream smoke for up to 90 days followed by histological sectioning of the respiratory epithelium. The data were obtained from a series of experiments conducted at Philip Morris'' formerly secret INBIFO (Institut für Biologische Forschung) laboratory in Germany.Results
Using total particulate material as the measure of smoke exposure, aging sidestream cigarette smoke for at least 30 minutes increases its toxicity fourfold for 21 day exposures and doubles the toxicity for 90 day exposures, relative to fresh sidestream smoke.Conclusions
These results help explain the relatively large biological effects of secondhand smoke compared to equivalent mass doses of mainstream smoke. 相似文献20.
