Legislative provisions for standardised tobacco packaging and changes in public support in 27 European countries

BackgroundGlobal adoption of standardised packaging requirements for tobacco products is a victory for public health, but their proliferation and impacts rely partly on public support. How this is related to legislation remains underassessed. This study explored change over time in public support for standardised packaging in countries with varying degrees of legislative provisions.MethodsWe used data from 27 European countries, collected from 2017 (n=28, 300) and 2020 (n=27, 901) waves of the Eurobarometer survey, to assess self-reported support for standardised packaging regulations among both smokers and non-smokers. Countries were grouped into three categories of policy adoption (policy implemented; policy legislated; no legislation) and changes in support were assessed using multilevel Poisson regression models.ResultsIn 2020, public support for standardised packaging was 71% (95% CI 68% to 74%) in countries that implemented standardised packaging legislation, 57% (55% to 60%) in countries that had legislated but not yet implemented legislation and 41% (40%to 42%) in countries with no legislation. Compared with 2017, this represented a relative change of +8% (1% to 15%), +12% (5% to 21%) and −5% (95% CI −2% to −8%), respectively, in the three country categories. Among smokers, there was no indication of change in support across the three groups. Among non-smokers, support increased in countries with existing legislation (adjusted prevalence ratio [aPR]=1.14, 95% CI 1.06 to 1.23) and decreased in countries with no legislation (aPR=0.93, 0.90 to 0.97).ConclusionsPublic support for standardised packaging regulations increased in countries implementing and legislating for these measures, particularly among non-smokers. An overall increase in support provides reassurance for policymakers defending policy action on tobacco packaging, as well as for those seeking to implement standardised packaging in their own countries.

Monitoring compliance with Senegal’s tobacco products packaging and labelling requirements 6 months after implementation of the law

IntroductionAs of December 2021, 22 countries and one jurisdiction in WHO African Region (AFRO) have adopted pictorial health warning labels on tobacco packaging, but only 13 have implemented them. In 2014, Senegal enacted a comprehensive tobacco control law, which requires strong provisions on tobacco packaging and labelling. The objective of this study was to assess the level of compliance with these provisions in Senegal 6 months after implementation.MethodsData collection took place in Senegal’s capital city of Dakar across 12 districts in February 2018, following the Tobacco Pack Surveillance System Field Protocol developed by the Institute for Global Tobacco Control at Johns Hopkins Bloomberg School of Public Health. Unique tobacco packs were purchased from a total of 48 tobacco vendors, and compliance with new packaging and labelling provisions was assessed.ResultsIn total, seven unique cigarette packs were confirmed to be legally available for sale in Dakar, Senegal. All packs complied with all health warning provisions (type, size, location, language and quitline information) as well as bans on quantitative emissions yields. However, no pack complied with the descriptive constituents and emissions statement required on the lateral side, and four of the seven packs violated the ban on misleading brand descriptors.ConclusionsAFRO countries have made substantial progress in adopting comprehensive tobacco control laws that bring them closer into alignment with the Framework Convention on Tobacco Control. This study found areas of effective implementation of FCTC recommended packaging and labelling requirements, as well as areas in need of stronger enforcement.

Relationship between internet research data of oral neoplasms and public health programs in the European Union

Background Tobacco and alcohol are the main risk factors for oral squamous cell carcinoma, the low survival rate of which is a public health problem. European-wide health policies (a prevention campaign, tobacco packaging) have been put in place to inform the population of the risks associated with consumption. Due to the increase in smoking among women, the incidence of this disease remains high. The identification of internet research data on the population could help to measure the impact of and better position these preventive measures. The objective was to analyze a potential temporal association between public health programs and interest in oral cancers on the internet in the European Union (EU). Methods A search of data from Google ©, Wikipedia © and Twitter © users in 28 European countries relating to oral cancer between 2004 and 2019 was completed. Bibliometric analysis of press and scientific articles over the same period was also performed. The association between these data and the introduction of public health programs in Europe was studied. Results There was a temporal association between changes in tobacco packaging and a significant increase in internet searches for oral cancer in seven countries. Unlike national policies and ad campaigns, the European awareness program Make Sense has had no influence on internet research. There was an asymmetric correlation in internet searches between publications on oral cancer from scientific articles or "traditional" media (weak association) and those from internet media such as Twitter © or Wikipedia © (strong association). Conclusion Our work highlights seven areas around which oral cancer awareness in Europe could be refocused, such as a change in the communication of health warnings on cigarette packs, the establishment of a more explicit campaign name regarding oral cancer, the involvement of public figures and associations in initiatives to be organized at the local level and the strengthening of awareness of the dangers of tobacco in the development of oral cancer.

Was the implementation of standardised tobacco packaging legislation in England associated with changes in smoking prevalence? A segmented regression analysis between 2006 and 2019

Background and aimIn 2016, England initiated the implementation of standardised tobacco packaging, introduced in conjunction with minimum pack sizes and other measures included in the 2014 European Tobacco Products Directive, over the course of a 1-year sell-off period ending in May 2017. These measures have been shown to have been associated with increases in tobacco prices and product diversity. We now investigate the association between implementation of the new legislation and smoking status in England.DesignSegmented regression analysis of repeated cross-sectional surveys using a generalised linear model with individual-level data to test for a change in trend and immediate step change.SettingEngland.ParticipantsParticipants in the Smoking Toolkit Study, which involves repeated, cross‐sectional household surveys of individuals aged 16 years and older in England. The sample included 278 219 individual observations collected between November 2006 and December 2019.InterventionImplementation of standardised packaging legislation (May 2016 and May 2017).MeasurementsIndividual-level current smoking status adjusted for implementation of tobacco control policies, cigarette price, seasonality and autocorrelation.FindingsThe implementation of standardised packaging was associated with a significant step reduction in the odds of being a smoker after May 2017 (OR: 0.93; 95% CI 0.87 to 0.99). The magnitude of the association was similar when modelling the step change in May 2016 at the start of the 1-year policy implementation period (OR: 0.90; 95% CI: 0.83 to 0.97).ConclusionsThis is the first independent study demonstrating that implementation of standardised packaging was associated with a reduction in smoking in England which occurred in anticipation of, rather than after, full policy implementation. It appears that the odds of being a smoker were affected by the prospect of the move to standardised packs and accompanying legislation.

Tendency of Internet Search Data of Oral Neoplasms and Impact of Public Health Programs in European Union

Background: Tobacco and alcohol are the main risk factors for oral squamous cell carcinoma, the low survival rate of which is a public health problem. European-wide health policies (prevention campaign, tobacco packaging) have been put in place to inform the population of the risks associated with their consumption. Due to the increase in smoking among women and changes in sexual practices, the incidence of this disease is still too high. The identification of data from internet research on the population could make it possible to measure the impact and better orient these preventive measures.The objective was to analyse the data on interest shown in oral cancers from several online databases, and to cross-reference them with the data on the introduction of European public health programs.Methods: A search of data from Google ©, Wikipedia © and Twitter © users in 28 European countries relating to oral cancer between 2004 and 2019 was carried out. Bibliometric analysis of press and scientific articles over the same period was also analysed. The association between these data and the introduction of public health programs in Europe has been studied.Results: Changes in tobacco packaging correlated with a significant increase in internet research on oral cancer in 7 countries. Unlike national policies and campaigns, the European awareness program Make Sense has had no influence on internet research. There was an asymmetric correlation in internet searches between publications on oral cancer from scientific articles or "traditional" media (weak association) and those from internet media such as Twitter © or Wikipedia © (strong association).Conclusion: Our work highlights 7 areas of work around which oral cancer awareness in Europe could be refocused.

Visual detection of tobacco packaging film based on apparent features

The main purpose of this article is to study the detection of transparent film on the surface of tobacco packs. Tobacco production line needs an industrial robot to remove the transparent film in the process of unpacking. Therefore, after the industrial robot removes the transparent film, it is necessary to use machine vision technology to determine whether there is transparent film residue on the surface of tobacco packaging. In this article, based on the study of the optical features of semitransparent objects, an algorithm for detecting the residue of transparent film in tobacco packs based on surface features is proposed. According to the difference of surface features between tobacco and film, a probability distribution model considering highlights, saturation, and texture density is designed. Because the probability distribution model integrates many features of tobacco and film, it is more reasonable to distinguish the tobacco film regions. In this article, an appropriate foreground box with a trapezoidal mask and image segmentation algorithm GrabCut is used to segment the foreground area of tobacco pack more accurately, and the possible film area is obtained by image differential and morphological processing. Finally, on the basis of comparing the effect of various machine learning algorithms on the image classification of possible film regions, support vector machine based on color features is used to judge the possible film region. Application results of the system show that the method proposed in this article can effectively detect whether there is film residue on the surface of tobacco pack.
