Tobacco packaging littering behaviours among Australian adults who smoke: findings from cross-sectional and observational studies to inform the implementation of cigarette pack inserts.

BACKGROUND: Cigarette pack inserts are small cards that highlight the benefits of quitting and promote use of smoking cessation support. With evidence from Canada that they increase self-efficacy to quit, quit attempts and sustained cessation, inserts are set to be introduced into tobacco packs sold in Australia. Some people have expressed concern that the introduction of inserts may create more litter if incorrectly disposed of on pack-opening. METHODS: We used a cross-sectional survey to assess self-reported pack-opening location and waste disposal behaviours of people who smoke to determine the potential for littering to occur when tobacco packs are first opened. We also visited a sample of supermarkets, convenience stores and tobacconists located throughout Melbourne, Australia, to discreetly collect observational data regarding pack-opening and waste disposal behaviours at the point of purchase. RESULTS: Among participants in the cross-sectional study (N=369), the majority reported that they opened their most recent tobacco pack at home (70.9%) where there is little potential for littering, and this proportion was higher among those who smoke daily (78.6%) and men (74.3%). Self-reported behaviours that could result in littering were rare; 1.0% reported that they left tobacco packaging where they believed it would be collected for disposal. Of the 128 individuals observed at the point of purchase across 46 stores, 96.9% did not open the tobacco product immediately after purchase. One incident of littering was observed (0.8%). CONCLUSION: The introduction of cigarette pack inserts in Australia is unlikely to create a substantial amount of additional litter.

Evaluation of the effectiveness of the Indian government's policies to strengthen health warning labels on smokeless tobacco products: findings from the 2010-2019 Tobacco Control Project India Surveys.

BACKGROUND: Smokeless tobacco (SLT) packaging in India had a single symbolic (a scorpion) health warning label (HWL) in 2009 covering 40% of the front surface. In 2011, it was replaced with four pictorial images. In 2016, HWLs were enlarged to 85% on the front and back. This study aimed to assess the effectiveness of the old (symbolic and smaller images) and larger HWLs. METHODS: Data were from the Tobacco Control Project India Survey and included respondents who used SLT in Wave 1 (2010-2011, n=5911), Wave 2 (2012-2013, n=5613) and Wave 3 (2018-2019, n=5636). Using a repeated-measures design, weighted logistic regression models assessed whether there were changes in seven HWL effectiveness measures within the domains of awareness, salience, cognitive and behavioural responses. A cohort design was employed to test whether HWL effectiveness in Waves 1 and 2 was associated with quitting SLT in Waves 2 and 3, respectively. RESULTS: The 2011 HWL revision did not result in any significant changes in HWL effectiveness. There was no significant change in HWL awareness and salience after larger HWLs were introduced in 2016, but respondents were more likely to consider SLT health risks (Wave 2=17.9%, Wave 3=33.6%, p<0.001) and quitting SLT (Wave 2=18.9%, Wave 3=36.5, p<0.001). There was no change in HWLs stopping SLT use (Wave 2=36.6%, Wave 3=35.2%, p=0.829); however, respondents were more likely to avoid looking at HWLs (Wave 2=10.1%, Wave 3=40.2%, p<0.001). Effectiveness of older, symbolic and smaller pictorial HWLs was not associated with quitting SLT. DISCUSSION: There was no significant change in HWL effectiveness following the revision from a symbolic to a pictorial image, but enlarging pictorial images resulted in some improved cognitive and behavioural effects. Results suggested wear-out of HWL salience and that the effectiveness of warnings depends on both their design and time since implementation.

Nicotine beliefs and perceptions of low nicotine labels and mitigating statements among people who do and do not smoke: a cross-sectional study from Aotearoa New Zealand.

BACKGROUND: Aotearoa New Zealand proposed a new maximum nicotine content of 0.8 mg/g for smoked tobacco products, although the new government plans to repeal this legislation. Requiring 'Very low nicotine' (VLN) messages on cigarettes meeting this standard may reinforce misperceptions that they are less harmful than cigarettes currently sold. METHODS: To explore knowledge of nicotine and very low nicotine cigarettes (VLNCs), and perceptions of cigarette packs featuring different low nicotine messages (eg, 'Very low nicotine') and mitigating statements (eg, 'No cigarettes are safe'), we surveyed 354 people who smoked, 142 who formerly smoked, and 214 people who had never smoked regularly. RESULTS: Around half of all respondents believed VLNCs were less harmful than regular cigarettes and around two-thirds incorrectly thought nicotine causes most of the related health problems resulting from smoking. Nearly a third thought VLNCs would be less harmful than regular cigarettes; 34% believed they would be just as harmful. Mitigating statements did not affect perceptions of people who smoked, although people who formerly, or who had never smoked regularly, perceived mitigating statements referring to poisons and cancer as significantly more likely than the VLN message to discourage smoking. CONCLUSIONS: Misunderstanding of VLNCs as less harmful than regular cigarettes is widespread; VLN messages may reinforce this misperception, which mitigating statements did not correct among people who smoke. As an alternative to VLN messages, policy makers could consider introducing VLNCs on a specified date and developing public information campaigns; these measures would avoid phase-in confusion and obviate the need for VLN messaging.

Association between the implementation of standardised tobacco packaging legislation and illicit tobacco and cross-border purchasing in England: a time-series analysis between 2012 and 2020.

BACKGROUND: In May 2016, the UK announced standardising packaging legislation for tobacco products. There was a 12-month transition period with both branded and standardised packs on the market until May 2017. The aim of this study was to investigate whether the implementation of standardised packaging in England was associated with changes in illicit tobacco and cross-border purchasing. METHODS: We used Smoking Toolkit Study data covering the time period from 2012 to 2020. We ran time-series analysis using Autoregressive Integrated Moving Average with Exogenous Variable models to investigate the monthly changes in illicit tobacco and cross-border purchasing in England. The model was adjusted for other tobacco control policies implemented during the relevant time period and tobacco pricing. We used May 2017 as an implementation point and run sensitivity analysis using July 2016 and February 2017 as alternative implementation points given phased introduction of the policy. RESULTS: The average prevalence of illicit tobacco and cross-border purchasing in the past 6 months was 14.4%. The implementation of standardised tobacco packaging legislation was associated with a monthly decline in illicit tobacco and cross-border purchases after May 2017 by 0.16% per month (beta=-0.158, 95% CI -0.270 to -0.046). The results were robust to considering different implementation points for the policy (July 2016: beta=-0.109, 95% CI -0.213 to -0.005; February 2017: beta=-0.141, 95% CI -0.245 to -0.036). CONCLUSIONS: In contrast to the tobacco industry's argument that the legislation would lead to an increase in the illicit tobacco and cross-border market, this study demonstrates that the implementation of the policy is associated with a decline in illicit tobacco and cross-border purchases in England.

Building consensus on a set of ENDS-specific pictorial health warnings: a Delphi study among a tobacco control expert panel.

BACKGROUND: This study reports on the development of pictorial health warning labels for electronic nicotine delivery system (ENDS) using the Delphi approach with a panel of tobacco control experts. Twenty-four evidence-based ENDS-specific warnings corresponding to three themes (toxicity, health risks and specific harm) were developed and used in the Delphi study. METHODS: We conducted a three-round online Delphi study among 60 experts (55% female) between June 2022 and April 2023. We balanced the panel in areas of expertise and positions relevant to ENDS (risks, benefits). In round 1, participants rated the warnings on attention, relevance to evidence and perceived effectiveness (harm perception, motivation to quit) and provided suggestions for improvement. In rounds 2 and 3, participants ranked the revised warnings based on importance in each theme. We assessed levels of agreement between participants using interquartile deviations and medians. RESULTS: Warnings in theme 1, toxicity, received the highest ratings for perceived effectiveness on harm perception and encouraging quitting ENDS (p<0.05). Experts recommended using clear and affirmative text paired with emotion-provoking pictures and avoiding the rare side effects of ENDS. Most of the top-ranked warnings were from theme 3, ENDS-specific harm, pertained to lung damage, dual use of ENDS and cigarettes, nicotine addiction among youth, anti-ENDS industry sentiment and toxicity. DISCUSSION: This study developed 24 evidence-based ENDS health warning labels using a systematic process that included several rounds of expert panel feedback. These warnings can be used to advance ENDS prevention and tobacco control policies and further target different populations.

Levels of nicotine and tobacco-specific nitrosamines in oral nicotine pouches.

BACKGROUND: Nicotine pouches without tobacco are new products that deliver nicotine into the body via the oral mucosa. There is a lack of independent research on the chemical composition and product characteristics of these products, contributing to uncertainties regarding product regulation. This study sought to address knowledge gaps by assessing levels of nicotine and screening for tobacco-specific nitrosamines (TSNAs) in a sample of these products. METHODS: Nicotine pouches (n=44) and nicotine-free pouches (n=2) from 20 different manufacturers were analysed regarding their contents of nicotine and TSNAs by gas chromatography with flame ionisation and liquid chromatography-tandem mass spectrometry, respectively. Product labelling and pH values of aqueous extracts were determined. RESULTS: Nicotine contents of products ranged from 1.79 to 47.5 mg/pouch; median product weight, pH, and proportion of free-base nicotine were 0.643 g, 8.8, and 86%, respectively. A clear labelling of the nicotine content was missing on 29 products and nicotine strength descriptions were ambiguous. TSNAs were detected in 26 products, with a maximum of 13 ng N-nitrosonornicotine/pouch. CONCLUSION: Although nicotine pouches may potentially be a reduced risk alternative for cigarette smokers or users of some other oral tobacco products, nicotine contents of some pouches were alarmingly high. Presence of carcinogenic TSNAs in the nicotine pouches is of serious concern. Better manufacturing processes and quality control standards should be implemented. Labels of nicotine strength on most products are misleading. A strict regulation regarding nicotine contents and its labelling would be advisable.

Tobacco industry interference to undermine the development and implementation of graphic health warnings in Bangladesh.

BACKGROUND: In Bangladesh, the 2013 Amendment of the Tobacco Control Act made graphic health warnings (GHWs) on the upper 50% of all tobacco packs obligatory. However, at the time of writing (May 2022), GHWs are still being printed on the lower 50% of packs. This paper seeks to explore how the tobacco industry undermined the development and implementation of GHWs in Bangladesh, a country known for a high level of tobacco industry interference (TII) that has rarely been examined in the peer-reviewed literature. METHODS: Analysis of print and electronic media articles and documents. RESULTS: Cigarette companies actively opposed GHWs, while bidi companies did not. The primary strategy used to influence the formulation and delay the implementation of GHWs was direct lobbying by the Bangladesh Cigarette Manufacturers' Association and British American Tobacco Bangladesh. Their arguments stressed the economic benefits of tobacco to Bangladesh and sought to create confusion about the impact of GHWs, for example, claiming that GHWs would obscure tax banderols, thus threatening revenue collection. They also claimed technical barriers to implementation-that new machinery would be needed-leading to delays. Tensions between government bodies were identified, one of which (National Board of Revenue)-seemingly close to cigarette companies and representing their arguments-sought to influence others to adopt industry-preferred positions. Finally, although tobacco control advocates were partially successful in counteracting TII, one self-proclaimed tobacco control group, whose nature remains unclear, threatened the otherwise united approach. CONCLUSIONS: The strategies cigarette companies used closely resemble key techniques from the well-evidenced tobacco industry playbook. The study underlines the importance of continuing monitoring and investigations into industry conduct and suspicious actors. Prioritising the implementation of WHO Framework Convention on Tobacco Control Article 5.3 is crucial for advancing tobacco control, particularly in places like Bangladesh, where close government-industry links exist.

Cigarette unit sales volume for brands using 'natural', 'organic' and 'tobacco and water' pack terms in the USA, 2018-2022.

BACKGROUND: Terms such as 'natural', 'organic' and 'tobacco and water' on cigarette packs may communicate misleading reduced harm messages to consumers. This study describes sales volume and price for brands that used these misleading descriptors in the USA by year, brand and state. METHODS: The data come from Information Resources Incorporated sales data collected in 44 US states from January 2018 to January 2023. Trained coders used Universal Product Codes, purchased packs and internet searches to identify cigarettes sold with 'natural', 'organic' and 'tobacco and water' on packs. We report cigarette pack unit sales counts (sales volume) and average price per pack by year, as well as per cent year-over-year change in sales volume and price and annual market share by descriptor terms. RESULTS: Overall, pack sales volume decreased year-over-year from 2019 to 2022. Sales volume for packs with 'natural', 'tobacco and water' and 'organic' decreased less than overall; in some cases, they increased. In 2022, packs with 'natural' accounted for the greatest share of cigarette unit sales (5.42% or 33 605 036 packs), followed by 'tobacco and water' (2.25% or 12 959 905 packs) and 'organic' (0.53% or 4 614 592 packs). Natural American Spirit (NAS) and Winston accounted for most sales with 'natural' and 'tobacco and water'; NAS accounted for nearly all sales with 'organic'. Packs with 'natural', 'tobacco and water' or 'organic' made up the largest portion of sales in western (Oregon, Idaho, California, Colorado and Washington) and northeastern (Vermont, Massachusetts and New Hampshire) US states. CONCLUSION: Brands using 'natural', 'tobacco and water' and 'organic' on packs increased their market share between 2019 and 2022; in some states, market share was over 10% in 2022. Our findings emphasise the importance of regulating these terms and continually monitoring their population impact.

Impact of product-based e-cigarette marketing on the attitudes and behavioural intentions of young Australians: an experimental study.

BACKGROUND: The tobacco industry has a history of using language to downplay the harms associated with cigarettes and mislead consumers and policymakers. Emerging evidence suggests similar tactics are being used in the context of e-cigarettes; however, exploration of the impact of product name on attitudes towards e-cigarettes and susceptibility to use is lacking. This experimental study explored whether attitudes towards e-cigarettes and susceptibility to use are influenced by the names used by the industry to describe and market these products. METHOD: An accredited web panel provider recruited a sample of 383 Australians aged 12-29 years who had never smoked to participate in an online survey that featured an embedded experiment. Participants were randomly allocated to one of three conditions, each of which used a different name to describe e-cigarettes (condition 1: 'e-cigarettes', condition 2: 'vapes'; condition 3: either 'IGETS', 'Puff Bars', 'HQD Cuvies' or 'Gunnpods'). The survey assessed respondents' overall opinion of the product described; attitudes towards the product; liking of the product; and curiosity, willingness and intentions to use the product. RESULTS: Those in the 'brand name' condition scored higher than those in the 'e-cigarettes' condition on all dependent variables. Those in the 'vapes' condition scored higher than those in the 'e-cigarettes' condition on product attitude. CONCLUSION: Findings indicate that the use of brand names and terms such as 'vapes' instead of 'e-cigarettes' results in more favourable attitudes towards e-cigarettes and susceptibility to use among young Australians. Results highlight the problematic influence of promotional language use favoured by industry.

Rotation of tobacco health warnings and messages: challenges and recommendations for implementation.

Health warnings and messages-or health warning labels (HWLs)-are integral to tobacco control efforts, but their sustained impact necessitates regular rotation. This paper explores challenges in HWL rotation implementation across six diverse countries: Chile, Guyana, Indonesia, Jamaica, Mexico, and Vietnam. 19 in-depth interviews were conducted with government officials and representatives from civil society organisations and academia. Interviews explored the effectiveness of HWL regulations, the processes involved in their execution, and any challenges encountered along the way. Interviews were analysed thematically, using a combination of deductive and inductive approaches. Interviews revealed critical challenges that fall into two categories: specific and overarching. Government priorities and transitions, political will, time and bureaucracy, legal loopholes, lack of images, evaluation, and economic and human resources constitute HWL-specific challenges. Broad tobacco control challenges included tobacco industry interference and enforcement difficulties. To address HWL rotation challenges, international bodies such as WHO could establish extensive image banks, pre-evaluated for effectiveness and cultural relevance. In addition, countries must institutionalise the rotation process by establishing mechanisms that avoid having to pass complex legal instruments with each new round of warnings, delegating responsibilities to stable government institutions, addressing legal loopholesand planning for multiple rounds within a single legal instrument. Further, partnerships at national and international levels, along with systematic evaluations, are crucial for successful HWL implementation. These recommendations form a comprehensive framework for global collaboration, aiming to strengthen tobacco prevention through impactful HWLs on a sustainable basis.

Impact of Standardised Packaging of Tobacco Products Regulations on cigarette consumption and youth smoking in England: interrupted time-series analysis.

BACKGROUND: In the UK in May 2016, standardised packaging of tobacco products was implemented, including minimum pack sizes of 20 sticks or 30 g loose tobacco. The change was intended to reduce uptake by increasing upfront costs to young people, but there was concern it may unintentionally increase consumption among people smoking. This study aimed to assess whether the introduction of the policy was associated with changes in (1) mean daily factory-made (FM)/roll-your-own (RYO) cigarettes consumption among people smoking predominantly (a) FM and (b) RYO cigarettes; and (2) current smoking prevalence among 16-24-year-olds. METHODS: Data (N=257 929) were from a representative monthly cross-sectional survey of adults (≥16 years) in England, collected between November 2007 and January 2020. Outcome measures were mean daily (FM/RYO) cigarette consumption among those smoking FM/RYO cigarettes, and prevalence of current smoking among 16-24-year-olds. Time-series analyses were conducted using Autoregressive Integrated Moving Average with Exogenous variables (ARIMAX) regression models including a gradual level change starting in June 2017 and ending in May 2018 for cigarette consumption and a step change in June 2016 for prevalence of current smoking. RESULTS: The ARIMAX model was not able to detect a change in mean daily cigarette consumption-for FM (Badj=-0.543, 95% CI -1.381 to 0.296) or RYO (Badj=0.002, 95% CI -0.518 to 0.522) following the implementation of standardised packaging. The unadjusted analysis suggested the implementation of standardised packaging was associated with a small (3%) decrease in smoking prevalence among 16-24-year-olds (Bunadj=-0.031, 95% CI -0.062 to 0.000), but this association was attenuated after adjustment for covariates (Badj=-0.010, 95% CI -0.039 to 0.019). CONCLUSIONS: The implementation of standardised packaging of tobacco products was not associated with a meaningful change in the mean number of FM or RYO cigarettes consumed by people smoking in England, suggesting the larger pack size has not had an unintended consequence of substantially increasing cigarette consumption. However, there was also little evidence that the policy substantially reduced smoking among 16-24-year-olds.

Tobacco product litter as a form of postconsumption marketing: an observational study in India.

BACKGROUND: Tobacco product litter may be a form of postconsumption marketing if the littered items are branded. We conducted an observational study in India to assess the presence of tobacco product litter and determine the proportion that included branding. METHODS: During November-December 2022, we identified tobacco product litter (cigarette/bidi butts and packaging; smokeless tobacco packaging) in nine Indian cities: Bengaluru, Bhubaneswar, Chennai, Delhi, Guwahati, Hyderabad, Lucknow, Mumbai and Patna. In each city, we conducted observations along 15 different routes, each approximately 250 m in distance, for a total of 135 observational routes. Data collectors classified each piece of tobacco litter (product/packaging) and recorded if the litter had visible branding, such as brand names and/or logos. RESULTS: The study identified 17 261 pieces of tobacco product litter; SLT packaging comprised the largest proportion of the sample (62%), followed by cigarette butts (26%), bidi butts (8%), cigarette packaging (3%) and bidi packaging (1%). Across the sample, 81% (n=13 924) of the litter was branded. A brand was visible on most packaging for cigarettes (98%), bidis (97%) and SLT (86%), and present on 82% of cigarette butts and 26% of bidi butts. CONCLUSION: This study found that the majority of tobacco product litter in India is branded, which could function as a form of postconsumption marketing. Plain and standardised packaging and banning branding features on filters would reduce tobacco litter branding.

Flavours and design features on tobacco product packaging near schools before and after plain packaging implementation in Montevideo, Uruguay.

INTRODUCTION: Monitoring tobacco industry marketing strategies in countries that have introduced plain packaging helps with documenting variations in the market during the transition period. Uruguay implemented plain packaging in February 2020. We describe changes in the characteristics of tobacco packaging, content and sticks before and after plain packaging implementation. METHODS: Data were collected across 15 neighbourhoods in different socioeconomic areas in Montevideo, Uruguay, before and after implementation (2019 and 2021). A high school or college was selected in each neighbourhood as the walking protocol starting point. Two stores were visited per neighbourhood. Cigarettes and roll-your-own tobacco (RYO) were purchased and coded for the presence of taste or sensation lexical and imagery features. RESULTS: The number of unique products increased between 2019 (n=23) and 2021 (n=40). Prior to implementation, all packs presented design features. After its implementation, 95.7% of cigarette packs complied with regulations. Overall, 34.7% of cigarettes and RYO were flavoured in 2019 versus 50.0% in 2021 (p=0.01). In 2019, all flavoured cigarette packs conveyed taste through language and/or imagery, while cigarettes had designs on the filter suggesting the potential for altering the flavour. In 2021, 44.0% of cigarette packs indicated flavour through lexicon; and 81.0% of cigarette sticks still included a flavour capsule. CONCLUSIONS: After implementation, we noticed an increase in the availability of unique flavoured cigarettes and RYO among surveyed retailers. However, this increase was less pronounced compared with what is reported in the Latin American region. Non-compliance was identified. Greater efforts should be made enforcing current policy.

Role of affective reactivity induced by cigarette packaging including graphic warning labels: the CASA Study.

OBJECTIVE: To identify whether three types of cigarette pack designs, including three versions of graphic warning label (GWL) plain packs, one GWL absent and branding absent pack (blank) and the smoker's own GWL absent and branding present pack (US), elicit different valence, type and levels of affect. DESIGN: US daily smokers (n=324) were asked to handle each of the five pack types and 'think aloud' their reactions. To avoid a muted familiarity response, exposure to their own US pack followed exposure to at least one GWL plain pack. Reactions were scored on a reactivity scale (-3 to +3) and the text was coded for speech polarity (-1 to +1) and emotive word frequency. RESULTS: Reactivity scores had excellent inter-rater reliability (agreement ≥86%; intraclass correlation coefficient ≥0.89) and were correlated with speech polarity (r=0.21-0.37, p<0.001). When considering their US pack, approximately two-thirds of smokers had a low (31.5%) to medium (34.6%) positive response (reactivity=1.29; polarity=0.14) with expressed feelings of joy and trust. Blank packaging prompted a largely (65.4%) neutral response (reactivity=0.03; polarity=0.00). The gangrenous foot GWL provoked mostly medium (46.9%) to high (48.1%) negative responses (reactivity=-2.44; polarity=-0.20), followed by neonatal baby (reactivity=-1.85; polarity=-0.10) and throat cancer (reactivity=-1.76; polarity=-0.08) warnings. GWLs varied in their elicitation of disgust, anger, fear and sadness. CONCLUSION: Initial reactions to GWL packs, a blank pack, and smokers' current US pack reflected negative, neutral, and positive affect, respectively. Different versions of the GWL pack elicited different levels and types of immediate negative affect.

Evaluating US smokers' willingness to pay for different cigarette packaging designs before and after real-world exposure in a randomised trial.

INTRODUCTION: Removal of tobacco industry branding from cigarette packs may reduce their appeal. Adding graphic warning labels (GWLs) should enhance this effect. We investigate whether willingness to pay for various packaging designs changes after 3 months' use of: (1) US branded packs without GWLs (US), (2) non-branded packs without GWLs (Blank), and (3) rotating non-branded packs with GWLs (gangrene; throat cancer; neonatal baby) covering >75% of pack (GWL). METHODS: Californian adult daily smokers not planning to quit (n=287; 56% female; mean age=39.6) completed a discrete choice purchase task before and after 3 months' experience using one of three packaging options. Conjoint analysis and pre-post modelling evaluated the change in importance of pack attributes and willingness to pay for US, Blank or GWL (blindness; teeth; gangrene) pack designs. RESULTS: Price determined ~70% of purchase choices, while pack design determined ~22%. Irrespective of intervention arm, US packaging generated appeal valuations compared with Blank packaging, while GWLs consistently provoked strong aversive valuations at baseline and follow-up. Compared with the US pack arm, using GWL packs for 3 months decreased willingness to pay for US packaging (ß=-$0.38, 95% CI -0.76 to 0.00). Wear-out effects were detected in the discount needed to willingly purchase the gangrene-GWL pack (ß=$0.49, 95% CI 0.16 to 0.82) and Blank pack (ß=$0.42, 95% CI 0.09 to 0.74) but not for GWLs (blindness, teeth) not used in trial. CONCLUSION: Compared with US branded packs, the negative valuation of non-branded GWL packs attenuates with even 3 months' use but does not generalise to non-used GWLs. This suggests that GWLs should be regularly refreshed. The appeal valuation of industry imagery suggests that the US plan to retain such imagery on packs may ameliorate the effect of GWLs.

Tobacco industry compliance with the EU track and tracing system in Lithuania.

BACKGROUND: The European Union (EU)-wide tobacco tracking and tracing system (T&T system) became operational on 20 May 2019, allowing a transitional period and gradual installation of the system until May 2020. This study attempts to assess the EU T&T system using a sample of discarded cigarette packs collected in Lithuania. METHODS: The empty pack survey was conducted between September 2019 and September 2020, covering both the transitional period and the period of full implementation. The study employed a two-stage cluster design by first randomly selecting 65 well-defined population clusters (30 cities and 35 towns) representing both urban and rural areas in all 10 counties in Lithuania. Second, we randomly selected 358 polling districts (routes) in each cluster. RESULTS: The fieldworkers walked at least 1074 km and collected 5727 discarded empty cigarette packs. None of the packs found during the EU T&T transitional period had a unique identifier (UI). After the full implementation of the EU T&T system, 32.0% of the collected packs were still without a UI. 5.8% of licit packs were without a UI after the May 2020 deadline. Most of the legal non-compliant packs (131, or 69.7%) were intended for the Lithuanian market. Close to 85% of packs that had duty-free markings were non-compliant. CONCLUSION: The tobacco industry most likely disregarded the EU T&T transitional period as no packs with UIs were found up until the full implementation. Packs without UIs were still found 4 months after the full implementation of the EU T&T system.

Addicted to green: priming effect of menthol cigarette packaging on brain response to smoking cues.

INTRODUCTION: Mentholated tobacco cigarettes are believed to be more addictive than non-menthol ones. Packaging of most menthol cigarette brands includes distinctive green hues, which may act as conditioned stimuli (ie, cues) and promote menthol smoking. To examine the cue properties of menthol cigarette packaging, we used a priming paradigm to assess the effect of packaging on the neural substrates of smoking cue reactivity. We hypothesised that menthol packaging will exert a specific priming effect potentiating smoking cue reactivity in menthol compared with non-menthol smokers. METHODS: Forty-two menthol and 33 non-menthol smokers underwent functional MRI while viewing smoking and neutral cues. The cues were preceded (ie, primed) by briefly presented images of menthol or non-menthol cigarette packages. Participants reported craving for cigarettes in response to each cue. RESULTS: Menthol packaging induced greater frontostriatal and occipital smoking cue reactivity in menthol smokers than in non-menthol smokers. Menthol packaging also enhanced the mediation by neural activity of the relationship between cue exposure and cigarette craving in menthol but not non-menthol smokers. Dynamic causal modelling showed stronger frontostriatal-occipital connectivity in response to menthol packaging in menthol compared with non-menthol smokers. The effects of non-menthol packaging did not differ between categories of smokers. CONCLUSIONS: Our findings demonstrate heightened motivational and perceptual salience of the green-hued menthol cigarette packaging that may exacerbate menthol smokers' susceptibility to smoking cues. These effects could contribute to the greater addiction severity among menthol smokers and could be considered in the development of science-based regulation and legal review of tobacco product marketing practices.

Effects of IQOS health warnings and modified risk claims among young adult cigarette smokers and non-smokers.

INTRODUCTION: Heated tobacco products, including Marlboro IQOS, are available globally. In the USA, IQOS was authorised to be advertised with claims about reduced toxicant exposure relative to cigarettes. The effects of such modified risk claims and health warnings have not been studied among young adult cigarette smokers and non-smokers. METHODS: In 2020, US young adult (18-30 years, n=1328) cigarette smokers and non-smokers viewed an IQOS ad in a 4 (modified risk claim variations or none) by 3 (warning variations or none) between-subjects experiment. Outcome measures assessed perceived credibility and effectiveness of the health or risk message for discouraging IQOS use, perceived harms, efficacy beliefs, and IQOS use intentions. RESULTS: Smokers reported significantly higher (p<0.05) perceived credibility, lower perceived effectiveness, higher efficacy beliefs about switching to IQOS and higher intentions to use IQOS than non-smokers. Among smokers, health warnings increased perceived credibility (p<0.001) and effectiveness (p<0.05), but claims did not affect outcomes examined. Among non-smokers, warnings and claims increased perceived credibility, and warnings increased perceived effectiveness (p<0.003). The reduced exposure claim increased non-smokers' intentions to use IQOS (b=0.40, 95% CI 0.07 to 0.73). CONCLUSIONS: Among young adult smokers, health warnings increased perceived effectiveness at discouraging IQOS use and perceived credibility. Among non-smokers, warnings and claims increased perceived credibility and warnings increased perceived effectiveness, but the Food and Drug Administration-authorised reduced exposure claim increased intentions to use IQOS. Research is warranted to understand how the content of modified risk claims and health warnings for IQOS affects IQOS use in this population.

Impact of e-liquid warning labels on young adults' perception of e-cigarettes and intention to use them: an experimental online study.

INTRODUCTION: Flavoured e-liquids are especially appealing to young adults. The objective of the present study was to evaluate the effects of text warning labels (WLs) on e-liquid vials used in flavoured electronic cigarettes (e-cigarettes) on e-cigarette non-users' perceptions of harm, addictiveness, emotional valence, interest in trying e-cigarettes and visual attention. METHODS: Young adults aged 18-25 years (n=313) who were non-e-cigarette users were recruited online and randomised to view images of one of two e-liquid vial conditions (with text WL or without text WL). Each participant was exposed to four images of e-liquid vials. After observing each image, participants reported interest in trying e-cigarettes, emotional valence, perceived harm and addictiveness. Additionally, participants completed an assessment of self-reported visual attention with a priori regions of interest (e-liquid branding and text WL). RESULTS: Separate two-way Analysis of Variance(ANOVA) that examined the main effects of sex and warning were used for each measure. Text WL on e-liquid vials decreased young adults' intention to use e-cigarettes (especially in men), increased harm perception and decreased appeal to the product. However, they did not influence the perceived addictiveness of e-cigarettes and rarely grabbed attention. Men perceived e-cigarettes as less harmful and less addictive. CONCLUSIONS: The results suggest that text WLs on e-liquid vials are moderately effective in preventing e-cigarette use in young adults. However, they capture less attention than the rest of the vial and fail to increase the perception of addictiveness. It is suggested to explore other types of design to increase the effectiveness of WLs.

Impact of standardised packaging in the UK on warning salience, appeal, harm perceptions and cessation-related behaviours: a longitudinal online survey.

INTRODUCTION: In the UK, since 20 May 2017, tobacco companies must sell cigarettes and rolling tobacco in standardised packs. METHODS: Three waves of a longitudinal online survey with smokers (≥16) before standardised packaging (wave 1 (W1): April to May 2016) and after standardised packaging (wave 2 (W2): September to November 2017; wave 3 (W3): May to July 2019). Of the 6233 smokers at W1, 4293 responded at W2 and 3175 at W3. We explored smokers' response to warning salience, appeal (appeal, quality, value, satisfaction and taste compared with a year ago), harm (harmfulness compared with a year ago, harm compared with other brands and whether some brands have more harmful substances), and quit plans, attempts and quitting. RESULTS: Compared with W1, the proportions noticing warnings first on packs, and rating cigarettes/rolling tobacco less appealing and worse value than a year ago, were higher at W2 and W3. Disagreeing that some brands contain more harmful substances was higher at W2. Interactions between social grade and survey wave for warning salience, and each appeal and harm outcome, were non-significant. Smokers switching from not noticing warnings first at W1 to noticing warnings first at W2, or who had a lower composite appeal score at W2, were more likely to plan to quit and to have made a quit attempt at W2. Smokers who switched to disagreeing that some brands contain more harmful substances at W2, after giving a different response at W1, were more likely to quit at W3. CONCLUSIONS: Standardised packaging appears to be having the intended impacts.
