Tobacco Control最新文献

Introduction: The direct morbidity and mortality caused by tobacco are well documented, but such products also contribute to a range of environmental pollutants resulting from tobacco product waste. No previous studies have yet quantified tobacco product waste in a low-income and middle-income country (LMIC). This study estimates the potential annual waste generated due to consumption of smoked and smokeless tobacco products in India and its states.

Methodology: We systematically collected samples of smoked and smokeless tobacco products from 33 districts of 17 Indian states/union territories. Stratified weights of plastic, paper, foil and filter packaging components, and gross empty package weights were recorded. Prevalence of smoking and smokeless tobacco use at national and state-level estimates was derived from the Global Adult Tobacco Survey (2016-2017) to quantify waste potentially generated by tobacco products.

Results: We included 222 brands of tobacco products (70 cigarette, 94 bidi and 58 smokeless tobacco brands) in the final analysis. A total of 170 331 (±29 332) tonnes of waste was estimated to be generated annually, out of which 43.2% was plastic, 3.6% was foil and 0.8% was filter. Two-thirds of the overall waste was contributed by smokeless products alone. Maximum waste was generated in Uttar Pradesh (20.9%; 35 723.7±6151.6 tonnes), Maharashtra (8.9%; 15 116.84±2603.12 tonnes) and West Bengal (8.6%; 14 636.32±2520.37 tonnes).

Conclusion: This study provides first of its kind national-level evidence on the types (plastic, paper, foil and filter) and quantity of waste potentially generated by use of tobacco products in India. Similar studies from other LMICs can serve to raise consciousness about many negative environmental impacts of tobacco products and need for policies to address them.

Objective: The goal was to analyse website content of Chinese electronic (e) cigarette manufacturing enterprises and understand the marketing strategies to provide evidence for decision-makers to regulate manufacturers.

Methods: Through QCC.com, one of the largest enterprise information query platforms in China, we identified 104 official manufacturer websites in 2021. A codebook including 6 sections with 31 items was developed and all webpages were coded separately by two trained researchers.

Results: Over half of the websites (56.7%) did not have age verification for entry. Thirty-two (30.8%) websites had no restriction for minors to use or purchase e-cigarettes, and 79 (76.0%) had no health warning. Overall, 99 websites (95.2%) displayed their products, and 72 (69.2%) displayed e-flavours. The most frequently used descriptions of products included good taste (68.3%), positive mood (62.5%), leakage resistance (56.7%), enjoyment (47.1%), reduced harm (45.2%), alternatives to cigarettes (43.3%) and long battery life (42.3%). Additionally, 75 websites (72.1%) provided contact information on different channels, including WeChat (59.6%), Weibo (41.3%), Facebook (13.5%), Instagram (12.5%) and brand apps (2.9%). Manufacturers provided investment and franchise information (59.6%) and offline store information (17.3%). In addition, 41.3% websites included content regarding corporate social responsibility.

Conclusions: Chinese e-cigarette manufacturers' official websites have become a platform for presenting product and brand information, establishing online and offline marketing loops, and displaying corporate social responsibility with weak age restrictions on access and a lack of health warnings. The Chinese government should implement strict regulatory measures on e-cigarette enterprises.

Aim: Ireland will not meet the tobacco endgame goal set in its 2013 Tobacco-Free Ireland (TFI) policy of reducing smoking prevalence to less than 5% by 2025. Public opinion on tobacco endgame, a key lever to realise this goal, is uncharted in Ireland. This study aimed to measure public knowledge and attitudes to tobacco endgame.

Methods: A telephone-administered cross-sectional survey of 1000 randomly dialled members of the general public was conducted in 2022. Prevalence of awareness, perceived achievability and support for the TFI goal and tobacco endgame measures was calculated and compared across tobacco product use status. Logistic regression identified factors independently associated with goal support.

Findings: Although TFI goal awareness was low (34.0%), support was high (74.6%), although most (60.2%) believed it achievable beyond 2025. Product-focused measures were popular while support for supply-focused measures was mixed: for example, 86.1% supported nicotine content reduction while 40.3% supported user licencing. Phasing out tobacco sales was highly supported (82.8%); for most, this was contingent on support for currently addicted users. TFI goal support was independently associated with female sex (adjusted odds ratio (aOR) 1.47, 95% CI 1.05 to 2.07), higher education (aOR 1.80, 95% CI 1.21 to 2.66) and non-tobacco product use (aOR 2.67, 95% CI 1.66 to 4.30).

Conclusions: Despite low awareness, tobacco endgame support is strong in Ireland. Public appetite for radically reducing tobacco product appeal and availability combined with public views on endgame achievability subject to extended timelines should be used to re-invigorate tobacco endgame discussion and planning in countries at risk of failing to meet declared targets.

Background: In November 2021, the Tobacconomics team published the second edition of the Cigarette Tax Scorecard which evaluates cigarette taxation in each country based on four components-cigarette price, affordability change, tax share and tax structure. This study examines the relationship between the overall cigarette tax score and tobacco excise tax revenue between 2014 and 2018.

Methods: Using cigarette tax scores from the Tobacconomics Cigarette Tax Scorecard and tobacco excise tax revenue information from WHO, this analysis is based on ordinary least squares estimations to assess the association between the overall cigarette tax scores and tobacco excise tax revenues per capita controlling for countries' tobacco control environment, sociodemographic characteristics and country and year fixed effects.

Results: A 1-point higher overall cigarette tax score is associated with higher tobacco excise tax revenue per capita of $11.98 (in constant 2018 purchasing power parity international dollars). For low and middle-income countries and lower performing countries at baseline, a 1-point higher overall cigarette tax score is associated with higher tobacco excise tax revenue per capita of $11.32 and $6.92, respectively. If all countries had increased their scores to '5', the tobacco excise tax revenue per capita would have increased by 22.51%.

Conclusions: Higher overall cigarette tax scores are associated with higher tobacco excise tax revenue per capita. Countries aiming to reach higher cigarette tax scores would be able to reduce tobacco use and increase their tobacco tax revenue, which can be allocated to development priorities.

Background: Massachusetts was the first to implement a state-wide menthol cigarette sales restriction in the USA. Following its implementation in June 2020, evidence showed declines in cigarette sales in Massachusetts; however, changes in nicotine replacement therapy (NRT) product sales are unknown.

Methods: This cohort study analysed NRT products sold by US-based retailers available in 26 states from the Nielsen Retail Scanner Data. Outcomes were state-level 4-week aggregate sales of gum, lozenge and patch NRT products converted into pieces per 1000 adults (aged ≥18 years) who smoke cigarettes based on smoking rates from the Behavioral Risk Factor Surveillance System and corresponding population from the US Census Bureau. We used a difference-in-differences method to compare changes in NRT product sales in Massachusetts before (1 January 2017 to 13 June 2020) and after (14 June 2020 to 4 December 2021) the policy with sales in 25 states.

Results: The analysis included 1664 observations for each NRT product, with 1170 from before and 494 from after the policy change. The 4-week NRT product sales per 1000 adults who smoke cigarettes in Massachusetts compared with the comparison states increased for gums by 643.11 (95% CI 365.33 to 920.89; p<0.001) pieces or 12.9% and for lozenges by 436.97 (95% CI 292.88 to 581.06; p<0.001) pieces or 17.9% but no statistically significant change in patches after implementing the policy.

Conclusion: The increases in sales of gum and lozenge NRT products in Massachusetts after implementing the policy suggest that a nationwide ban on menthol cigarettes can increase NRT product use; therefore, interventions are needed to strengthen cessation support for adults who smoke cigarettes but intend to quit.

Background: An increasing number of countries are pursuing a tobacco 'endgame'. We sought to determine the combination of measures it would take to achieve a tobacco endgame in the city-state of Singapore.

Methods: Using an open-cohort microsimulation model, we estimated the impact of existing measures (quit programmes, tobacco taxes, flavours ban) and more novel measures (very low nicotine cap, tobacco-free generation, raising the minimum legal age to 25 years), and combinations thereof, on smoking prevalence in Singapore over a 50-year horizon. We used Markov Chain Monte Carlo to estimate transition probabilities between the states of never smoker, current smoker and former smoker, updating each individual's state across each year with prior distributions derived from national survey data.

Results: Without new measures, smoking prevalence is expected to rebound from 12.2% (2020) to 14.8% (2070). The only scenarios to achieve a tobacco endgame target within a decade are those combining a very low nicotine cap with a flavours ban. A nicotine cap or tobacco-free generation alone also achieve endgame targets, but after 20 and 39 years, respectively. Taxes, quit programmes, a flavours ban and minimum legal age increase do augment the impact of other measures, but even when combined are insufficient to achieve a tobacco endgame target within 50 years.

Conclusion: In Singapore, achieving a tobacco endgame within a decade requires a very low nicotine cap coupled with a tobacco flavours ban, although this target can also be achieved in the long term (within 50 years) with a tobacco-free generation.

Background: We aim to assess the effect of a smoke-free beaches (SFB) intervention in Barcelona on smoking during the 2021 bathing season.

Methods: Quasi-experimental pre-post design (pre-intervention period: 15-28 May; post-intervention period: 29 May-12 September). Based on users' profiles and location, four beaches were assigned to the intervention group (IG) and five to the comparison group (CG). The intervention involved: a mayoral decree (29 May), a communication campaign and beach on-site information. We established two 3 m × 3 m transects per beach from the coastline to the promenade. Trained teams collected smoking-related information in the transects through observations and surveys to beach users. Outcomes are as follows: percentage of people reporting witnessing smoking behaviours the last fortnight and percentage of people observed smoking. We calculated and compared prevalence ratios (PRs) with adjusted Poisson regressions.

Results: 3751 interviews (1721 IG; 2030 CG) and 1108 observations (498 IG, 610 CG) were carried out. SFB were associated with a significant reduction in the percentage of people reporting witnessing smoking (IG (pre: 87.2%; post: 49.7%); CG (pre: 86.2%; post: 74.1%); PR (95% CI): 0.7 (0.6 to 0.8)); and in the users observed smoking in the beach (IG (pre: 3.8%; post: 3.0%); CG (pre: 2.3%; post: 9.9%); PR (95% CI): 0.3 (0.3 to 0.4)). Satisfaction scores were 8.3 (IG) and 8.1 (CG) out of 10.

Conclusion: An SFB intervention is an effective and well-accepted measure to reduce smoking and smokers' visibility. Smoke-free measures should be extended to beaches and other non-regulated outdoor areas.
