Greenwashed Cigarette Ad Text and Imagery Produce Inaccurate Harm, Addictiveness, and Nicotine Content Perceptions: Results from a Randomized Online Experiment.

Introduction: The tobacco industry has a long history of circumventing regulations to present their products, inaccurately, as less harmful. Greenwashing (portraying a product as natural/eco-friendly) is increasingly used by tobacco companies and may mislead consumers to believe that certain cigarettes are less harmful than others. This study assesses the effect of some common greenwashing tactics on consumer product perceptions.

The objective of this paper is to describe two methods for implementing digital twins at water resource recovery facilities and highlight and discuss their differences and preferable use situations, with focus on the automated data transfer from the real process.

Would banning menthol cigarettes, flavored cigars, and flavored e-cigarettes prompt users to seek illicit channels for obtaining them in the United States?

Background: Banning flavors in tobacco and nicotine products may reduce youth initiation and prompt quit attempts but such bans may lead to illicit markets. We examined how likely current users would be to seek flavored products from illicit channels under various ban scenarios.

Methods: Cross-sectional surveys of 2552 current users of menthol cigarettes or flavored cigars and 2347 users of flavored e-cigarettes were conducted between 2021 and 2022 in the United States.

The impact of flavored e-cigarette bans on e-cigarette use in three US states.

Introduction: Beginning in 2019, several U.S. states implemented temporary or permanent bans on the sale of flavored e-cigarettes.

Reactions to hypothetical flavor bans among current users of flavored e-cigarettes.

Banning flavors in e-cigarettes and other tobacco products may decrease their use. To examine how current users of flavored e-cigarettes might react to a ban on flavored e-cigarettes when: (i) menthol flavor is banned together with other flavors, or (ii) this ban on e-cigarettes is combined with a ban on menthol cigarettes and flavored cigars. A national cross-sectional survey of 2,347 current users of flavored e-cigarettes was conducted in May 2022.

Comparison of guideline- and model-based WWTP design for uncertain influent conditions.

In this study, two methods for wastewater treatment plant (WWTP) dimensioning were compared: (1) a traditional guideline-based approach, and (2) a mechanistic model-based approach. The design outputs depended on uncertainties in correlated influent concentrations, which emphasises the importance of uncertainty analysis. The results showed that model-based design could simplify and reduce the time required for uncertainty and sensitivity analysis compared to a conventional design approach, in which the equations are solved manually and iteratively.

Perfusion-Limited Hypoxia Determines the Outcome of Radiation Therapy of Hypoxic Tumours.

Despite advancements in functional imaging, the resolution of modern techniques is still limited with respect to the tumour microenvironment. Radiotherapy strategies to counteract e.g.

Should menthol e-cigarettes be banned? Reaction of adult smokers and users of e-cigarettes to hypothetical bans.

Introduction: This study examines how current smokers using menthol cigarettes or flavoured cigars, and current users of flavoured e-cigarettes may respond to three hypothetical flavour-ban scenarios: (1) banning only menthol cigarettes and flavoured cigars; (2) also banning e-cigarettes with any non-tobacco flavours except menthol; and (3) also banning e-cigarettes with any non-tobacco flavours, including menthol.

Methods: Recruited from mTurk, respondents were asked if they would quit all tobacco-nicotine use or continue or start using products that were still legally available. The patterns of responding to each ban scenario, for both flavoured smokers and users of non-tobacco flavoured e-cigarettes, were summarised.

To calibrate or not to calibrate, that is the question.

Sensors used for control have become widespread in water resources recovery facilities during the strive for resource efficient operations. However, their accuracy is reliant on uncertain laboratory measurements, which are used for calibration and, in turn, to correct for sensor drift. At the same time, current sensor calibration practices are lacking clear theoretical understanding of how measurement uncertainties impact the final control action.

Risk and safety profile of electronic nicotine delivery systems (ENDS): an umbrella review to inform ENDS health communication strategies.

Objectives: This umbrella review aims to summarise the evidence about electronic nicotine delivery systems' (ENDS) risk and safety health profile to inform ENDS health communication strategies.

Data Sources And Study Selection: Six databases were searched for systematic reviews presenting evidence on ENDS-related health effects. Ninety reviews divided into five categories were included: toxicity=20, health effects=40, role in smoking cessation=24, role in transition to combustible cigarettes (CCs)=13 and industry marketing claims=4.

How Smokers of Menthol Cigarettes and Flavored Cigars Might Respond to FDA's Proposed Bans.

Introduction: A ban on menthol cigarettes and flavored cigars may reduce smoking and tobacco-related disparities.

Aims And Methods: We aimed to examine the response of current smokers to a hypothetical ban on menthol cigarettes and flavored cigars. Current smokers were recruited online and reported the alternative products that they may switch to under a hypothetical ban, if they would try to obtain the banned products from illicit channels, and their support to the ban.

Tax incidence of electronic nicotine delivery systems (ENDS) in the USA.

Background: A growing number of states or jurisdictions in the USA have imposed excise taxes on electronic nicotine delivery systems (ENDS). However, there is no consensus on how best to tax ENDS.

Objectives: We specifically compare the tax incidence or burden for ENDS and cigarettes and analyse how ENDS tax incidence is associated with the choices of tax bases and rates.

Metrics for environmental compensation: A comparative analysis of Swedish municipalities.

Environmental compensation (EC) aims at addressing environmental losses due to development projects and involves a need to compare development losses with compensation gains using relevant metrics. A conceptual procedure for computing no net loss is formulated and used as a point of departure for a comparative analysis of metrics used by five Swedish municipalities as a part of their EC implementation in the spatial planning context of detailed development plans. While Swedish law does not require EC in this context, these municipalities have still decided to introduce EC requirements for development projects that occur on municipality-owned land and to promote voluntary EC among private actors in development projects on private land.

Impact of flavours, device, nicotine levels and price on adult e-cigarette users' tobacco and nicotine product choices.

Introduction: To understand the impact of e-cigarette devices, flavours, nicotine levels and prices on adult e-cigarette users' choices among closed-system and open-system e-cigarettes, cigarettes and heated tobacco products (HTPs).

Methods: Online discrete choice experiments were conducted among adult (≥18 years) e-cigarette users (n=2642) in August 2020. Conditional logit regressions were used to assess the relative impact of product attributes and the interactions between product attributes and user characteristics, with stratified analyses to examine differences by smoking status and primarily used e-cigarette device and flavour.

Perceived health risks associated with the use of tobacco and nicotine products during the COVID-19 pandemic.

Introduction: The perceived health risks of tobacco products may change during the ongoing COVID-19 pandemic. This study aimed to examine the perceived risks of tobacco use on COVID-19 infection and severity, and possible COVID-related changes in perceptions of tobacco use and overall health.

Methods: We conducted an online survey of adults in the United States in June 2020 (n=2097).

Sensor bias impact on efficient aeration control during diurnal load variations.

This study highlights the need to increase our understanding of the interplay between sensor drift and the performance of the automatic control system. The impact from biased sensors on the automatic control systems is rarely considered when different control strategies are assessed in water resource recovery facilities. Still, the harsh measurement environment with negative effects on sensor data quality is widely acknowledged.

Evaluation of environmental impacts for future influent scenarios using a model-based approach.

Changes in dilution of wastewater to a treatment plant due to infiltration or surface runoff can have a great impact on treatment process performance. This paper presents a model-based approach in which realistic influent scenarios are generated and used as inputs to a dynamic plant-wide process model of the wastewater treatment plant. The simulated operation is subsequently evaluated using life-cycle assessment (LCA) to quantify the environmental impacts of the future influent scenarios.

Identification of behavioural model input data sets for WWTP uncertainty analysis.

Uncertainty analysis is important for wastewater treatment plant (WWTP) model applications. An important aspect of uncertainty analysis is the identification and proper quantification of sources of uncertainty. In this contribution, a methodology to identify an ensemble of behavioural model representations (combinations of input data, model structure and parameter values) is presented and evaluated.

Agent-based Modeling in Tobacco Regulatory Science: Exploring 'What if' in Waterpipe Smoking.

Objectives: Waterpipe tobacco smoking (WTS) is an emerging public health crisis, particularly among youth and young adults. Different from the use of other tobacco products and e-cigarettes, WTS tends to be a social activity occurring among friends or persons associated with social networks. In this paper, we review a potential strategy for WTS-related research.

The Association of E-cigarette Flavors With Satisfaction, Enjoyment, and Trying to Quit or Stay Abstinent From Smoking Among Regular Adult Vapers From Canada and the United States: Findings From the 2018 ITC Four Country Smoking and Vaping Survey.

Aims: This study examined whether nontobacco flavors are more commonly used by vapers (e-cigarette users) compared with tobacco flavor, described which flavors are most popular, and tested whether flavors are associated with: vaping satisfaction relative to smoking, level of enjoyment with vaping, reasons for using e-cigarettes, and making an attempt to quit smoking by smokers.

Methods: This cross-sectional study included 1603 adults from Canada and the United States who vaped at least weekly, and were either current smokers (concurrent users) or former smokers (exclusive vapers). Respondents were categorized into one of seven flavors they used most in the last month: tobacco, tobacco-menthol, unflavored, or one of the nontobacco flavors: menthol/mint, fruit, candy, or "other" (eg, coffee).

The impact of a comprehensive tobacco product flavor ban in San Francisco among young adults.

Objective: Flavors play an important role in the initiation and use of tobacco products. The FDA, states, and cities have been implementing or considering banning flavored e-cigarettes or any flavored tobacco products. This study empirically assessed the impact of one of the first comprehensive bans of all flavored tobacco products other than tobacco-flavored e-cigarettes among young adults in San Francisco, California.

International differences in patterns of cannabis use among adult cigarette smokers: Findings from the 2018 ITC Four Country Smoking and Vaping Survey.

Background: Although evidence shows that co-use of cigarettes and cannabis is common, there is little research examining if co-use patterns vary depending on the regulatory environment for cannabis. This study examined patterns of co-use and perceptions of relative harm among cigarette smokers in four countries with different histories, and at different stages of cannabis legalization.

Methods: Data are from the 2018 International Tobacco Control 4CV Survey and included 10035 adult cigarette smokers from Canada, United States (US), Australia, and England.

Has FDA abandoned its efforts to make fake-cigar cigarettes comply with federal tobacco control laws that apply to cigarettes but not cigars?

In the USA, legal definitions of cigarettes and cigars are critical to tobacco control policy because federal, state and local laws typically tax and regulate cigarettes more strictly than cigars. In 2016, near the end of the Obama Administration, the US Food and Drug Administration (FDA) sent warning letters to four filtered 'little cigar' manufacturers stating that their so-called 'cigars' were cigarettes and, therefore, subject to more stringent public health restrictions. Documents produced in response to a Freedom of Information Act request show that without explanation or public notice FDA has abandoned its prior determination that the manufacturers' 'little cigars' were actually cigarettes and, consequently, were violating the ban on flavoured cigarettes in the Family Smoking Prevention and Tobacco Control Act (TCA).
