Independent and combined effects of very low nicotine cigarette messages and e-cigarette messages: A randomised clinical trial
NCT05506046
Effects of freebase/protonated nicotine concentration, liquid composition and electrical power on throat hit in direct-to-lung vaping: Theory and clinical measurements
Nicotine throat hit can be predicted and manipulated through ENDS device and liquid design variables. Regulating ENDS throat hit is feasible and may help reduce product appeal to nicotine-naïve individuals while maintaining acceptability for smokers
Perceptions and intentions regarding Iqos among current US adults who use cigarettes and/or electronic nicotine delivery systems
Across tobacco use groups, there was varied interest and inclination to try IQOS and thus varied potential use as a complete substitute for cigarettes
I Crave a Blunt, I Don’t Crave a Cigarillo”: A Focus Group Study on Perceptions of Nicotine and Addiction among US Adults Who Currently Smoke Little Cigars or Cigarillos
While the US Food and Drug Administration (FDA)'s proposal to reduce the nicotine content in cigarettes is gaining traction, it is still undetermined whether the policy will also include other combustible tobacco products, such as little cigars and cigarillos (LCCs), and how such a policy should be communicated given the patterns of use and perceptions around LCCs. This study examined perceptions of nicotine and addiction related to LCC use and i…
General and Device-Specific Reasons for ENDS Use: A Qualitative Study with Adult ENDS Users
The reasons that adults choose to use ENDS are complex and sometimes related to both ENDS as a category and as specific ENDS product types. Regulations and public communication campaigns should reflect their ultimate objective and consider both general and specific motivations when attempting to achieve public health objectives
Evolution of tobacco products: Recent history and future directions
Declines in cigarette smoking prevalence in many countries and the consolidation of the tobacco industry have prompted the introduction of other forms of nicotine delivery. These include electronic nicotine delivery systems (ENDS), heated tobacco products (HTPs) and oral nicotine products (ONPs). Evolving over time, some of these products now deliver nicotine at levels comparable to cigarettes and may serve as effective substitutes for smokers. H…
Messaging about very low nicotine cigarettes (VLNCs) to influence policy attitudes, harm perceptions and smoking motivations: A discrete choice experiment
Harm and chemical information can be prioritised to ensure VLNCs are not misperceived as less harmful than regular cigarettes. Messages about increased quitting efficacy and reduced addictiveness associated with VLNCs may backfire if presented to those who do not smoke
Brief report on Iqos point-of-sale marketing, promotion and pricing in Iqos retail partner stores in Atlanta, Georgia, USA
Our study revealed a considerable amount of POS marketing and promotion for IQOS/HeatSticks at retail partner locations, visible to all retail consumers, including youth and non-smokers. This study was the first to examine IQOS POS marketing and promotion in the US context and findings add to the extant literature on IQOS global marketing strategies. As additional novel tobacco/nicotine products continue to enter the market, targeted monitoring o…
It’s Cool, Modifying and All, but I Don’t Want Anything Blowing Up on Me: ” A Focus Group Study of Motivations to Modify Electronic Nicotine Delivery Systems (ENDS)
Modifications of ENDS are ongoing and evolving among users and should be considered by the Food and Drug Administration (FDA) and other regulatory decision-makers as product authorization reviews are conducted and product standards are developed
It brings light to what you really put into your body’: A focus group study of reactions to messages about nicotine reduction in cigarettes
Messages communicating about nicotine reduction in cigarettes might help to motivate smokers to quit and can correct the misperceptions that VLNCs are less harmful. The FDA should consider specific target audiences and use different messages that complement each other in communicating about this regulation
What Motivates Smokers to Switch to ENDS? A Qualitative Study of Perceptions and Use
Switching completely from cigarettes to electronic nicotine delivery systems (ENDS) may reduce health risks for addicted smokers. This paper provides information about perceptions and other factors that may influence smokers' ENDS use and substitution for cigarettes. We conducted 12 online focus groups ( N = 61) among smokers who had never tried using ENDS (Never Users, N = 11), currently used both cigarettes and ENDS (Dual Users, N = 21), used b…
Users’ Modifications to Electronic Nicotine Delivery Systems (ENDS): Interviews with ENDS Enthusiasts
Users' modifications to electronic nicotine delivery systems (ENDS) products could increase initiation, inhibit cessation, or change the toxicity of the product. This study aims to begin to identify consumers' common ENDS modification behaviors. We conducted audio-recorded, in-depth one-on-one interviews with 13 adult ENDS users in the metropolitan Atlanta area, who self-reported extensive modification experience. Modifications to coils, batterie…
Urinary Acrylonitrile Metabolite Concentrations Before and after Smoked, Vaporized, and Oral Cannabis in Frequent and Occasional Cannabis Users
Cannabis use through smoking, vaping, or ingestion is increasing, but only limited studies have investigated the resulting exposure to harmful chemicals. N-acetyl-S-(2-cyanoethyl)-L-cysteine (2CYEMA), a urinary metabolite of acrylonitrile, a possible carcinogen, is elevated in the urine of past-30-day cannabis users compared to non-cannabis users. Five frequent and five occasional cannabis users smoked and vaped cannabis on separate days; one als…
Inferences beyond a claim: A typology of potential halo effects related to modified risk tobacco product claims
When tobacco products are marketed with modified risk tobacco product (MRTP) claims, consumers may infer additional health benefits not directly stated in the claims. We propose a typology of seven potential ‘halo effects’ (ie, an unintended generalisation) that may occur with MRTP marketing. Evidence currently exists that some of these types of halo effects occur after exposure to MRTP claims. These generalisations are likely unavoidable in cert…
Iqos debut in the USA: Philip Morris International’s heated tobacco device introduced in Atlanta, Georgia
Following the Food and Drug Administration’s (FDA) April 2019 authorisation on their premarket tobacco product application,1 Philip Morris (PM) has officially launched its heated tobacco product, IQOS, in the USA in October 2019 in Atlanta, Georgia. IQOS consists of a charger and a holder, into which tobacco sticks, called ‘HeatSticks’ in the USA, are inserted (figure 1). The blade in the holder heats tobacco in a HeatStick, producing an aerosol.…
Trends in Trust in the Sources of Health Information on E-Cigarettes Among US Adults, 2015–2017
Objectives. To evaluate recent levels and trends in trust in sources of health information on e-cigarettes in the United States. Methods. We obtained data from nationally representative samples of adults in 2015 (n = 5389), 2016 (n = 5273), and 2017 (n = 5389) that reported trust in 13 sources of health information on e-cigarettes in the United States. We used weighted linear regression models to examine temporal trends in trust levels. Results. …
Awareness and use of heated tobacco products among US adults, 2016–2017
Awareness and use of HTP in the USA are increasing. These products are more familiar to men and younger adults and may be being used disproportionately by racial/ethnic minorities. With increases in HTP availability and the potential for reduced-risk claims ahead, surveillance of patterns and consequences of use by both smokers and non-smokers is needed
Global surveillance of oral tobacco products: Total nicotine, unionised nicotine and tobacco-specific N -nitrosamines
These data have important implications for risk assessment because they show that very different exposure risks may be posed through the use of these chemically diverse oral tobacco products. Because of the wide chemical variation, oral tobacco products should not be categorised together when considering the public health implications of their use
Divergence between strength indicators in packaging and cigarette engineering: A case study of Marlboro varieties in Australia and the USA
Colour can be used to market cigarettes as 'milder', independently of ISO yields and 'Light'/'Mild' descriptors. Banning of 'Light' and 'Mild' brand descriptors may be inadequate to end belief in less harmful cigarettes so long as the tobacco industry remains free to engineer 'mildness' and to use colours, other descriptors and design features to characterise varieties it wants to market as 'milder
Determination of tar, nicotine, and carbon monoxide yields in the mainstream smoke of selected international cigarettes
Analysis of the smoke deliveries suggested that cigarettes from the Eastern Mediterranean, Southeast Asia, and Western Pacific WHO regions tended to have higher tar, nicotine, and CO smoke deliveries than did brands from the European, American, or African WHO regions surveyed
