<h3>Introduction</h3> Electronic cigarettes (ECIGs) aerosolise a liquid that usually contains propylene glycol and/or vegetable glycerine, flavourants and the dependence-producing drug, nicotine, in various concentrations. This laboratory study examined relationship between nicotine concentration plasma puffing behaviour experienced ECIG users. <h3>Methods</h3> Sixteen ECIG-experienced participants used 3.3-Volt battery attached to 1.5-Ohm dual-coil 'cartomiser' loaded with 1 mL of flavoured...
Electronic cigarette (ECIG) nicotine delivery and other effects may depend on liquid concentration user experience. This study is the first to systematically examine influence of ECIG experience delivery, heart rate, puff topography, subjective effects. Thirty-three ECIG-experienced individuals 31 ECIG-naïve smokers completed 4 laboratory conditions consisting 2, 10-puff bouts (30-sec interpuff interval) with a 3.3-V battery attached 1.5-Ω "cartomizer" (7.3 W) filled 1 ml liquid. Conditions...

Introduction:Electronic cigarettes (ECIGs) aerosolize a liquid that usually contains propylene glycol and/or vegetable glycerin, flavorants, and the dependence-producing drug nicotine in various concentrations. This study examined extent to which ECIG concentration is related user plasma ECIG-naïve tobacco cigarette smokers.
Electronic cigarette (ECIG) nicotine delivery and other effects can be influenced by device and/or liquid characteristics user puffing behavior. One class of ECIGs includes "sub-ohm" devices that incorporate heating coils with resistance less than 1 ohm (Ω), lower observed in conventional (e.g., ≥1.5 Ω). Relative to operate at ≤10 W, low-resistance used increase power 40-300 W). However, little is known about the individual combined ECIG power, manipulated coil resistance, concentration on...
JUUL is an electronic cigarette that aerosolises a nicotine-containing liquid, while IQOS heats tobacco to produce aerosol. Both are marketed smokers, but their effects have seldom been examined in this population.
Abstract Introduction Coronavirus Disease 2019 (COVID-19) is a public health crisis, but its effects on tobacco users remain ill-defined. This report aimed to assess the relationship between product-specific risk perceptions for COVID-19 and changes in use since start of pandemic. Methods A sample (n = 776) past-30 day exclusive smokers 238), e-cigarette 143), dual 395) residing US aged 18 or older were collected using Mechanical Turk from April 27 June 8, 2020. Adjusted associations (ie...
In total, 3.2% of American adults report using e-cigarettes every day or some days. The Vaping and Patterns E-cigarette Use Research (VAPER) Study is a web-based longitudinal survey designed to observe patterns in device liquid use that suggest the benefits unintended consequences potential e-cigarette regulations. heterogeneity devices liquids on market, customizability liquids, lack standardized reporting requirements result unique measurement challenges. Furthermore, bots takers who...
ABSTRACT Aims Cigarette smoking causes cancer and disease, yet people find quitting difficult due to aversive symptoms that accompany tobacco abstinence. Understanding how suppress these is critical in developing effective cessation treatments. Pharmacologically, pure nicotine suppresses abstinence partially, non‐nicotine, smoking‐related stimuli fully, at least for 24 hours. The current study was designed clarify the impact of on withdrawal, explore duration their ability withdrawal...
Electronic cigarettes e-cigarettes aerosolize a liquid solution often containing nicotine. e-cigarette nicotine delivery may be influenced by user puffing behaviors ("puff topography"). E-cigarette puff topography can recorded using mouthpiece-based computerized systems. The present study sought to examine the extent which these systems influence and other associated acute effects under ad libitum use conditions.Plasma concentration, heart rate, subjective were assessed in 29 experienced...
Background: COVID-19 has caused health impacts and disruptions globally. Electronic cigarette (ECIG) users may face additional impacts. This study examined of on ECIG users. Methods: Concept mapping, a mixed-methods approach, was used to identify adult (n = 93) provided statements completing prompt: “A specific way Coronavirus/COVID-19 affected my vaping/e-cigarette use, related purchasing, or other behaviors issues is…”. Participants generated 85 unique statements, sorted into groups...
Significance IQOS is a heated tobacco product that has been widely advertised by Philip Morris International (PMI) as reduced-exposure compared with cigarettes. Reduced exposure results from reduced emission of toxicants which could be influenced constituents and user behaviour. This study aims to assess the influence behaviour, including device cleaning puffing parameters, on toxicant emissions IQOS. Methods aerosols were generated smoking machine using combination two protocols (after 1...
Smoking-related cancer and other disease account for more than 400,000 U.S. deaths annually. Smoking cessation reduces smoking-related rates, but relapse rates are high. Thus, interest in reducing the harm of continued smoking is growing. Potential reduced exposure products (PREPs) marketed to reduce smokers' smoke toxicants such as carbon monoxide (CO) carcinogens may be reduction tools. New PREPs proliferating, past experience with "low-yield" cigarettes that failed toxicant suggests...
Harm reduction for tobacco smokers may involve reducing their exposure to lethal smoke constituents. Assessing constituent and any resulting harm from a potential reduced-exposure product (PREP) will preclinical, clinical, epidemiological research. The purpose of this study was evaluate clinical laboratory model assessing the acute effects PREPs smokers. Philip Morris' Accord R.J. Reynolds' Eclipse were used as examples. Twenty overnight-abstinent (> 15 'light' or 'ultra-light'...
How nicotine dependence will be affected when current smokers initiate electronic cigarette (e-cigarette) use to reduce smoking is unknown. This study evaluated cigarette, e-cigarette, and total more than 6 months among reducing consumption by replacing with e-cigarettes.Adult were randomized one of four conditions (36 mg/ml 8 0 or cigarette-substitute [CS] [provided at no cost]) instructed their 75% 1 month. Participants completed follow-up 1, 3, months. The Penn State Nicotine Dependence...
Biomarkers such as carbon monoxide (CO) and cotinine (a nicotine metabolite) are used in tobacco cessation studies to assess smoking status. CO is easy assess, inexpensive, provides immediate results. However, the short half-life of may limit its ability identify smokers who have abstained for several hours. Quantitative methods (e.g., gas chromatography/mass spectrometry, or GC/MS) measuring urine cotinine, which has a longer half-life, valid reliable, though costly time consuming. Recently...
A basic tenet of empirical research on cigarette smoking behavior is the systematic assessment patterns use. However, large majority extant relies smokers' retrospective reports their average number cigarettes per day (CPD), a measure that may be variable in terms reliability and validity. Using data from 3 previously published studies non-treatment-seeking daily smokers (combined N = 89), this analysis examined self-reported CPD, consistency returned butts each over 4 consecutive 24-hr...
Under certain conditions, electronic cigarettes (e-cigs) can deliver nicotine to and suppress tobacco abstinence symptoms in cigarette smokers. Growing popularity of e-cigs raises abuse liability concerns. This study's purpose was compare the an e-cig (1.5 Ohm, 3.3 V) filled with 36 mg/mL or 0 Food Drug Administration (FDA)-approved inhaler (IN) participants' own brand (OB) cigarettes. Smokers (N = 24) completed four sessions which they multiple-choice procedure, plasma concentration...
