INTRODUCTION: Electronic cigarette (e-cigarette) use, or vaping, is increasing against a backdrop of declining smoking rates. E-cigarettes contain fewer toxicants than cigarettes, but their appearance and mode of use has the potential to satisfy the habitual aspects of smoking. To date, we know little about lay perceptions of the safety of using e-cigarettes in pregnancy. METHODS: We conducted a thematic discourse analysis of 13 online discussion forum threads that discussed e-cigarette use during pregnancy...

We examine differences between college students and non-students with respect to orientation toward e-cigarettes. Participants were U.S. adults 18-24 (465 students, 409 non-students). Data collection employed an online survey by GfK Custom Research. Smoking, vaping, and use of alternate tobacco were assessed, as were variables from the Theory of Reasoned Action and Diffusion of Innovations. This study showed that smoking status largely explains use and orientation toward electronic cigarettes among both students and non-students, with differences attributable to higher smoking rates among non-students...

INTRODUCTION: Electronic cigarettes' (e-cigarettes) viability as a public health strategy to end smoking will likely be determined by their ability to mimic the pharmacokinetic profile of a cigarette while also exposing users to significantly lower levels of harmful/potentially harmful constituents (HPHCs). The present study examined the nicotine delivery profile of third- (G3) versus second-generation (G2) e-cigarette devices and their users' exposure to nicotine and select HPHCs compared with cigarette smokers...

INTRODUCTION: Vaping has increased in popularity, and the potential harms and benefits are largely unknown. Vaping-related advertising is expected to grow as the vaping industry grows; people are exposed primarily to vaping advertisements on the Internet, and Twitter is an especially popular social medium among young people. The primary objective of our study was to describe the characteristics of vaping-related advertisements on Twitter. METHODS: We collected data on 403,079 English-language tweets that appeared during November 2014 and contained vaping-related keywords...

This overview covers a wide range of cannabis topics, initially examining issues in dispensaries and self-administration, plus regulatory requirements for production of cannabis-based medicines, particularly the Food and Drug Administration "Botanical Guidance." The remainder pertains to various cannabis controversies that certainly require closer examination if the scientific, consumer, and governmental stakeholders are ever to reach consensus on safety issues, specifically: whether botanical cannabis displays herbal synergy of its components, pharmacokinetics of cannabis and dose titration, whether cannabis medicines produce cyclo-oxygenase inhibition, cannabis-drug interactions, and cytochrome P450 issues, whether cannabis randomized clinical trials are properly blinded, combatting the placebo effect in those trials via new approaches, the drug abuse liability (DAL) of cannabis-based medicines and their regulatory scheduling, their effects on cognitive function and psychiatric sequelae, immunological effects, cannabis and driving safety, youth usage, issues related to cannabis smoking and vaporization, cannabis concentrates and vape-pens, and laboratory analysis for contamination with bacteria and heavy metals...

INTRODUCTION: Product characteristics that impact e-cigarette appeal by altering the sensory experience of vaping need to be identified to formulate evidence-based regulatory policies. While products that contain sweet flavorings and produce a "throat hit" (i.e., desirable airway irritation putatively caused by nicotine) are anecdotally cited as desirable reasons for vaping among young adults, experimental evidence of their impact on user appeal is lacking. This experiment applied a novel laboratory protocol to assess whether: (1) sweet flavorings and nicotine affect e-cigarette appeal; (2) sweet flavorings increase perceived sweetness; (3) nicotine increases throat hit; and (4) perceived sweetness and throat hit are associated with appeal...

INTRODUCTION: This study documented images posted on Instagram of electronic cigarettes (e-cigarette) and vaping (activity associated with e-cigarette use). Although e-cigarettes have been studied on Twitter, few studies have focused on Instagram, despite having 500 million users. Instagram's emphasis on images warranted investigation of e-cigarettes, as past tobacco industry strategies demonstrated that images could be used to mislead in advertisements, or normalise tobacco-related behaviours...

BACKGROUND: Dabbing is an emerging method of marijuana ingestion. However, little is known about dabbing owing to limited surveillance data on dabbing. OBJECTIVE: The aim of the study was to analyze Google search data to assess the scope and breadth of information seeking on dabbing. METHODS: Google Trends data about dabbing and related topics (eg, electronic nicotine delivery system [ENDS], also known as e-cigarettes) in the United States between January 2004 and December 2015 were collected by using relevant search terms such as "dab rig...

INTRODUCTION: The present study examined the influence of flavouring on the smoking and vaping behaviour of cigarette smokers asked to adopt e-cigarettes for a period of 6 weeks. METHODS: Participants were 88 current male and female smokers with no intention to stop smoking, but who agreed to substitute e-cigarettes for their current cigarettes. On intake, participants were administered tests of taste and smell for e-cigarettes flavoured with tobacco, menthol, cherry and chocolate, and were given a refillable e-cigarette of their preferred flavour or a control flavour...

Vaping nicotine (i.e., the use of e-cigarettes and similar devices to inhale nicotine) is becoming increasingly popular among young people. Though some vaporizers are capable of vaporizing cannabis, sparse research has investigated this method of cannabis administration. The present study examines the prevalence and correlates of vaping cannabis in a sample of 482 college students. Participants reported high lifetime rates of vaping nicotine (37%) and cannabis (29%). Men (rs = 0.09, p = .047) and individuals from higher socioeconomic status families (rs = 0...

INTRODUCTION: E-cigarettes are popular in the United States, but psychometrically sound measures of vaping beliefs and behaviors are lacking. METHODS: We evaluated the psychometrics of the Short-Form Vaping Consequences Questionnaire (S-VCQ), a modified version of the Short-Form Smoking Consequences Questionnaire that assesses expectancies for negative consequences, positive reinforcement, negative reinforcement, and appetite/weight control associated with vaping...

INTRODUCTION: A challenge in Electronic Nicotine Delivery System (ENDS) research is how to refer to these devices in ways that are meaningful to current or potential users. The objectives of this study were to: (1) describe the frequency of ENDS terms in a web-based smoking cessation intervention; and (2) determine whether terms vary by US geographic region and date. METHODS: Data were drawn from public posts between 2008-2015 on and limited to US users...

INTRODUCTION: Electronic cigarette (EC) use is proliferating, but initial uptake patterns and their influence on smoking remains unclear. This study of EC sampling examines naturalistic uptake of ECs, as well as effects on smoking and perceived reward from smoking and vaping. METHODS: Within a double-blind randomized crossover design, smokers (n = 24; 75% male; M age = 48.5 years) smoked as usual for 1 week, followed by two counterbalanced naturalistic (ie, ad libitum use) weeks of either placebo or active first generation ECs...

BACKGROUND: Although most US states prohibit cigarette smoking in public places and worksites, fewer jurisdictions regulate indoor use of electronic cigarettes (e-cigarettes). Given the dramatic increase in e-cigarette use and concern about its impact on non-users, there is a need to examine the use of e-cigarettes in smoke-free environments and related attitudes and perceptions. METHODS: Recruited from a nationally representative adult panel (GfK's KnowledgePanel), 952 current users of e-cigarettes completed a cross-sectional online survey in 2014...
