I wake up and hit the JUUL: Analyzing Twitter for JUUL nicotine effects and dependence.

JUUL-a novel electronic nicotine delivery system (ENDS)-comprises most of the ENDS market share. Additionally, JUUL has a high nicotine content and utilizes a patented nicotine salt formulation aimed to speed absorption. Many JUUL users are not aware of the nicotine content and therefore may not be expecting acute nicotine effects or potential for dependence. This study sought to analyze Twitter messages ("tweets") regarding nicotine, symptoms of dependence, and withdrawal related to JUUL use.

Adolescents' awareness of the nicotine strength and e-cigarette status of JUUL e-cigarettes.

JUUL e-cigarettes are popular among youth. However, it is unknown whether adolescents understand that 5% JUUL pods contain a high nicotine concentration or consider JUULs to be e-cigarettes.

JUUL in school: JUUL electronic cigarette use patterns, reasons for use, and social normative perceptions among college student ever users.

JUUL electronic cigarettes have surged in popularity since their emergence on the market in 2015. JUUL is slim and simple in design and is capable of delivering cigarette-like levels of nicotine.

Effects of nicotine and THC vapor inhalation administered by an electronic nicotine delivery system (ENDS) in male rats.

Electronic nicotine delivery systems (ENDS, e-cigarettes) are increasingly used for the self-administration of nicotine by various human populations, including previously nonsmoking adolescents. Studies in preclinical models are necessary to evaluate health impacts of ENDS including the development of nicotine addiction, effects of ENDS vehicles, flavorants and co-administered psychoactive substances such as Δ-tetrahydrocannabinol (THC). This study was conducted to validate a rat model useful for the study...

Sociodemographic Correlates of Electronic Nicotine Delivery Systems (ENDS) Use in the United States, 2016-2017.

To investigate use of electronic nicotine delivery systems (ENDS) among priority populations. Using 2016 through 2017 US nationally representative surveys (n = 11 688), we examined ENDS use by sociodemographic variables (age, education, poverty status, insurance, employment, race/ethnicity, sexual orientation) and combustible tobacco use. Among individuals who currently use noncigarette combustible tobacco, those from certain backgrounds (young adults, those living below the poverty level, those les...

Modeling Drug Exposure in Rodents using e-Cigarettes and other Electronic Nicotine Delivery Systems.

Smoking tobacco products is the leading cause of preventable death worldwide. Coordinated efforts have successfully reduced tobacco cigarette smoking in the United States; however, electronic cigarettes (e-cigarette) and other electronic nicotine delivery systems (ENDS) recently have replaced traditional cigarettes for many users. While the clinical risks associated with long-term ENDS use remain unclear, advancements in preclinical rodent models will enhance our understanding of their overall health effect...

High Nicotine Electronic Cigarette Products: Toxicity of JUUL Fluids and Aerosols Correlates Strongly with Nicotine and Some Flavor Chemical Concentrations.

While JUUL electronic cigarettes (ECs) have captured the majority of the EC market with a large fraction of their sales going to adolescents, little is known about their cytotoxicity and potential effects on health. The purpose of this study was to determine flavor chemical and nicotine concentrations in the eight currently marketed pre-filled JUUL EC cartridges ("pods") and to evaluate the cytotoxicity of the different variants (e.g., "Cool Mint" and "Crème Brulee") using in vitro assays. Nicotine and fla...

Cue salience of the use of an electronic nicotine delivery system (ENDS) device marketed to women.

Passive exposure to the use of electronic nicotine delivery systems (ENDS or e-cigarettes) has been shown to generalize as a smoking cue. As young adult women in particular are increasingly targeted by ENDS distributors, the present study examined whether passive exposure to the use of a female-marketed ENDS product selectively enhanced smoking urge, cigarette and e-cigarette desire, and smoking behavior among women (vs men) smokers.

US Adult Smokers' Perceived Risk of Fire or Explosion-Related Injury Caused by Electronic Nicotine Delivery Systems.

Publicity on incidents of electronic nicotine delivery systems (ENDS) exploding or catching fire may influence smokers' risk perceptions and decisions about using ENDS for quitting smoking. We examined combustible cigarette smokers' perceptions of the possibility of injury from exploding ENDS and the relationship of those perceptions to ENDS use, perceived risk relative to smoking, and perceived costs and benefits of ENDS use.

Inclusion of electronic nicotine delivery systems in indoor smoke-free air policies and associated vaping behavior.

Despite an ongoing debate over regulations of use of electronic nicotine delivery systems (ENDS) in public places, fourteen U.S. states or territories banned use of ENDS in indoor areas such as workplaces, restaurants, or bars (aerosol-free policies), as of March 31 ,2018. However, there is a paucity of studies on state-level aerosol-free policies. This study aimed to investigate the relationship between statewide aerosol-free policies and U.S. adults' ENDS use.

Electronic cigarettes disrupt lung lipid homeostasis and innate immunity independent of nicotine.

Electronic nicotine delivery systems (ENDS) or e-cigarettes have emerged as a popular recreational tool among adolescents and adults. Although the use of ENDS is often promoted as a safer alternative to conventional cigarettes, few comprehensive studies have assessed the long-term effects of vaporized nicotine and its associated solvents, propylene glycol (PG) and vegetable glycerin (VG). Here, we show that compared with smoke exposure, mice receiving ENDS vapor for 4 months failed to develop pulmonary infl...

Developmental toxicity of e-cigarette aerosols.

Maternal smoking during pregnancy represents a major public health concern increasing the risk for low birth weight, congenital anomalies, preterm birth, fetal mortality, and morbidity. In an effort to diminish adverse developmental effects of exposure to cigarette smoking, pregnant women, and women of reproductive age, are increasingly turning to electronic nicotine delivery systems (ENDS), such as e-cigarettes, as an alternative. Given that health risks associated with ENDS use during pregnancy are largel...

A prospective longitudinal relation between elevated use of electronic devices and use of electronic nicotine delivery systems.

In recent years, there has been a rapid increase in the use of both electronic nicotine delivery systems (ENDS) and electronic devices among U.S. youth. Informed by the Diffusion of Innovations Theory (DIT), it was hypothesized that elevated use of electronic devices (EUED) prospectively would predict ENDS use among youth.

Correlates of cigarette and alternative tobacco product use among young tobacco users experiencing homelessness.

Most young people experiencing homelessness smoke cigarettes, but little is known about use of alternative tobacco products (ATPs) such as e-cigarettes or other electronic nicotine delivery systems (ENDS) and little cigars/cigarillos (LCCs). This study examines past month use and correlates of cigarettes and ATP among young tobacco users experiencing homelessness.

The rise of e-cigarettes, pod mod devices, and JUUL among youth: Factors influencing use, health implications, and downstream effects.

Electronic cigarettes (e-cigarettes) were first introduced in the U.S. market in 2006, with the more recent evolution of "pod-mod" e-cigarettes such as JUUL introduced in 2015. Although marketed as a smoking cessation tool, e-cigarettes are rarely used for this purpose in youth. This review aims to synthesize the literature regarding e-cigarette use among youth, and provides a resource for clinicians, educators, and families that helps answer commonly asked questions about e-cigarettes.

Nicotine self-administration with tobacco flavor additives in male rats.

Nicotine can robustly increase responding for conditioned reinforcers (CRs), stimuli that acquire reinforcing properties based on association with primary reinforcers. Menthol and licorice are tobacco flavoring agents also found in sweet foods (e.g., candy, ice cream), making them putative CRs before they are consumed in tobacco. We sought to determine if intravenous self-administration (IVSA) of nicotine was enhanced by the inclusion of oral tobacco flavor CRs.

Less burn, more fat: electronic cigarettes and pulmonary lipid homeostasis.

Electronic nicotine delivery systems (ENDS) are rapidly increasing in popularity due to the perception that they may represent a safe alternative to conventional cigarettes. However, a growing body of evidence indicates that ENDS exposure can disrupt maintenance of pulmonary immune homeostasis and antimicrobial immunity. In this issue of the JCI, Madison et al. demonstrate that in mice, chronic ENDS exposure induces profound alterations in lipid homeostasis. ENDS-exposed mice showed irregularities in the su...

Why flavored vape products may be attractive: Green apple tobacco flavor elicits reward-related behavior, upregulates nAChRs on VTA dopamine neurons, and alters midbrain dopamine and GABA neuron function.

While nicotine is the primary addictive component in tobacco products, additional flavors have become a concern with the growing popularity of electronic nicotine delivery systems (ENDS). For this reason, we have begun to investigate popular tobacco and ENDS flavors. Here, we examined farnesol, a chemical flavorant used in green apple and fruit flavors in ENDS e-liquids, for its ability to produce reward-related behavior. Using male and female 3-6 month old C57BL/6 J mice and farnesol doses of 0.1, 1, and ...

Age differences in electronic nicotine delivery systems (ENDS) usage motivations and behaviors, perceived health benefit, and intention to quit.

Data from comprehensive studies are sparse regarding age differences in issues related to electronic nicotine delivery systems (ENDS) usage. This study examined age differences in usage motivations and behaviors, perceived health benefit, and quit intentions in a large and diverse sample recruited online.

Relationship between nicotine intake and reward function in rats with intermittent short versus long access to nicotine.

Tobacco use improves mood states and smoking cessation leads to anhedonia, which contributes to relapse. Animal studies have shown that noncontingent nicotine administration enhances brain reward function and leads to dependence. However, little is known about the effects of nicotine self-administration on the state of the reward system.

Potential Adverse Health Consequences From Use of E-Cigarettes and Vaping.

Smokers who use combustible tobacco products, such as cigarettes, cigars, and pipes, have been turning to electronic cigarettes (e-cigarettes) or electronic nicotine delivery systems (ENDS) as an alternative to combustible tobacco products and as a smoking cessation tool. Use of e-cigarettes has been referred to as vaping, with numerous terms for these devices, such as vaporizers, vape pens, hookah pens, e-cigs, or e-pipes.
