Andrew Hill, Oscar M Camacho
In 2012 the US FDA suggested the use of mathematical models to assess the impact of releasing new nicotine or tobacco products on population health outcomes. A model based on system dynamics methodology was developed to project the potential effects of a new nicotine product at a population level. A model representing traditional smoking populations (never, current and former smokers) and calibrated using historical data was extended to a two-product model by including electronic cigarettes use statuses. Smoking mechanisms, such as product initiation, switching, transition to dual use, and cessation, were represented as flows between smoking statuses (stocks) and the potential effect of smoking renormalisation through a feedback system...

BACKGROUND: In May 2016, the Food and Drug Administration (FDA) issued a final rule that deemed e-cigarettes to be within their regulatory authority as a tobacco product. News and opinions about the regulation were shared on social media platforms, such as Twitter, which can play an important role in shaping the public's attitudes. We analysed information shared on Twitter for insights into initial public reactions. METHODS: A text mining approach was used to uncover important topics among reactions to the e-cigarette regulations on Twitter...

Introduction.: In recent years, e-cigarettes overtook cigarettes as the leading tobacco product used by U.S. adolescents. Most states, as well as federal regulations, have added e-cigarettes to laws prohibiting tobacco products sales to minors. We tested compliance with the newer regulation among Colorado urban retail businesses, speculating that violations might be more common for e-cigarettes than smokable cigarettes. Methods.: Supervised minors visited a random sample of urban businesses and sequentially attempted to purchase an e-cigarette product and cigarettes...

Electronic cigarettes (e-cigarettes) are increasing in popularity with 19% of UK smokers reporting to have used them. The ability to regulate the evaporation temperature in newer electronic nicotine delivery systems (ENDS) facilitates the potential for use of these devices to 'vape' cannabis, novel psychoactive substances (NPS) and other recreational drugs. Vaping cannabis does have the potential to reduce tobacco use and combustible cannabis/tobacco-related disease, but with over one-third of UK adults reporting life-time use of recreational drugs and increasing e-cigarette uptake in adolescent groups the misuse of these devices poses a serious potential public health risk...

Background Many smokers have recently turned to electronic cigarettes (e-cigarettes) because they have been marketed as a cheaper and safer smokeless alternative to traditional cigarettes, and a possible smoking cessation tool. Even though the safety of these electronic devices is still not fully known, there is evidence of their cytotoxicity on cells which belong to the oral cavity. In a previous paper the increase of reactive oxygen production and Bax expression, followed by the occurrence of apoptosis, were demonstrated in human gingival fibroblasts...

Recent studies suggest that electronic cigarette (e-cig) flavors can be harmful to lung tissue by imposing oxidative stress and inflammatory responses. The potential inflammatory response by lung epithelial cells and fibroblasts exposed to e-cig flavoring chemicals in addition to other risk-anticipated flavor enhancers inhaled by e-cig users is not known. The goal of this study was to evaluate the release of the proinflammatory cytokine (interleukin-8 [IL-8]) and epithelial barrier function in response to different e-cig flavoring chemicals identified in various e-cig e-liquid flavorings and vapors by chemical characterization using gas chromatography-mass spectrometry analysis...

Although a few countries have banned flavored cigarettes (except menthol), flavors in most tobacco products remain unregulated across the globe. We conducted a systematic review of qualitative studies examining perceptions of and experiences with flavored non-menthol tobacco products. Of 20 studies on flavored tobacco products included in our qualitative systematic review, 10 examined hookah, six examined e-cigarettes, two examined little cigars and cigarillos (LCCs), and three examined other tobacco products, including cigarettes...

Personal battery powered vaporizers or electronic cigarettes were developed as an alternative to traditional cigarettes. The modern electronic cigarettes were patented in 2004 by Hon Lik in China. In May 2016, the US Food and Drug Administration (FDA) imposed regulatory statutes on e-cigarettes and their liquid formulations (e-liquids); prior to that, they were unregulated. E-liquids are typically composed of propylene glycol and/or glycerin, flavoring component(s), and active ingredient(s), such as nicotine...

BACKGROUND: Recent data suggests that positive beliefs about electronic cigarettes (e-cigs) use can lead to later e-cig use. Considering that many advertisements claim that e-cigs are superior to cigarettes, individuals' likelihood to view e-cigs more favorably than cigarettes can also influence subsequent e-cig use; however, no studies have directly assessed such a comparison. OBJECTIVES: The present study created and validated the Comparing E-Cigarettes and Cigarettes questionnaire (CEAC), which asks individuals to directly compare e-cigs and cigarettes on a number of dimensions, in two independent samples...
