Book Description
Millions of Americans use e-cigarettes. Despite their popularity, little is known about their health effects. Some suggest that e-cigarettes likely confer lower risk compared to combustible tobacco cigarettes, because they do not expose users to toxicants produced through combustion. Proponents of e-cigarette use also tout the potential benefits of e-cigarettes as devices that could help combustible tobacco cigarette smokers to quit and thereby reduce tobacco-related health risks. Others are concerned about the exposure to potentially toxic substances contained in e-cigarette emissions, especially in individuals who have never used tobacco products such as youth and young adults. Given their relatively recent introduction, there has been little time for a scientific body of evidence to develop on the health effects of e-cigarettes. Public Health Consequences of E-Cigarettes reviews and critically assesses the state of the emerging evidence about e-cigarettes and health. This report makes recommendations for the improvement of this research and highlights gaps that are a priority for future research.

Book Description
This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.

Book Description
Introduction: The use of electronic cigarettes (ECs) is controversial. Among the issues of concern is safety: some people think ECs are safer alternatives to conventional cigarettes (CCs), while others are concerned about the possible health effects of using ECs. Although many studies have identified hazards in EC emissions, there is only limited information about exposure levels and the likely health risks of using ECs. Methods: This study aimed to characterise the health risks of using ECs and compare them with the risks of using CCs by utilizing the U.S. EPA health risk assessment model. Hazards were identified and profiled (toxicological and exposure) using document review. The risk from exposure to hazards was thus identified and the overall health risks of using ECs and CCs were compared, and then benchmarked with international guideline levels for each hazard to evaluate whether the detected hazards might pose a significant health risk to users or not, given comparable exposures. Results: Exposures to toxicants of concern identified in EC emissions (acetaldehyde, acrolein, formaldehyde, diethylene glycol, propylene glycol, cadmium, nickel, NNK, and NNN) are almost all far lower than in CC emissions, indicating EC use under standard use conditions is likely to be far safer than smoking. As most hazards’ exposure levels in EC emissions are lower than the defined guideline levels, ECs are also likely to be of low risk to health. Conclusions & Recommendations: The health risks of using ECs are lower than CCs. In a few studies of some ECs, some toxicant levels exceeded levels regarded as safe by international standards. However, studies of ECs lack standardisation in the assessment methods for EC product performance, usage patterns and exposure. Future studies should adhere to a standard methodology to enable ready comparisons. Regulation of EC manufacture and sales is needed to prevent the sale of low quality ECs. Lastly, health professionals and the general public need more information on ECs as safer alternatives to cigarette smoking.

Book Description
This eighth report of the Study Group addresses electronic nicotine delivery system (ENDS), electronic non-nicotine delivery system (ENNDS) and heated tobacco product (HTPs); however, it does not cover all aspects of these products, because many of the papers were written to meet the request of COP8, which was to review understanding on novel and emerging tobacco products (FCTC/COP8). Continued research is necessary on these products; the Study Group will cover other products of interest (including traditional products, such as waterpipes, cigarettes and smokeless tobacco) in its next report, guided by countries’ regulatory requirements and pertinent issues in tobacco product regulation. This will ensure continued, timely technical support to all countries and address all products, recognizing that their availability depends on the jurisdiction.

Book Description
A volume in the Emerging Issues in Analytical Chemistry series, Analytical Assessment of E-Cigarettes: From Contents to Chemical and Particle Exposure Profiles addresses the many issues surrounding electronic cigarettes in an unprecedented level of scientific detail. The plethora of product devices, formulations, and flavors, combined with the lack of industry standards and labeling requirements, quality control, and limited product oversight, has given rise to public concern about initiation of use and potential for adverse exposure and negative long-term health outcomes. This volume discusses how analytical methods can address these issues and support the manufacturing, labeling, distribution, testing, regulation, and monitoring for consistency of products with known chemical content and demonstrated performance characteristics. The book begins with the background on aerosol drug delivery services and e-cigarettes, constituents of nicotine-containing liquid dosing formulations, typical use scenarios and associated aerosol emissions, and chemical exposures and pharmacological and toxicological effect profiles, and then continues with descriptions of the analytical methods used to characterize the chemicals in formulations and emissions from e-cigarettes, including their stability, physical particle-size distribution and thermal degradation under commonly employed conditions of use. Analytical methods enabling detection of biomarkers of exposure and harm in complex biological matrices are discussed, with an emphasis on constituents or emissions of current medicinal interest or with potential to produce harm. Opportunities and challenges for analytical chemistry in supporting the continued development and use of safe and consistent dosage formulations as alternatives to tobacco products are also explored, with a concluding section describing an analytical approach to a risk-benefit assessment of e-cigarette use on human health. The Emerging Issues in Analytical Chemistry series is published in partnership with RTI International and edited by Brian F. Thomas.

Book Description
This report makes available the findings of an international group of experts that provide WHO with the latest scientific and technical advice in the area of product regulation. The third report presents the conclusions reached and recommendations made by the members of the WHO Study Group on Tobacco Product Regulation at its fifth meeting, during which it reviewed two background papers specially commissioned for the meeting and which dealt, respectively, with the following two themes: devices designed for the purpose of nicotine delivery to the respiratory system in which tobacco is not necessary for their operation and setting regulatory limits for carcinogens in smokeless tobacco. The Study Group's recommendations in relation to each theme are set out at the end of the section dealing with that theme. Its overall recommendations are summarized in section 4. The Study Group intends this new set of recommendations to be useful to WHO Member States and national policymakers and regulators in shaping tobacco control policy.
