Background Paper on E-Cigarettes Article OVERALL SUMMARY While most discussion of e-cigarettes among health authorities has concentrated on the product itself, its potential toxicity and use of e-cigarettes to help people quit smoking, the e- cigarette companies have been rapidly expanding using aggressive marketing messages similar to those used to promote cigarettes in the 1950s and 1960s. Moreover, e-cigarette advertising is on television and radio in many countries that have long-banne…
Characterization of chemicals released to the environment by electronic cigarettes use (ClearStream-AIR project): is passive vaping a reality? Journal Article Background Electronic cigarettes (e-CIG) have been marketed as a safer alternative habit to tobacco smoking. We have developed a group of research protocols to evaluate the effects of e-CIG on human health, called ClearStream. No studies have adequately evaluated the effects of e-CIG use on the release of chemicals to the environment…
Cigarette Smoke Toxins Deposited on Surfaces: Implications for Human Health Journal Article Cigarette smoking remains a significant health threat for smokers and nonsmokers alike. Secondhand smoke (SHS) is intrinsically more toxic than directly inhaled smoke. Recently, a new threat has been discovered – Thirdhand smoke (
Comparison of the aerosol produced by electronic cigarettes with conventional cigarettes and the shisha Journal Article In previous studies of the smoke from regular cigarettes and water pipes, we measured aerosol particle sizes in three streams; S1, inhaled by the smoker, S2, released by the device itself and
Comparison of the effects of e-cigarette vapor and cigarette smoke on indoor air quality Journal Article CONTEXT: Electronic cigarettes (e-cigarettes) have earned considerable attention recently as an alternative to smoking tobacco, but uncertainties about their impact on health and indoor air quality have resulted in proposals for bans on indoor e-cigarette use. OBJECTIVE: To assess potential health impacts relating to the use of e-cigarettes, a series of studies were conducted using e-ci…
Critical Review of “Background Paper on E-Cigarettes” Prepared for the World Health Organization by Grana, Benowitz, and Glantz. Analytical Observation It has become apparent that many legislators and public health experts are relying on Background Paper On E-Cigarettes prepared for the World Health Organization by Rachel Grana, Neal Benowitz, and
Does e-cigarette consumption cause passive vaping? Journal Article Electronic cigarette consumption ('vaping') is marketed as an alternative to conventional tobacco smoking. Technically, a mixture of chemicals containing carrier liquids, flavors, and optionally nicotine is vaporized and inhaled. The present study aims at the determination of the release of volatile organic compounds (
Ecigarette mist harmless, inhaled or exhaled Report Background Electronic cigarettes, without tobacco, flame or smoke, claim to be cigarette substitutes and to deliver nicotine safely, without smoke toxicants. Are these claims justified? Aim
Exposure of the us population to environmental tobacco smoke: The third national health and nutrition examination survey, 1988 to 1991 Journal Article Objective.  To estimate the extent of exposure of the US population to environmental tobacco smoke and the contribution of the home and workplace environment to environmental tobacco smoke exposure.
Human Breath Emissions of VOCs Journal Article ABSTRACT The medical community has long recognized that humans exhale volatile organic compounds (VOCs). Several studies have quantified emissions of VOCs from human breath, with values ranging widely due to variation between and within individuals. The authors have measured human breath concentrations of isoprene and pentane.
Involuntary smoking in the restaurant workplace: A review of employee exposure and health effects Journal Article Objective.\\  To determine the relative exposure to environmental tobacco smoke for bar and restaurant employees compared with office employees and with nonsmokers exposed in the home (part 1) and to determine whether this exposure is contributing to an elevated lung cancer risk in these employees (part 2).
Letter re fatal flaws in Schober et al. paper on environmental vapor Blog Post by Carl V Phillips Below is a letter to the editor and Igor Burstyn and I will be submitting to the journal that published this article -- “Use of electronic cigarettes (e-cigarettes) impairs indoor air quality and increases FeNO levels of e-cigarette consumers” by Schober W, Szendrei K, Matzen W, Osiander-Fuchs H, Heitmann D, Schettgen T, Jörres RA, Fromme H – which made alarmist claims about the content of exh…
Levels of selected carcinogens and toxicants in vapour from electronic cigarettes Journal Article Significance Electronic cigarettes, also known as e-cigarettes, are devices designed to imitate regular cigarettes and deliver nicotine via inhalation without combusting tobacco. They are purported to deliver nicotine without other toxicants and to be a safer alternative to regular cigarettes. However, little toxicity testing has been performed to evaluate the chemical nature of vapour generat…
New Study of Passive Vaping Shows No Evidence of a Significant Public Health Hazard Blog Post A new study published online ahead of print in the International Journal of Hygiene and Environmental Health is one of the first to examine levels of chemicals in the ambient air of a real-life setting in the presence of electronic cigarette use.
New Study Shows that Thirdhand Smoke is 100 Times More Dilute than Secondhand Smoke Blog Post What may be the first investigation to actually measure the ambient levels of thirdhand smoke and compare them with levels of secondhand smoke, a new study
Peering through the Mist: Systematic Review of What the Chemistry of Contaminants in Electronic Cigarettes Tells Us about Health Risks Article-Journal Background Electronic cigarettes (e-cigarettes) are generally recognized as a safer alternative to combusted tobacco products, but there are conflicting claims about the degree to which these products warrant concern for the health of the vapers (e-cigarette users). This paper reviews available data on chemistry of aerosols and liquids of elec…
Real–Time Measurement of Outdoor Tobacco Smoke Particles Journal Article Abstract The current lack of empirical data on outdoor tobacco smoke (OTS) levels impedes OTS exposure and risk assessments. We sought to measure peak and time-averaged OTS concentrations in common outdoor settings near smokers and to explore the determinants of time-varying OTS levels, including the effects of source proximity and wind. Using five types of real-time airborne particle monitoring devices, we obtained mo…
The Bactericidal Action of Propylene Glycol Vapor on Microorganisms Suspended in Air II. the Influence of Various Factors on the Activity of the Vapor Journal Article A study of the conditions which affect the bactericidal action of propylene glycol vapor on air-suspended microorganisms has been carried out. The killing process was found to be more effective when both the total number of air-borne droplets and the number of organisms in the bacterial suspension are small. A temperature belo…
The Bactericidal Action of Propylene Glycol Vapor on Microorganisms Suspended in Air. I Journal Article It has been found that propylene glycol vapor dispersed into the air of an enclosed space produces a marked and rapid bactericidal effect on microorganisms introduced into such an atmosphere in droplet form. Concentrations of 1 gm. of propylene glycol vapor in two to four million cc. of air produced immediate and complete sterilization of air into which pneumococci, streptococci, staphylo…
THE MECHANISM OF AERIAL DISINFECTION BY GLYCOLS AND OTHER CHEMICAL AGENTS - 2 Journal Article The effectiveness of any compound as an aerial germicide depends upon the extent of condensation of its vapor on air-suspended bacteria, and on the rate at which the resulting concentration of germicide can produce death of the microorganisms. The properties of any compound conducive to production of the highest rate of kill of air-borne microorganisms by means of the smallest possible concentratio…
