What are electronic cigarettes?
Electronic cigarettes typically involve converting liquid into an aerosol, facilitated by a battery circuit. The liquid contents include nicotine, propylene glycol, flavoring agents, and other substances. Growing awareness and use of electronic cigarettes has been observed among the young and high-income groups, and popularity is growing through advertising ( Adkison and others 2013; Regan and others 2013 ). Electronic cigarettes do not fall under the ambit of regulatory authorities in most countries. Although some have advocated electronic cigarettes as a smoking cessation aid, many public health experts have spoken strongly against popularizing e-cigarettes. This is not only because of concerns about limited evidence of e-cigarettes’ aiding cessation; it is also because of evidence of e-cigarettes’ toxicity and of their potential to induce smoking in nonsmokers, especially youth, and to perpetuate nicotine addiction among users, thereby jeopardizing users’ attempts to quit smoking. The research on the chemical constituents and toxicity of e-cigarettes is growing. This toxicity is particularly concerning in people with CVD ( Benowitz and Burbank 2016 ). This and other reviews ( Morris and others 2015) document the many negative cardiovascular effects of e-cigarettes. Furthering the results of chemical and toxicological studies, preclinical research shows that compared with cigarettes, e-cigerettes also have detrimental effects on vascular function, specifically oxidative stress and endothelial function ( Carnevale and others 2016 ). Clinical studies of the chronic cardiovascular effects of e-cigarettes are forthcoming.
How many people died from CVD in 2013?
Tobacco is also the leading cause of premature death from CVD (deaths before age 70 years), accounting for an estimated 5.9 million premature deaths in 2013 ( Roth, Nguyen, and others 2015 ). Such deaths deprive families of productive members, and communities and economies of a productive workforce ( Rigotti and Clair 2013 ).
Where is bidi smoking practiced?
Bidi smoking is practiced in India and other countries in South Asia. Bidi smoking is more common among low-socioeconomic-status groups, raising equity issues related to its use and health effects. Tobacco is wrapped in leaves that are then thinly rolled and secured with threads. Bidi rolling is an unregulated business that includes households, small workshops, and cooperatives that evade regulations and taxes ( Gupta and Asma 2008 ). Bidis have concentrations of nicotine, tar, and other toxic ingredients equal to or greater than those in cigarettes. Given the increased risk of CVD at a young age among the Indian population, the adverse effects of this and other forms of tobacco use have large population-level health impacts. The INTERHEART study revealed that, in addition to cigarette smoking, use of other forms of tobacco such as bidi and chewing tobacco (also common in South Asian countries) was associated with a significantly higher risk of heart attack. The risk with bidi use was as high as the risk with cigarettes, but that of chewed tobacco was slightly lower. However, the risk was highest (fourfold compared with those who never smoked) in individuals who used both smoked and smokeless forms of tobacco ( Teo and others 2006 ). Another hospital-based case-control study confirmed nine times greater risk (RR 9.1, 95 percent CI 4.7–17.7) of myocardial infarction among those who smoked more than 10 bidis a day compared with nonsmokers; the risk was slightly less for persons smoking an equal number of cigarettes per day (RR 7.3, 95 percent CI 3.9–13.8) (Rastogi and others 2005).
What are the effects of toxic chemicals on the endothelium?
Toxic chemicals such as carbon monoxide, polycyclic aromatic hydrocarbons, nicotine, and heavy metals and their oxides have profound effects on vascular endothelium (cells lining the blood vessels), blood lipids (fats), and clotting (thrombotic) factors causing atherosclerosis (plaque buildup).
How much is the global mandate for reducing tobacco use?
The global mandate for reducing tobacco use is stronger than ever, with the World Health Assembly’s adoption of a 30 percent global target for relative reduction of tobacco use by 2025. This goal is one among several targets to reduce premature mortality from four noncommunicable diseases, including CVD, by 25 percent by 2025 (the 25×25 target). Unfortunately, many countries are not on course to meet this target ( Bilano and others 2015 ).
Does tobacco affect all countries?
Although tobacco use affects all countries regardless of their level of economic or health system development, the impact is most profound in low- and middle-income countries (LMICs), which shoulder the largest share of total and premature deaths from CVD globally ( WHO 2015a ).
