The electronic cigarette is an electronic device created with the aim of providing an alternative to the consumption of processed tobaccos that traces the mimics and sensory perceptions of the latter. E-cigarettes are often sold as alternatives to tobacco smoke that are considered less harmful to health, as the carcinogenic components found in traditional smoke are absent.
Another target market is represented by subjects who intend to quit smoking. However, the World Health Organization in November 2010 stated that there are currently no studies on the effectiveness of this measure, and recommends organizing further in-depth studies on the subject.
The production and trade of electronic cigarettes is managed by the tobacco industry. The study: Health effects of electronic cigarette (e ‑ cigarette) use on organ systems and its implications for public health, published on the Wiener klinische Wochenschrift, explained: "here has been growing concern over the use of electronic cigarettes (e-cigarettes) in recent years.
Although advocated as an aid to smoking cessation, there is increasing evidence of harm not just to the respiratory system, but to all other organs in the body. To give a clearer picture on how e ‑ cigarettes can affect our health, we gathered an overview of the literature on the various health effects of e ‑ cigarettes and categorized them into how they specifically affect organ systems.
E ‑ cigarette exposure has produced a range of stress and inflammatory reactions in the pulmonary system, including shortness of breath, coughing, wheezing, bronchial and pulmonary irritations, and impaired pulmonary function.
In the oral and gastrointestinal system, gingival inflammation, sore throat, nausea, vomiting, and d iarrhea have been reported. Increased tachycardia and blood pressure were reported reactions in the cardiovascular system.
In the neurological system headaches, irritability, anxiety, dependence and insomnia were observed. Other effects included ocular irritation, contact dermatitis, acute renal insufficiency, toxicity and potential carcinogenicity.
Nevertheless, studies have found improvements in time-based memory and nicotine withdrawal associated with the cessation of conventional cigarette smoking and switching to e ‑ cigarette use. Also, toxic and carcinogenic metabolites were reportedly lower in e ‑ cigarette smokers than in conventional cigarette smokers.
A growing number of studies are showing the adverse effects caused by e ‑ cigarettes on all human organ systems. Further research on the chemical components, the diverse flavors, and the long-term effects on active and passive users are needed to clarify the implications of e ‑ cigarette use on individual and public health.
