Introduction to Electronic Cigarettes

Although increased public awareness of the harms of cigarette smoking has successfully led to a decline in its prevalence, the use of electronic cigarettes (e‐cig) or electronic nicotine delivery system has increased dramatically in recent years because of the perception that these products are safe.

Electronic cigarettes (also known as e-cigarettes or electronic nicotine delivery systems) were invented in China in 2003 then introduced to the British market in 2007.

The objective of this study was the identification of biomarkers and biomarker patterns in body fluids, to distinguish between combustibles, heated tobacco products, electronic cigarettes, oral tobacco and oral/dermal nicotine products used for nicotine replacement therapy (NRT), as well as a control group of non-users.

Telephone surveys were used to collect information about smoking status and smoking/cessation history, use of smoking cessation programs and aids (prescription medications, nicotine replacement therapy, electronic cigarettes), motivation and intention to quit, self-efficacy (to quit), smoking cessation outcome expectancies, physician support to quit, barriers and facilitators for those who had not quit, and reinforcements/challenges for those who had quit.

As electronic cigarettes (e-cigarettes) become increasingly popular smoking devices, there is an increased risk for unintended exposure to e-cigarette liquids through improper disposal resulting in leaching into the environment, third hand vapor exposure through air, or embryonic exposure through maternal vaping.

Novel nicotine products, particularly electronic cigarettes (e-cigarettes), have become increasingly popular over the past decade.

Electronic cigarettes (e-cigarettes) have been touted as a safer alternative to cigarettes and even as a smoking cessation aid.

BACKGROUND Electronic cigarettes (e-cigarettes) are being marketed to smokers as a smoking cessation aid.

INTRODUCTION Electronic cigarettes (e-cigs) have increased in popularity as a potentially less harmful alternative to tobacco smoking; however, the literature suggests "vaping" can cause endothelial damage, which can adversely affect erectile function.

ABSTRACT Heated tobacco products (HTPs) and electronic cigarettes (ECs) represent a potentially less harmful alternative to traditional tobacco products, such as conventional cigarettes (CCs), with growing popularity amongst adult smokers worldwide.

E-cigarette or vaping use-associated lung injury (EVALI) was identified with the incidents of a multi-state outbreak of acute lung injuries associated with the use of electronic cigarettes (e-cigs) and attributed to vitamin E acetate in off-market cannabis-based e-liquids.

Electronic cigarettes seem capable of causing various injury patterns in the lungs, collectively called E-cigarettes or vaping-associated lung injury (EVALI).

The widespread use of electronic cigarettes (e-cig) is a serious public health concern; however, mechanisms by which e-cig impair the function of airway epithelial cells—the direct target of e-cig smoke—are not fully understood.

The use of electronic cigarettes (e-cigarettes) by adolescents is a serious public health concern.

Electronic cigarettes (ECIG) and heated tobacco products (HTP) are marketed as less harmful alternatives to CS.

Background Electronic cigarettes have been a popular alternative to tobacco smoking.

Background Electronic cigarettes (e-cigarettes) are relatively new tobacco products that are attracting public attention due to their unique features, especially their many flavor options and their potential as an alternative to cigarettes.

, millions of adults use electronic cigarettes (e-cigs), and a majority of these users are former or current cigarette smokers.

INTRODUCTION Most adults who use electronic cigarettes (ECs) also smoke combustible cigarettes (CCs).

Stealth vaping (ie, the use of devices resembling everyday products to facilitate inconspicuous vaping) has proliferated in the face of smokefree air laws that include electronic cigarettes (ecigarettes).

The tobacco product landscape has diversified to include electronic cigarettes (e-cigarettes).

Rationale: Smoking electronic cigarettes (e-cigarettes) is increasing in popularity, but there is little information available as to the biologic consequences to the cell populations impacted by the e-cigarette smoke.

Health risks associated with smoking electronic cigarettes and vape cigarettes by adolescents are described, and the correlation between smoking electronic cigarettes by adolescents and the use of other psychoactive substances is noted.

Electronic cigarettes may be a useful help to quit smoking in some patients.

(2) These findings warrant additional investigation to determine whether switching to electronic cigarettes may be an effective harm reduction strategy in smokers addicted to nicotine who are unable or unwilling to quit.

The use of electronic cigarettes among the young adult and adolescent population has increased over the past decade.

In order to inform prevention efforts, the present study examined the role of susceptibility measures as well as psychosocial, behavioral, and environmental factors in prospectively predicting ever use of electronic cigarettes among adolescents.
