BackgroundElectronic cigarettes (ECs) are battery-operated devices designed to vaporise nicotine, which may help smokers quitting or reducing their tobacco consumption. There is a lack of data on the health effects of EC use among smokers with COPD and whether regular use results in improvement in subjective and objective COPD outcomes.We investigated long-term changes in objective and subjective respiratory outcomes in smokers with a diagnosis of COPD who quit or reduced substantially their… 

E-cigarettes in patients with COPD: current perspectives

TLDR
The use of ECs in vulnerable groups and in patients with challenges to abstain or multiple relapses to this habit may be promising, and little is known about health consequences of EC use among COPD smokers and whether their regular use has any effects on subjective and objective COPD outcomes.

COPD smokers who switched to e-cigarettes: health outcomes at 5-year follow up

TLDR
It is suggested that EC use for abstinence and smoking reduction may ameliorate some of the harm resulting from tobacco smoking in COPD patients and that the benefits gained appear to persist long term.

Health effects in COPD smokers who switch to electronic cigarettes: a retrospective-prospective 3-year follow-up

TLDR
It is suggested that EC use may ameliorate objective and subjective COPD outcomes and that the benefits gained may persist long-term, and may reverse some of the harm resulting from tobacco smoking in COPD patients.

Electronic cigarettes as a harm reduction strategy among patients with COPD: protocol for an open-label two arm randomized controlled pilot trial

TLDR
The purpose of this pilot study is to identify barriers and facilitators to the use of and assess the preliminary effectiveness of EC as a harm reduction strategy among people with COPD, which has the potential to significantly improve the health of people with CopD who smoke.

Health outcomes in COPD smokers using heated tobacco products: a 3-year follow-up

TLDR
This study is the first to describe the long-term health effects of HTP use in COPD patients and consistent improvements in respiratory symptoms, exercise tolerance, quality of life, and rate of disease exacerbations were observed in patients with COPD who abstained from smoking or substantially reduced their cigarette consumption by switching to HTPs.

How safe are e-cigarettes for patients with COPD? A systematic review

TLDR
Findings support current clinical guidance endorsing the use of e-cigarettes for smoking cessation; however, COPD patients may be at greater risk of inflammatory responses, exacerbation, disease progression and worsening general health.

E-cigarettes and Smoking Cessation: Economic Impact on Current Smokers with Chronic Obstructive Pulmonary Disease

TLDR
To estimate the prevalence and study sociodemographic predictors for e-cigs use among individuals with Chronic Obstructive Pulmonary Disease (COPD), and to examine the predictors and estimate the total healthcare costs among current smokers with COPD.

Electronic cigarettes for smoking cessation.

TLDR
The safety and effect of using ECs to help people who smoke achieve long-term smoking abstinence and the main outcome measure was abstinence from smoking after at least six months follow-up is evaluated.

E-cigarettes and Smoking Cessation in Smokers With Chronic Conditions.

Adult E-Cigarettes Use Associated with a Self-Reported Diagnosis of COPD

TLDR
E-cigarette use was associated with a reported diagnosis of COPD among adults in the US, and the nature of this association and on the long-term effects of using e-cigarettes is still unclear.

Effect of Smoking Abstinence and Reduction in Asthmatic Smokers Switching to Electronic Cigarettes: Evidence for Harm Reversal

TLDR
It is indicated that regular use of e-cigs to substitute smoking is associated with objective and subjective improvements in asthma outcomes, and shows that e-Cigs can be a valid option for asthmatic patients who cannot quit smoking by other methods.

Effectiveness and tolerability of electronic cigarette in real-life: a 24-month prospective observational study

TLDR
Long-term e-Cigarette use can substantially decrease cigarette consumption in smokers not willing to quit and is well tolerated.

The Effects of Smoking Cessation on the Risk of Chronic Obstructive Pulmonary Disease Exacerbations

TLDR
Ex-smokers in a cohort study of 23,971 veterans who were current and past smokers and had been seen in one of seven Department of Veterans Affairs primary care clinics had a significantly reduced risk of COPD exacerbations, and the described reduction is dependent upon the duration of abstinence.

Respiratory infections and pneumonia: potential benefits of switching from smoking to vaping

TLDR
In conclusion, smokers who quit by switching to regular ECs use can reduce risk and reverse harm from tobacco smoking and innovation in the e-vapour category is likely not only to further minimise residual health risks, but also to maximise health benefits.

Risk of hospital admission for COPD following smoking cessation and reduction: a Danish population study

TLDR
Self-reported smoking cessation is associated with a reduction in the risk of COPD morbidity of approximately 40%; the benefit of smoking reduction is questionable.

TLDR
The focus of this article is on the health effects of using an E-cig, with consideration given to the acceptability, safety and effectiveness of this product as a long-term substitute for smoking.
