E-cigarettes are devices designed to deliver nicotine to users without burning tobacco. These are being marketed globally as a healthier substitute to the conventional cigarettes and as smoking quitting aids. The use of these devices has increased recently in developed countries with approximately 1.3 million users reported in the United Kingdom in 2013. Perception of these products as a safe alternative, appealing advertisements, and lax regulatory policies have helped gain popularity among the public. Despite all these claims, a debate is on-going because of insufficient scientific data regarding safety and efficacy of e-cigarettes as well as awareness of the potential health hazards. To solve the dilemma, more scientific studies in this field are required. Prompt regulatory response with strict vigilance on marketing and advertising may be desirable in the interest of users and public at large.

The COVID-19 pandemic has resulted in many survivors experiencing post-acute COVID-19 syndrome (PCS) with symptoms including fatigue, breathlessness, and cognitive complaints. E-cigarette use has already been associated with increased susceptibility to COVID-19 because of its effects on ACE2 receptor expression and inflammation, raising concern that it might worsen the long-term outcomes of COVID-19, including PCS. While traditional smoking is associated with a higher risk of PCS, the role of e-cigarettes remains unclear due to conflicting evidence.

Pregnancy is a vulnerable time with significant cardiovascular changes that can lead to adverse outcomes, which can extend into the postpartum window. Exposure to emissions from electronic cigarettes (Ecig), commonly known as "vaping," has an adverse impact on cardiovascular function during pregnancy and post-natal life of offspring, but the postpartum effects on maternal health are poorly understood. We used a Sprague Dawley rat model, where pregnant dams are exposed to Ecigs between gestational day (GD)2-GD21 to examine postpartum consequences.
