The increase in perceived harm may reflect growing concerns about the teen vaping epidemic and the recent outbreak of vaping-related illnesses.
A two-year trial found that chronic smokers who transition to e-cigarettes demonstrated significant improvements in vascular health within four weeks. Women experienced greater gains by switching compared to men.
Scientists report that electronic cigarettes have adverse effects on the heart and blood vessels due to nicotine's impact on blood pressure and inflammation. The lack of standardised products makes it difficult to study the health effects of e-cigarettes, leading researchers to advise against their use.
