New Study Links E-Cigarette Use to Increased Risk of COPD and Hypertension

A large-scale study led by Johns Hopkins Medicine has revealed that exclusive use of e-cigarettes is significantly associated with an increased risk of chronic obstructive pulmonary disease (COPD), and may also be linked to a slight rise in high blood pressure among adults aged 30 to 70. The analysis, published in Nicotine & Tobacco Research used medical data from nearly 250,000 individuals over four years, providing one of the most comprehensive examinations to date of vaping’s long-term health impacts.
The study analyzed health outcomes across several tobacco use groups: exclusive e-cigarette users, exclusive combustible cigarette users, dual users, and non-users. Of the 249,190 participants, 3,164 were exclusive e-cigarette users, while over 33,000 used only combustible cigarettes. During the follow-up period, researchers documented over 23,000 new cases of hypertension, more than 13,000 new cases of type 2 diabetes, and nearly 8,000 new cases of COPD. Exclusive e-cigarette use was found to be significantly associated with the development of COPD, and in a specific sub-group aged 30–70, with a slight increase in hypertension risk. However, it was not significantly linked to heart failure, atherosclerotic cardiovascular disease, or type 2 diabetes.
