Researchers at the University of Alberta found evidence that nicotine vapes damage the heart and lungs of young people who have never smoked [1, 2].

This discovery challenges the perception that vaping is a harmless alternative to combustible tobacco for non-smokers. Because the damage appears in individuals with no prior history of smoking, the findings suggest that nicotine delivery systems may pose an independent and immediate risk to cardiovascular health.

The study focused on participants in their early 20s [2]. The researchers said that nicotine exposure from these devices leads to reduced blood flow in the lungs [2]. This physiological change is linked to early signs of cardiovascular impairment [2].

The research team based in Edmonton, Alberta, conducted the study to understand how vaping affects the respiratory and circulatory systems of a demographic that has not used traditional cigarettes [1, 2]. By isolating the effects of vaping from the long-term damage caused by smoking, the team was able to identify specific markers of heart and lung distress.

According to the findings, the impairment of blood flow in the lungs can lead to systemic issues within the heart [2]. This suggests that the damage occurs faster than previously understood for certain young users, creating a risk profile that differs from traditional tobacco use.

The University of Alberta report said young adults are vulnerable to these chemicals [1]. The study highlights a direct correlation between the use of nicotine vapes and the onset of early cardiovascular damage in a healthy, non-smoking population [2].

“Nicotine vapes damage the heart and lungs of young people who have never smoked.”

These findings indicate that vaping is not a neutral activity for non-smokers, but rather a catalyst for early-onset cardiovascular and pulmonary dysfunction. By demonstrating that heart and lung damage occurs in young adults without a history of smoking, the research suggests that the delivery mechanism and nicotine concentration in vapes may accelerate physiological decline faster than traditional cigarettes in some cases.
