E-cigarettes aren’t as safe as you think, your blood vessels are still at risk: study
A new study shows that nicotine-free e-cigarettes also damage blood vessels, reducing blood flow and oxygen levels. Researchers observed immediate vascular effects in vapers and smokers, raising concerns about long-term risks. Studies show that it is best to quit smoking. Read on to know effective ways to quit smoking.

To quit smoking, we often look for alternatives that can control the withdrawal symptoms and help us achieve our goal of becoming smoke-free. But did you know that nicotine-free e-cigarettes can also have immediate adverse effects on blood vessels? Yes, you read that right. A recent study, led by Dr. Marianne Nabbout of the University of Arkansas for Medical Sciences at the University of Pennsylvania, challenges the perception of e-cigarettes as safe alternatives to traditional tobacco products.
The study included 31 healthy adults aged 21 to 49 who did not regularly drink alcohol or smoke. Participants underwent MRI scans twice: before and after using three types of products – a traditional tobacco cigarette, a nicotine-containing e-cigarette, and a nicotine-free e-cigarette. The researchers also studied a control group of 10 non-smokers and non-vapers aged 21 to 33 for comparison.
The researchers used phase-contrast MRI to examine blood flow in the femoral artery, which supplies oxygen-rich blood to the lower body, and assess oxygen levels in the veins. A thigh cuff was used to temporarily restrict blood flow, allowing measurement of the speed of blood flow and oxygen levels upon release.
The results showed that there was a significant reduction in blood flow and oxygenation in the femoral artery after exposure to all three types of products. Specifically, nicotine-containing e-cigarettes caused the largest decline, followed by nicotine-free e-cigarettes.
“If acute use of e-cigarettes can immediately affect blood vessels, long-term use can lead to vascular disease,” Dr. Nabbout said, explaining the potential long-term effects.
Health Risks of Vaping and Smoking
Both vaping and smoking contribute to reduced oxygen levels in the bloodstream which affects blood flow, which can increase the risk of heart diseases over time. Even without nicotine, e-cigarette aerosols contain harmful chemicals that can irritate and damage blood vessels. Therefore, it is essential to quit smoking as soon as possible. Here we have listed effective ways that can help you quit smoking and vaping.
How to Quit Vaping and Smoking
1. Practical Support:
-Join support groups or seek professional counseling to address triggers and develop coping strategies.
– Apps like QuitSure and Quit Genius provide tools to track progress and provide motivational content.
2. Nicotine Replacement Therapy (NRT):
– Use products such as nicotine gum, patches or lozenges to gradually reduce dependence.
3. Medicine:
– Consult a healthcare provider about prescription medications, such as bupropion or varenicline, that can stop cravings.
4. Mindfulness Practice:
-Engage in yoga, meditation or deep breathing exercises to control stress and reduce the urge to vape or smoke.
5. Lifestyle Changes:
– Regular physical activity improves mood and reduces cravings.
-Stay hydrated and eat a balanced diet to deal with withdrawal symptoms.
6. Set clear goals:
