Nicotine products have evolved from traditional cigarettes to vapes and nicotine pouches like Zyn, On!, and Velo. Many young adults assume newer options are safer. But when it comes to your heart, none are risk-free.
“There’s a common misconception that vaping or nicotine pouches are harmless,” says Sean P. Javaheri, MD, interventional cardiologist at Lexington Health Heart and Vascular Center. “The reality is that nicotine in any form stresses the cardiovascular system.”
Smoking: the highest overall risk
Traditional cigarettes remain the most dangerous for both heart and lung health. Smoking damages blood vessels, raises blood pressure, and accelerates plaque buildup in arteries. Over time, this greatly increases the risk of heart attack, stroke, and chronic heart disease.
“Smoking directly injures the lining of your blood vessels,” Dr. Javaheri explains. “That damage makes it easier for plaque to build up and harder for blood to flow normally, which can lead to serious cardiac events, even in younger adults.”
Vaping: not harmless to your heart
Vapes don’t produce smoke, but they still deliver nicotine and other harmful chemicals.
Nicotine from e-cigarettes can:
- Raise heart rate and blood pressure.
- Stiffen arteries, forcing the heart to work harder
- Trigger inflammation in blood vessels.
- Promote plaque buildup that can lead to a heart attack and stroke.
- Increase the risk of abnormal heart rhythms.
“Nicotine activates your body’s stress response,” says Dr. Javaheri. “That leads to higher blood pressure, a faster heart rate, and increased strain on the heart. Over time, those effects can contribute to long-term cardiovascular disease.”
Some vape devices deliver as much, or more, nicotine than cigarettes. Using both cigarettes and vapes further increases cardiovascular risk.
Nicotine pouches: smoke-free, but not risk-free
Nicotine pouches sit between the gum and lip and don’t involve smoke or vapor. While they may reduce lung exposure, the nicotine still affects the heart.
Nicotine pouches can:
- Increase heart rate and blood pressure.
- Narrow blood vessels.
- Increase strain on the heart.
- Lead to addiction, especially at higher doses.
“Just because there’s no smoke doesn’t mean there’s no risk,” Dr. Javaheri says. “Nicotine causes blood vessels to constrict and forces the heart to work harder. That can be especially concerning for people with existing heart conditions—or those developing risk factors at a young age.”
Nicotine replacement therapy is different
Nicotine gum, patches, and lozenges are FDA-approved tools designed to help people quit tobacco. They deliver controlled, lower doses of nicotine and are considered safe when used as directed.
Nicotine pouches, by contrast, are not approved quit-smoking treatments and often contain higher nicotine levels.
The bottom line for your heart
- Smoking: Highest risk for heart attack, stroke, and death
- Vaping: Still harms blood vessels and increases cardiac risk
- Nicotine pouches: Avoids smoke exposure, but still strains the cardiovascular system and is addictive
“The best thing you can do for your heart is avoid nicotine altogether,” Dr. Javaheri says. “If you’re trying to quit, talk with your doctor about proven, safer strategies that can help you stop for good.”
