Nicotine-Free Vaping: A “Safer” Alternative? New Study Raises Alarming Concerns
You may have switched from traditional cigarettes to a vape, believing it was the healthier choice. However, a disturbing new study reveals that even nicotine-free vaping can have serious consequences for your vascular health, increasing the risk of heart disease and circulation problems.
While cigarettes are loaded with thousands of toxic substances like tar and carcinogens, vaping was often seen as a safer alternative. However, the idea that nicotine-free vapes are harmless is now being questioned.
If you’ve never smoked before, vaping—even without nicotine—can still present unnecessary health risks, according to recent findings.
Vaping vs. Smoking: What You Need to Know
E-cigarettes, or vapes, are battery-powered devices that heat liquid to produce vapor. Unlike traditional cigarettes, which burn tobacco and release harmful chemicals, vapes don’t create smoke or tar, leading many to believe they are a safer option. However, they come with their own risks.
The “vape juice” typically contains a mixture of propylene glycol and vegetable glycerin, both safe for ingestion but potentially harmful when inhaled. When these ingredients are heated, they can break down into substances that irritate the lungs and airways, leading to:
- Chronic coughing
- Difficulty breathing
- Lung inflammation
The Hidden Dangers of Flavors
Flavors like fruit, mint, and dessert varieties are a major draw for vapers, but many of these contain harmful chemicals, such as:
- Diacetyl: Linked to a severe lung condition called popcorn lung.
- Benzaldehyde: A flavoring agent that can irritate the respiratory system.
- Heavy metals: Vape coils can release lead, nickel, and tin into the vapor.
Even without nicotine, prolonged exposure to these substances can result in lung damage and inflammation.
“We don’t fully understand all the risks yet, but we know it’s not safe,” said Dr. Michael Blaha from Johns Hopkins Medicine.
The Growing Trend
Vaping is on the rise, with over 2 million U.S. middle and high school students reporting e-cigarette use in 2021, and more than 80% of these users opting for flavored products, according to Johns Hopkins.
Dr. Blaha expressed concern about the growing popularity of vaping, especially among young people who might never have smoked. “Switching from cigarettes to vaping is one thing, but starting nicotine use through vaping is a whole different issue. It can lead to addiction and potentially prompt experimentation with traditional tobacco products.”
What the Study Revealed
A 2024 study compared the effects of nicotine-free vapes, nicotine-containing vapes, and traditional cigarettes on blood vessel function. The results were surprising: all three types of smoking products showed significant negative effects on blood vessels, indicating that nicotine is not the only factor contributing to the dangers of vaping.
The study found that vascular function declined the most after using nicotine-containing e-cigarettes, followed by nicotine-free vapes.
Dr. Marianna Nabbout, one of the lead researchers, emphasized, “This study highlights how quickly smoking and vaping can impact the vascular systems in the human body. If using e-cigarettes causes noticeable changes in blood vessels right away, long-term use may lead to more severe vascular diseases.”
Time to Rethink Vaping?
If you’ve been using vaping as a safer alternative to smoking, this new research might make you think twice about its potential health risks.
