Vaping has become a popular alternative to smoking, often promoted as a safer option. However, recent studies have raised serious concerns about the health risks of vaping, even when nicotine-free. A new study reveals that nicotine-free vapes can still harm vascular function and increase the risk of heart disease, making it essential for users to reconsider the health consequences of this habit.
What is Vaping and Why is It Popular?
Vaping involves using battery-powered e-cigarettes that heat a liquid (commonly known as vape juice or e-liquid) to produce an aerosol that users inhale. Unlike traditional cigarettes, which release harmful chemicals and tar from burning tobacco, vapes don’t produce smoke. This has led many to believe that vaping is a safer alternative.
Vape juice typically contains a mixture of propylene glycol and vegetable glycerin. While these ingredients are safe to consume, their effects when inhaled are a different matter. Heating these substances in the e-cigarette can break them down into harmful byproducts that may irritate the lungs and airways, leading to a range of health problems.

The Dangers of Nicotine-Free Vaping
While nicotine is a well-known cause of addiction and health problems in cigarette smokers, a new study suggests that even nicotine-free vaping can have serious consequences. Researchers compared the effects of nicotine-free vapes, nicotine-containing vapes, and traditional cigarettes on vascular function. Shockingly, all three were found to negatively impact blood vessel function, which is a key factor in heart disease and circulatory issues.
Key Findings:
- Vaping (with and without nicotine) can significantly decrease vascular function.
- Nicotine-free vapes showed a decrease in vascular function, though not as severe as nicotine-containing vapes.
- Traditional cigarettes caused the most damage to vascular health, but vaping, even without nicotine, is not without risks.
Dr. Marianna Nabbout, one of the researchers involved in the study, explained that both nicotine and the chemicals in vaping liquids can negatively affect blood vessels. This is especially concerning because even short-term exposure to these chemicals can cause long-term vascular issues, which may eventually lead to chronic conditions like heart disease.
The Health Risks Linked to Vaping Chemicals
The flavoring chemicals that make vaping so appealing are another cause for concern. Some of the chemicals used to create fruity, minty, or dessert-like flavors have been linked to serious health problems. For example:
- Diacetyl: A chemical linked to “popcorn lung,” a severe and irreversible lung disease.
- Benzaldehyde: A common flavoring agent that can irritate the respiratory system.
- Heavy metals: Vape coils may release small amounts of lead, nickel, and tin into the vapor.
Even without nicotine, inhaling these substances over time can cause lung inflammation, chronic coughing, and shortness of breath. As Dr. Michael Blaha from Johns Hopkins Medicine warns, “You’re exposing yourself to all kinds of chemicals that we don’t yet understand and that are probably not safe.”
Vaping and Its Impact on Youth
One of the most alarming trends is the increasing popularity of vaping among youth. In 2021, more than 2 million middle and high school students in the U.S. reported using e-cigarettes, with a significant number using flavored varieties. Dr. Blaha points out the dangers of introducing nicotine through vaping, saying, “It’s one thing if you convert from cigarette smoking to vaping, but it’s quite another thing to start nicotine use with vaping.”
This trend raises concerns about a new generation becoming addicted to nicotine, which could later lead to the use of traditional tobacco products. For young people, the risks of vaping extend far beyond the immediate health effects, as it may lay the groundwork for long-term addiction and health problems.
The Need for Awareness and Caution
Given the serious health risks associated with vaping, it’s crucial for both current and potential users to be aware of the dangers. The idea that nicotine-free vapes are safe has been debunked, with research showing that these products still pose significant health risks. The study highlights the importance of taking a closer look at the chemicals in e-cigarettes and understanding their potential impact on vascular health.
When to Seek Help
If you are concerned about the effects of vaping on your health or the health of someone you know, it is important to consult a healthcare provider. Particularly if you are experiencing any respiratory issues, chest pain, or discomfort after vaping, professional guidance can help you assess your risks and explore options for quitting. While quitting vaping can be challenging, it is the best way to prevent further harm to your lungs and overall health.
Conclusion: The Risks of Vaping are Real
In conclusion, nicotine-free vaping is not as harmless as it might seem. While it may be marketed as a safer alternative to smoking, it still carries significant health risks, particularly in terms of heart and lung function. The study’s findings are a wake-up call for those who believe that vaping without nicotine is risk-free. It’s time for everyone, especially young people, to reconsider their vaping habits and take the necessary steps to protect their health.
