1. Respiratory Effects:  
   Vaping involves inhaling aerosolized substances, including nicotine, flavorings, and other chemicals. This can irritate the lungs and airways, sometimes leading to coughing, throat irritation, or shortness of breath. Some users have reported cases of lung injury linked to vaping (known as EVALI—e-cigarette or vaping product use-associated lung injury).

2. Nicotine Addiction and Effects:  
   Most vape liquids contain nicotine, a highly addictive substance. Nicotine can increase heart rate and blood pressure, may affect brain development in younger users, and contribute to dependency.

3. Chemical Exposure:  
   Although vaping lacks many harmful combustion byproducts found in cigarette smoke, it still exposes users to certain chemicals that could be toxic or carcinogenic in the long run.

4. Unknown Long-Term Effects:  
   Since vaping is relatively new, the long-term health consequences aren’t fully understood yet. Research is ongoing to determine potential chronic effects.

 Does Vaping “Hurt”?  
In the short term, some people experience throat or mouth irritation and coughing. Long term, vaping may contribute to respiratory and cardiovascular problems, especially with heavy use. It is generally considered less harmful than smoking traditional cigarettes, but it is not risk-free.

 Bottom Line  
If you don’t smoke, starting to vape may introduce unnecessary health risks. For smokers, vaping can be a harm-reduction tool if used to quit smoking, but quitting all nicotine products is best for your health.

If you have specific health concerns or want guidance on quitting smoking or vaping, consulting a healthcare professional can provide personalized advice.
