There are several potential benefits to switching from smoking to vaping.
Reduced exposure to harmful chemicals: Smoking cigarettes releases a wide variety of harmful chemicals, many of which are known to cause cancer. Vaping, on the other hand, generally involves inhaling vapor from a liquid that typically contains far fewer harmful chemicals than cigarette smoke.
Less exposure to secondhand smoke: Secondhand smoke from cigarettes can be harmful to those around the smoker. Vaping, however, generally produces little to no secondhand smoke, reducing the risk of exposure to others.
Lower risk of lung cancer: Lung cancer is the leading cause of cancer death in the world, and smoking cigarettes is the leading cause of lung cancer. While vaping is not risk-free, the risk of lung cancer is likely much lower for vapers than smokers.
Reduced risk of other smoking-related diseases: In addition to lung cancer, smoking cigarettes is also a major risk factor for a wide variety of other diseases, including heart disease, stroke, and chronic obstructive pulmonary disease (COPD). Switching to vaping may help reduce the risk of developing these diseases.
Cost savings: Over time, vaping can be less expensive than smoking, depending on how frequently and how much someone vapes.
