Vaping e-cigarettes differs from smoking traditional cigarettes in several key ways:

1. Method of Delivery: Traditional cigarettes involve burning tobacco and inhaling the smoke. In contrast, e-cigarettes use a battery-powered device to heat a liquid (often containing nicotine), which is then inhaled as an aerosol or vapor.

2. Chemical Composition: Cigarette smoke contains over 7,000 chemicals, many of which are toxic and can cause cancer. E-cigarettes have a different chemical composition, typically involving fewer toxic substances. However, they still contain potentially harmful chemicals, especially in flavorings.

3. Health Risks: While both traditional cigarettes and e-cigarettes pose health risks, the specific risks differ. Cigarette smoking is well-known for causing lung cancer, heart disease, and other serious conditions. E-cigarettes are relatively newer, so long-term studies are still ongoing, but they are generally considered less harmful than traditional cigarettes. However, they are not risk-free and have been linked to lung injuries and cardiovascular issues.

4. Nicotine Content: Both cigarettes and e-cigarettes often contain nicotine, a highly addictive substance. However, the amount of nicotine can vary widely in e-cigarettes, and some e-liquids may have no nicotine at all.

5. Physical Sensation: Some users report differences in the "throat hit" or the sensation experienced in the throat when inhaling. This sensation tends to be harsher with traditional cigarettes due to the combustion process.

6. Flavors: E-cigarettes come in a variety of flavors, which is not the case with traditional cigarettes. This variety can be appealing to some users, especially younger ones, which raises concerns about youth vaping.

7. Secondhand Exposure: Secondhand smoke from cigarettes is known to be harmful to bystanders. While e-cigarettes also produce an aerosol that can be inhaled by others, the overall health impacts of secondhand exposure to e-cigarette vapor are not as well understood but are considered to be less harmful than traditional cigarette smoke.

8. Environmental Impact: Traditional cigarettes contribute to litter and pollution through cigarette butts, which are one of the most common forms of litter. E-cigarettes, on the other hand, involve plastic and electronic waste.
