An e-cigarette is a battery powered device used to generate atomized nicotine solutions, simulating the sensation of traditional cigarettes

It consists of a battery, heating elements, and liquid storage tanks

Users consume nicotine through the mist generated by smoking, without the need to burn tobacco, reducing the release of harmful substances and reducing the harm of secondhand smoke

Electronic cigarettes play a substitute role in quitting smoking and are considered healthier than traditional cigarettes, but potential risks and age restrictions still need to be noted

There is a significant difference in the composition between electronic cigarettes and regular cigarettes

Electronic cigarette ingredients:

1. Nicotine: The liquid in e-cigarettes usually contains nicotine, but its concentration can vary depending on the user's choice.

2. Plant glycerol/propylene glycol: a basic ingredient used to carry nicotine and produce atomization effects.

3. Flavor additives: In order to increase attractiveness and taste, electronic cigarette liquids may contain various flavor additives.

Ordinary cigarette ingredients：

1. Tobacco: The main component is tobacco leaves, which contain various harmful substances such as nicotine.

2. Tar: Harmful substances produced by burning tobacco, related to the respiratory system and health.

3. Carbon monoxide: a gas released during combustion that can affect the transportation of oxygen in the blood.

4. Benzene, heavy metals, etc.: other harmful chemicals generated during the combustion process.

Overall, compared to traditional cigarettes, electronic cigarettes have relatively simple components and do not contain harmful substances such as tar. However, the long-term health effects of e-cigarettes are still being studied, and their potential risks to the human body are not yet clear
