As the name implies, e-cigarette is also a kind of cigarette, but the substance it contains is different from our traditional tobacco. Then let's look at it separately:

? Traditional cigarettes: The smoke released by tobacco combustion contains more than 3,800 known chemical substances, most of which are harmful to human body, including alkaloids such as carbon monoxide and nicotine, amines, nitriles, drunkards, phenols, alkanes, aldehydes, nitrogen oxides, polycyclic aromatic hydrocarbons, heterocyclic compounds, hydroxyl compounds, heavy metal elements, organic pesticides and so on. , a wide variety, with a variety of biological functions, causing harm to the human body.

The content of nicotine in cigarettes varies with the quality of tobacco leaves and processing technology. Generally, each cigarette contains 1.5-3 mg. When smoking, about 25% of nicotine is destroyed by burning, 5% remains in cigarette butts, 50% diffuses into the space, and only 20% of nicotine is really absorbed by the human body, so some people will not be poisoned if they smoke a box of cigarettes a day. However, the stimulation and damage of nicotine to many human organs are increasing day by day.

? Electronic cigarette: Electronic cigarette, also called steam smoke, is powered by lithium battery. It is a kind of thing that converts liquid tobacco oil into steam through the principle of heating tobacco oil by battery.

E-cigarettes have no harmful components such as tar and suspended particles in cigarettes; It is mainly composed of five kinds of raw materials, namely PG (propylene glycol), VG (plant glycerin), essence, nicotine and flavor additives. Of course, different brands may add some other substances.

It can be seen that although some harmful components are missing from e-cigarettes, nicotine components still exist. At the same time, because other added ingredients in e-cigarettes are still unclear, the problem of affecting the body cannot be ruled out.

? In addition, there are many e-cigarette brands on the market at present, and the purchase channels are also diverse. All kinds of electronic cigarette products on the market are arbitrary in raw material selection, additive use, process design, quality control and so on. The quality of e-cigarette products is uneven, and some products may have quality and safety hazards such as cigarette oil leakage, inferior batteries and unsafe ingredients.

It can be seen that if you need to buy e-cigarettes, it is recommended to choose regular brands and purchase channels to ensure safety and stability during use.
