From the calculation point of view, a 2ml magazine contains about 600-700 cigarettes, which is less than 3 packs according to the standard of 10 cigarettes. The frequency of smoking a cigarette a day is similar to that of smoking a pack of cigarettes a day, and it is not beyond the scope of use.
The nicotine content of an ordinary cigarette is 1.5-3mg, one pack is about 30-60mg, and three packs are close to 90- 180 mg. 5% of cigarette cases are 50ml, and the capacity of 2ml contains 100mg of nicotine, which is close to the low value of cigarettes. The nicotine intake of e-cigarettes is not much.
However, it should be noted that not all the mentioned nicotine will be absorbed. At present, it is estimated that only 20% of nicotine in cigarettes will enter the human body, and there is no similar study on e-cigarettes. So the assumption just calculated is that the nicotine absorption rate of e-cigarettes and cigarettes is equal or similar.
There is danger:
All along, businesses have been promoting that e-cigarettes do not contain harmful ingredients such as tar and suspended particles, and even in product introduction, they are under the banner of "smoking cessation artifact" and "clearing the lungs".
As we all know, the safety of e-cigarettes has not been fully scientifically demonstrated. So far, there is no systematic information on the safety evaluation of e-cigarettes at home and abroad, so what potential risks e-cigarettes will bring to users' health is still uncertain.
