First of all, understand several harmful substances: nicotine tar and carbon monoxide. Their role is: addiction, blackening your lungs and cancer risk. E-cigarettes have no tar and carbon monoxide, but nicotine. The nicotine content of a cigarette is about 65438 0.5-3mg,
About 20% will be absorbed with heating and combustion. If a person smokes one cigarette a month, he will receive 80 milligrams of nicotine a month. 6mg cigarette oil like this one in the picture is rarely sold. 80% people smoke 3mg, and the data in the picture is that only diluted amount of e-cigarettes will be heated and emitted into the air, and so on. So the absorption is about 20%, so a bottle of cigarette oil can be smoked for one month, which is 36mg.
The CDC's assessment of e-cigarettes is that e-cigarettes are a new thing, and the health impact of long-term use is unknown.
E-cigarettes usually contain nicotine, which is harmful to fetal development and cognitive development of teenagers under 25.

Let's talk about it. In this irregular market, it is normal for good and evil people to mix. The price of e-cigarettes sold in the market ranges from 50 yuan to 1500 yuan. Think about it, there is no advanced technology. Isn't the reason why the price gap is so big all kinds of unevenness?
Indeed, the nicotine content of those cigarette oils or bombs fluctuates greatly, and many of them are higher than that of real cigarettes. ?
Besides nicotine, the aerosol of e-cigarettes is not completely harmless. They contain some tiny particles that may cause cancer, and may also contain some heavy metals and volatile mixtures [15]. Some studies also show that e-cigarettes increase the risk of heart disease and cancer.
In short, e-cigarettes are not good for health, but if the damage of flue-cured tobacco is 100, e-cigarettes are 80. As a smoker, the best way is to quit smoking, so why not try e-cigarettes that do less harm?
