Almost everyone knows that smoking is harmful to health, but most people do not pay attention to it. Tobacco smoke contains a lot of carcinogens, which can cause cell cancer and malignant tumors.
can you get cancer from e cigarettes?
We all know that cigarettes contain many carcinogens, and smoking is also the biggest cause of lung cancer in the world. So, will the situation be better if you switch to e-cigarettes?
Let’s first look at who is causing cancer in cigarettes. Many scientific researches around the world have shown that the harm of tobacco comes from toxic substances such as tar, carbon monoxide, and other metal compounds produced when it is burned. Nicotine is only addictive, and it is by no means the “culprit” that tobacco harms public health.
The strongest carcinogenicity in tobacco is the first-level carcinogen nitrosamines. Cigarette smoke contains a lot of tobacco-specific nitrosamines, such as NNK, NNN, NAB, NAT…Among them, NNK and NNN have been identified as strong lung cancer-causing factors by the WHO. However, the Centers for Disease Control and Prevention （CDC） of the United States has issued research data twice. It is the first time that the NNN content in e-cigarette smoke is only 1/380 of the NNN content of cigarette smoke, and the NNK content is only 1 of the NNK content of cigarette smoke. /40; It is pointed out for the second time that the average concentration of NNAL in the urine of smokers is 285.4 ng/g creatinine, and the average concentration of NNAL in the urine of e-cigarette users is 6.3 ng/g creatinine, which is the content of NNAL in the urine of e-cigarette users Only 2.2% of smokers.
These studies basically concluded that e-cigarettes do not contain the main carcinogens in cigarettes.
Let’s look at the main components of e-cigarettes. The main components of e-cigarettes are nicotine, propylene glycol, glycerin and flavors. Propylene glycol and glycerin are both edible and medicinal substances. Flavors are well understood and used for flavoring. The three are the most common substances in daily food. Finally, nicotine, as I said above, is only addictive and does not cause cancer. In the list of carcinogens released by the WHO, nicotine is not even the last level four carcinogen.
Of course, during the atomization process of e-cigarettes, glycerol and propylene glycol, at high temperatures, these two substances will have a cracking reaction to generate formaldehyde, especially high-power atomizers, this is undoubtedly. However, formaldehyde will be released above 400°， which means that e-cigarettes with large smog are not safe. The higher the temperature and the greater the smoke, formaldehyde is also produced.
Judging from the above content, compared with cigarettes, electronic cigarettes reduce a lot of carcinogens, and only at high temperatures will they release carcinogens such as formaldehyde.
