Can e-cigarettes produce second-hand smoke? Can e-cigarettes be harmless without tar?

For e-cigarettes, many people think that there is no second-hand smoke without cigarettes. This understanding is wrong. So, will e-cigarettes produce second-hand smoke? Is there no harm in e-cigarettes without tar? Let me introduce you.

Can e-cigarettes produce second-hand smoke? Because there is no metered smoke after burning when smoking e-cigarettes, only the breath exhaled by people who smoke e-cigarettes, compared with which the smoke and taste are really smaller, so many people think that there is no problem of second-hand smoke in e-cigarettes, but this is actually a wrong understanding.

The particles produced by second-hand smoke atomization of e-cigarettes are mainly aerosol or liquid particles, which contain at least 69 carcinogens, including ethylene glycol, aldehydes, volatile organic compounds and polycyclic aromatic hydrocarbons. At the same time, in the environment of smoking e-cigarettes, the concentrations of nicotine, formaldehyde, acetaldehyde, PM2.5 and other substances in the air will increase by dozens or even hundreds of times. Long-term exposure will increase the risk of chronic obstructive pulmonary disease, cardiovascular and cerebrovascular diseases and various tumors. The data shows that more than 90% of COPD is related to smoking, and e-cigarettes will also increase the risk of COPD.

Although the harm of "second-hand smoke" of e-cigarettes has not been confirmed, it does not mean that there is no second-hand smoke in e-cigarettes, and it does not mean that the smoke of e-cigarettes has no effect on human body.

E-cigarettes are not a "healthy" substitute for cigarettes. You can't choose to use e-cigarettes instead of quitting smoking.

At present, the e-cigarette market is chaotic, and the materials and components used by different manufacturers are different, which leads to different components in the flue gas produced after heating, making the harm of e-cigarettes more difficult to predict and judge.

People who don't smoke or have been exposed to e-cigarettes, especially teenagers, don't take any chances and don't touch them! For the health of yourself and your family, you really must not smoke any cigarettes and try not to smoke second-hand smoke.

Is there no harm in e-cigarettes without tar? The absence of tar in e-cigarettes does not mean that there is no harm. The nicotine content in e-cigarettes is very high. Long-term exposure will have adverse effects on the cardiovascular system, increase the release of catecholamine in the body, lead to increased heart rate, increased blood pressure, vasoconstriction and vascular endothelial damage, promote the occurrence and development of atherosclerosis, increase the risk of myocardial infarction and stroke, and also lead to the activation of tumor factors in the body.

At the same time, e-cigarettes will also produce some new harmful substances unique to electronic nicotine delivery system, that is, toxic substances that traditional cigarettes will not produce, including glyoxal.

A person who smokes/kloc-0.5 to 20 cigarettes a day is four times more likely to develop lung cancer, oral cancer or laryngeal cancer and die than a non-smoker. The risk of dying from esophageal cancer is four times higher than that of non-smokers. The risk of dying from bladder cancer is twice as high; The risk of dying of heart disease is twice as high. Smoking is the main cause of chronic bronchitis and emphysema, and chronic lung disease itself will increase the risk of pneumonia and heart disease, and smoking will also increase the risk of hypertension.

Different brands of e-cigarettes, even different products of the same brand, may have huge differences in the content of toxic substances, and at the same time, e-cigarettes also have serious security risks such as explosion risk.
