There is enough evidence to prove that e-cigarettes are harmful to health. What harm does e-cigarette do to human body?

Although e-cigarettes are less harmful than ordinary cigarettes, they are still harmful. Nicotine produced by heating can seriously harm blood vessels and heart. Ordinary cigarettes will inhale tar and nicotine when smoking, which is very harmful to the lungs.

1. Long-term smoking of e-cigarettes will lead to vasoconstriction and increased pressure, which will further increase the load on the heart and eventually lead to heart disease. Although e-cigarettes are not burned but heated, the harmful substances in the smoke pipe will still endanger our health. Nowadays, many people think that smoking e-cigarettes will have no effect on their health. It's actually wrong. Nicotine, the smoke oil component in e-cigarettes, will still cause harm to the body.

Therefore, in our daily life, we should try our best to give up cigarettes or electronic cigarettes. Because they all have a great influence on the body. A person's blood pressure suddenly rose while smoking e-cigarettes, but it dropped again after stopping for a week. As we all know, elevated blood pressure can easily lead to cardiovascular diseases. So for the sake of our health, we must give up smoking. One experiment said that the lungs of non-smokers and smokers are different. The lungs of non-smokers are red and healthy. Moreover, smokers' lungs are black and look terrible. It can be seen that long-term smoking is extremely harmful to our lungs. Not only that, it can also lead to cancer in severe cases. Although that cigarette is good to smoke, our health is more important. We smoke in public places, and people around us are actually smoking secondhand smoke, so secondhand smoke is also very harmful to the lungs, which is no different from those who smoke. Then, if we insist on smoking, it will not only harm our own health, but also harm the health of others, so it will not be worth the candle. Therefore, we must quit smoking and e-cigarettes.
