First of all, we know that there is a harmful component in cigarettes, which is very harmful to our health, and that is nicotine. There are other harmful ingredients, but this is the most harmful ingredient. ) How harmful is nicotine to people? Let me give you another example, that is, I don't know if you have heard of such a thing, that is, put a cigarette in a cup full of water, soak it for a while, and then this glass of water will die. You will die, so you know the harm of smoke. If there is really nothing in the smoke, how can a glass of water kill you? If nicotine is not very toxic, how can a cigarette kill you? So, cherish life and stay away from tobacco.
Another example is smokers in life. There are too many reasons to smoke, but the result is shocking. There are too many people smoking, and there are many in our family. Let's just say that everyone in our family smokes except women and children, and they smoke heavily. In a word, our man has been smoking since I can remember. You can say that you never leave. How serious is it? I've seen it. Of course, long-term smokers will have symptoms, that is, yellow fingertips and black teeth. Yes, have you seen them? That is, we often brush our teeth and can see outside. Although it may be a little yellow, our teeth are black inside, basically pure black. So, do you still say smoking is harmless?
Smoking is harmful to health, which is not only a sign, but also a warning to remind us not to slide into the abyss.
