Is the higher the price of cigarettes, the greater the harm to the body? I think some cheap cigarettes contain less carbon monoxide than expensive cigarettes. Please make it clear.

The concentration of carbon monoxide in cigarette smoke is about 400ppm, and its binding force with red blood cells is about 2 10 times that of oxygen and red blood cells. Therefore, after carbon monoxide is inhaled into the body, the ability of red blood cells to transport oxygen will be reduced, leading to hypoxia in the body. The heart is an organ with considerable oxygen demand in the human body. If the heart lacks oxygen, it will cause angina pectoris (the condition needs to be explained), and in severe cases it will lead to death.

Nicotine:

Nicotine will have many effects after entering the human body, such as contraction of peripheral blood vessels in limbs, rapid heartbeat, elevated blood pressure, accelerated breathing, mental state changes (such as emotional stability or mental excitement), and promote platelet aggregation. It is the main accomplice of cardiovascular diseases such as cardiovascular obstruction, hypertension and stroke.

Irritant:

Stimulating substances produced by incense will not only stimulate the eyes, nose and throat, but also stimulate the secretion of bronchial submucosal glands, leading to repeated attacks of acute bronchitis and chronic bronchitis.

Carcinogen:

According to the research statistics of American scholars Doll and Peto, the number of deaths caused by smoking accounts for 30% of all cancer deaths, and it is the most influential carcinogenic factor (mainly lung cancer) among all known or predicted carcinogenic factors. If people can quit smoking, cancer mortality will be reduced by one third.

Besides, smoking can also cause gastric ulcer. Smoking in pregnant women can easily lead to premature delivery and underweight of the fetus, and even increase the probability of miscarriage.

(3) The hazards of second-hand smoke:

Environmental tobacco smoke (ETS), also known as second-hand smoke, is one of the most widely distributed and harmful indoor air pollutants, which mainly comes from mainstream tobacco exhaled by smokers and tributary tobacco released by burning cigarette butts.

According to the experimental results, the impact of second-hand smoke on health is similar to that of smokers. For example, if a person doesn't smoke, but his spouse smokes, the incidence of lung cancer will increase by 20% ~ 50%, and the infection rate of innocent people living in an environment filled with cigarette smoke will be 20% ~ 30%.

According to the statistics of the World Health Organization, 53,000 people die from this "negative tobacco poisoning" every year.
