Eleven types of cancer, including lung, stomach, pancreatic, bladder, liver, oral cavity, and sinus cancers, are significantly associated with smoking. Although the relationship between smoking and bladder cancer is not as significant as for lung cancer, the incidence of bladder cancer in smokers is twice as high as in nonsmokers and is associated with the amount of cigarettes smoked per day. Kidney cancer: Studies over the past 40 years have confirmed that the risk of kidney cancer in smokers is 1.1-2.3 times greater than in nonsmokers and is strongly related to the amount of cigarettes smoked and the age at which smoking began. Penile erectile dysfunction (ED) and premature ejaculation: Smoking can cause ED and premature ejaculation in men and is one of the organic factors of ED, that is, it can cause permanent non-erection of the penis. The main cause is irreversible damage to the blood vessels of the penis. The impact of alcohol consumption on ED is even greater and has more factors. Smoking can cause premature ejaculation through factors such as suppression of androgen production and carbon monoxide damage to the ability of red blood cells to carry oxygen.

The rate of death from breast cancer is 25% higher in women who smoke than in non-smoking women. Passive smoking: Smoking harms people, and passive smokers are five times more likely to be harmed than smokers. We already know the harm of “second-hand smoke”, recently there is an international “third-hand smoke”, the so-called “third-hand smoke” is to smell the smoker’s clothes, ashtrays and room The so-called “third-hand smoke” is the smell of smoke residue on the smoker’s clothes, ashtrays and rooms, rather than direct passive inhalation of smoke, “third-hand smoke” on the human body is also very damaging.
