1. Cancer:Smoking leads to many types of cancer such as: Lung, nose, mouth, larynx, trachea, esophagus, stomach, pancreas, kidney, bladder, cervix, bone marrow and blood... When smoking, in addition to causing local damage to parts of the respiratory system such as nose, mouth, pharynx, larynx, trachea, 41,000 chemicals in cigarettes (a large proportion of which are known to cause cancer) enter the body through the alveolar walls in the lungs, seeping into the body. These chemicals have the ability to create mutations in the body's cells, causing them to multiply uncontrollably, leading to cancer.
2. Wrinkle formation and aging:Smoking leads to the appearance of wrinkles (especially around the eyes and lips), age spots, puffy eyes, dull, dry and lifeless skin. This is because the chemicals present in cigarettes cause the capillaries under the skin to contract, restricting blood flow to the skin. The lack of blood and oxygen makes the skin look dull and lifeless. Over time, this leads to permanent damage to connective fibers such as elastin and collagen, the structures that keep the skin firm and smooth – resulting in permanent wrinkles and premature aging.

3. Causes heart failure, making you at many times greater risk of cardiovascular disease and stroke:A smoker is two to four times more likely to develop coronary heart disease and stroke than a non-smoker. The chemicals in cigarette smoke affect the entire composition of the circulatory system and blood-forming organs; making the blood vessel walls thicker and more prone to clot formation. It also causes blood vessel constriction, increases blood pressure, and leads to plaque formation – increasing the risk of cardiovascular disease.
4. Damages and damages the lungs, leading to respiratory failure:Smoking leads to the accumulation of a significant amount of chemicals in your lungs, airways and entire body. All these residues will clog your lungs in the long run, leading to respiratory problems and reduced lung function. The reduced lung function leads to lack of oxygen and fresh blood to various organs and parts of the body, making the body always tired and short of breath. Smoking can lead to chronic obstructive pulmonary disease, emphysema, chronic bronchitis, pneumonia, lung infections, asthma and increases the risk of tuberculosis.
5. Causes premature ejaculation and decreased sexual desire:A condition often associated with older men is decreased libido, premature ejaculation is quite common in young men who are addicted to cigarettes. In the case of premature ejaculation, because the chemicals in cigarettes reduce blood flow, reduce sensation in the penis, cause cardiovascular disease and lack of stamina. All these factors together lead to a decrease in male ability, causing premature ejaculation. Smoking directly affects sexual desire, stamina and sex appeal. Smokers have a lower desire for sexual activity than non-smokers.
6. Leading causes of erectile dysfunction:Smoking causes blood vessel constriction which directly leads to the inability to maintain an erection (because smoking reduces blood flow to the penis). The chemicals in tobacco also cause the blood vessels around the penis to dilate, and these chemicals can create blockages in the arteries that reduce blood flow to the penis when aroused. Furthermore, nicotine is known to directly affect the blood vessels supplying the penis, making it difficult to get and maintain an erection.
7. Causes brittle bones:A large number of studies have found that smoking leads to reduced bone density due to increased calcium mobilization from the bones into the blood. This loss of bone density leads to early onset of osteoporosis (especially in women because smoking affects estrogen production), joint pain, and even tooth loss due to excessive bone density loss in the jawbone.
8. Causes yellow teeth:Cigarettes contain tar, a chemical that turns teeth yellow. In addition, when smoking, the smoke will destroy beneficial bacteria in the mouth, increasing the amount of saliva secreted, which is the leading cause of tartar formation.
9. Causes bad breath:Smoking can lead to very strong and persistent bad breath that is difficult to get rid of. In addition to killing the beneficial bacteria in the mouth, smoking also causes digestive problems, sore throats and chemical buildup in the oral cavity (diseased throats and stomachs are one of the main reasons for bad breath, in addition to poor oral hygiene). Smoking creates favorable conditions for fungi to grow in the oral cavity, leading to the sign of “Smoker’s Palate” (the roof of the mouth is covered with chemical residues in cigarettes, forming small red spots on the roof of the mouth) is also one of the main reasons why smokers’ breath has an unpleasant odor.
10. Causes blindness:Smoking also has a huge impact on your vision and can cause blindness. Smoking increases your risk of cataracts, macular degeneration (normal age-related damage), optic nerve damage, and in short, you can go blind if you smoke.
