Heart, lungs, skin - literally all organs are affected by cigarette chemicals.

The cardiovascular system. Substances contained in tobacco harm the heart muscle, constrict blood vessels. It has been proven that heavy smokers under 40 are five times more likely to develop heart attacks, strokes.

Lungs. Smoking destroys the airways, alveoli, causes chronic obstruction, lung cancer, pneumonia.

Brain. Tobacco accelerates the process of thinning the cortex of the organ responsible for memory, perception, speech functions. Smoking can cause dementia, brain atrophy.

Stomach. Nicotine destroys the protective membrane of the organ, as a result of which acids damage the mucous membrane. Because of this, the risk of ulcers in the stomach and duodenum increases..

Reproductive system. In men, tobacco damages the seminal fluid, eventually causes impotence, in women it affects the production of estrogens, which are responsible for ovulation.

Immunity. Smoking interferes with the body's ability to fight infections, making illnesses longer and more severe. Smokers have a much higher risk of developing pneumonia..

Circulatory system. Carbon monoxide in tobacco smoke, bound with hemoglobin, inhibits the flow of oxygen into the blood. Smokers are more likely to suffer from hypertension, thrombosis, strokes.

Muscle. Typically, smokers have weakened muscle strength, mass and flexibility.

Bones. A bad habit prevents calcium from being absorbed, which adversely affects bone cells. Smokers are more prone to osteoporosis, fractures, and their bones grow together longer than non-smokers.

Skin. Studies show that smokers are twice as likely to develop the second most common type of skin cancer, squamous cell. Nicotine also reduces the access of nutrients, oxygen to the cells of the epidermis, due to which the skin ages much faster.

Oral cavity. With regular smoking, the risk of neoplasms in the mouth, larynx, pharynx, tongue, lips increases. Gum disease, caries develop. Sores heal slowly due to slow blood flow to the mouth.

Psyche.

Because smoking has a short-term sedative effect, smokers become addicted to the cigarette. When you smoke, the body releases dopamine, which activates the reward system in the brain. But over time, tobacco use inhibits the production of a person's own dopamine, and a bad habit only increases stress, depression, anxiety..

Energy. Smoking disrupts the circulation of oxygen and nutrients, so the vast majority of smokers are less active than non-smokers.
