Why is tobacco bad?

Tobacco smoke comprises over 50 chemicals that have cancer-causing potential. Regular smoking can reduce a person's life expectancy by up to ten years. Nicotine, a substance present in tobacco, has highly addictive characteristics, making it difficult for smokers to quit.

What effects does tobacco have on your body?
To comprehend why tobacco is so destructive, you must first comprehend how it harms practically every organ in the body. No organ is immune to tobacco's harmful effects, whether it's your mouth, heart, lungs, blood vessels, or skin.

Cardiovascular system
The cardiovascular system is affected by smoking in both the short and long term. Tobacco contains toxins that harm cardiac muscles and cause blood arteries to constrict. This means that smokers below the age of 40 have a fivefold increased risk of a stroke or even heart attack. Tobacco smoke contains carbon monoxide, which binds to hemoglobin as well as makes it more difficult for the blood to transfer oxygen to your organs.

Immune system
Tobacco smoking has also been linked to a weakened immune system, making it difficult to fight illnesses. This makes you more susceptible to sickness and leads to illnesses that last longer and are more severe. Smokers are also twice as likely as non-smokers to contract pneumonia as well as other respiratory infections.

Brain
Smoking has been related to memory loss and brain damage in studies. Tobacco appears to hasten the thinning of the cortex of the brain, which controls language, memory, and perception. Furthermore, studies suggest that smoking may be linked to dementia or even brain shrinkage (cerebral atrophy).

Bones
Tobacco compounds can damage bone cells in addition to meddling with calcium absorption in the body. Smokers repair fractured bones slower than nonsmokers, and they are more prone to fractures and osteoporosis.

Lungs
Smoking damages your airways and alveoli, the air sacs in the lungs. It can cause diseases including lung cancer, pneumonia, and chronic obstructive pulmonary (COPD) disease, all of which are potentially lethal. Tobacco's tar and chemicals pile up in the lungs, irritating the lungs and causing lung damage.

Mouth
Tobacco smoking increases your chances of getting mouth and lip cancer, as well as tongue, larynx, or pharynx cancer. It also promotes gum disease and tooth decay. Because nicotine reduces blood flow towards the mouth, any oral sores or ulcers heal far more slowly.

Reproductive system
According to studies, both men and women can experience fertility issues as a result of smoking. Tobacco compounds harm sperm in males, which can contribute to erectile dysfunction. These substances have an effect on the generation of estrogen, the ovulation hormone in women. They can also lead to irregular cycles and early menopause. In general, smokers are 60% more likely than nonsmokers to be infertile.

Circulatory system
Tobacco smoke contains carbon monoxide, which binds to hemoglobin and reduces the passage of oxygen through the blood. This means that smokers are more likely to have high blood pressure, artery damage, strokes, and blood clots.

Stomach
Because smoking destroys the stomach's protective lining, acids from the stomach run back into the esophagus, causing heartburn and raising the risk of peptic ulcers. Smokers are also at a higher risk of esophageal and stomach cancer.

Skin
Squamous cell carcinoma, which is the second most frequent type of skin cancer, is twice as common in smokers, according to studies. Tobacco smoking also hastens the aging of the skin because nicotine stops oxygen and nutrients from contacting skin cells.
