Cigarette smoking has been linked to many health problems, including emphysema, lung cancer, and heart disease. However, these are far from the only effects of smoking on your health; some of the most serious and dangerous effects of smoking on your health include the following three factors

1) What Is Smoking?
Smoking, or tobacco use, is a very dangerous habit. According to several research studies, smoking is injurious to your health in several ways. Smoking can damage almost every organ in your body and cause lung cancer, cardiovascular disease, and even erectile dysfunction.
2) How Does It Affect the Brain?
Because nicotine acts as a stimulant, it is also highly addictive. It causes levels of dopamine, a neurotransmitter that produces feelings of pleasure and well-being in your brain, to rise sharply. When you’re experiencing nicotine withdrawal symptoms—which are typically more intense than what you felt when trying to quit—dopamine levels drop, leaving you feeling anxious and irritable. That can then lead to more cravings for nicotine.
3) Why Do People Smoke?
Tobacco contains nicotine, a naturally occurring chemical that’s addictive. Some people use tobacco to manage stress, cope with anger, or relieve boredom. Regardless of how you use it, smoking causes long-term damage to almost every organ in your body. Cigarette smoke can be downright injurious to your health. Here are some ways cigarettes impact your body.
4) How Does it Affect Lungs?
Cigarette smoke contains over 7,000 chemicals—including at least 70 that are known to be injurious to human health. As a result, smoking cigarettes causes several serious illnesses and conditions, such as heart disease and lung cancer. It also aggravates conditions brought on by other factors like asthma or emphysema.
5) Other Health Risks of Smoking
Nonsmokers are at increased risk for lung cancer and other diseases when exposed to secondhand smoke. Nonsmokers who live with a smoker have an increased risk of getting lung cancer as great as that posed by smokers themselves. This is especially true for women and girls. Secondhand smoke also can cause middle ear infections in children and can aggravate asthma symptoms in both children and adults. Secondhand smoke causes an estimated 3,000 deaths from lung cancer each year among adult nonsmokers; more than 41,000 deaths from heart disease; nearly 38,000 deaths from stroke; and more than 430 deaths from acute bronchitis in children under 18 years old.
