  Smoking is apractice in which a substance is burned and the resulting smoke is breathed in to be tasted and absorbed into the bloodstream. Most commonly, the substance used is the dried leaves of the tobacco plant, which have been rolled into a small rectangle of rolling paper to create a small, round cylinder called a "cigarette".

  Lung cancer occurswhen cells divide in the lungs uncontrollably. This causes tumors to grow. These can reduce a person's ability to breathe and spread to other parts of the body. Lung cancer is the third most common cancer and the main cause of cancer-related death in the United States. Lung cancer develops when normal lung cells change, or mutate, in a way that alters their natural growth and death cycle, resulting in unregulated cell division that produces too many cells. The rapidly dividing cells do not carry out the functions of normal lung cells or develop into healthy lung tissue.

  Cigarettes contain tobacco.All types of tobacco products contain chemicals that can be harmful to your health. Cigarettes, cigars, and pipe tobacco are made from dried tobacco leaves. Other substances are added for flavor and to make smoking more pleasant. The smoke from these products is a complex mixture of chemicals produced by burning tobacco and its additives.

  Tobacco smoke ismade up of thousands of chemicals, including at least 70 known to cause cancer. These cancer-causing chemicals are referred to as carcinogens. Some of the chemicals found in tobacco smoke include: ● Nicotine (the addictive drug that produces the effects in the brain that people are looking for) ● Hydrogen cyanide ● Lead ● Ammonia ● Radioactive elements ● Benzene ● Carbon monoxide ● Tobacco-specific nitrosamines (TSNAs) ● Polycyclic aromatic hydrocarbons (PAHs) Many of these substances cause cancer. Some can cause heart disease, lung disease, or other serious health problems, too. Most of the substances come from the burning tobacco leaves themselves, not from additives included in cigarettes (or other tobacco products).

  ● Less airflow Smokinginflames and irritates the lungs. Even one or two cigarettes cause irritation and coughing. Smoking also can destroy your lungs and lung tissue. This decreases the number of air spaces and blood vessels in the lungs, resulting in less oxygen to critical parts of your body.

  ● Lung cancer Lungcancer is the leading cause of cancer death in the United States. Smoking causes 85 percent of lung cancer cases. Smokers have a higher number of pre-cancer changes in their airways than non-smokers. ● Circulation Cigarette smoking can be very damaging to your circulation system. Because the tar in cigarettes contain harmful chemicals, your blood stream is infected by them when you smoke. When these poisons enter your blood: ● You are at an increased risk for experiencing blood clots, as your blood becomes thicker ● Your blood pressure and heart rate increase, causing your heart to work harder ● Your arteries become thinner, which reduces the amount of blood carrying oxygen as it circulates to your organs

  ● Fewer cilia Thelungs are lined in broom-like hairs called cilia, which clean the lungs. A few seconds after you light a cigarette, cilia slow down in movement. Smoking just one cigarette can slow the action of your cilia for several hours. Smoking also reduces the number of cilia in your lungs, leaving fewer to properly clean the organ.

  ● Brain Smoking cigarettesis also quite harmful to your brain. Smokers are 50% more likely to have a stroke, as opposed to non-smokers. With that, you are twice as likely to die from a stroke. ● Stomach Your digestive system, particularly your stomach, is greatly impacted by smoking cigarettes. The esophagus can be weakened by smoking, allowing acid to travel in the wrong direction through it. This process is better known as reflux.
