Tobacco Tobacco contains nicotine which is the addictive drug in cigarettes. People smoke to reduce craving for nicotine, which is a poisonous stimulant.

Tar is what gives cigarettes there flavor. Tar is a thick, sticky, dark fluid produced when tobacco burns. Tar paralyzes or destroys cilia, the waving hair like projections that work to keep the respiratory tract clear. Several substances in tar are known to cause cancer. Carbon monoxide is found in cigarettes, and is the same gas in automobile exhaust fumes. It unites with red blood cells, preventing them from carrying the oxygen needed for energy to the body’s cells. What is in a Cigarette?

What Tobacco does to the body Smoking can have long term and short term effects on the body. Smoking causes diseases of the Respiratory and Circulatory systems.

Diseases of the Respiratory System Chronic bronchitis: a condition in which the bronchi are irritated. As cilia become useless, tar from cigarette smoke builds up which results in chronic coughing and excessive mucus secretion.

Diseases of the Respiratory System Emphysema: a condition that involves the destruction of the tiny air sacs in the lungs through which oxygen is absorbed into the body. As the walls between sacs are destroyed, they lose their elasticity and provide less total surface from which oxygen can be absorbed. More breaths are required. So instead of using 5% of one’s energy to breath they used of to 80% just to take a breath!

Disease of the Respiratory System Lung cancer: directly linked to cigarette smoking. Leading cause of cancer deaths among males. Cilia are destroyed and extra mucus can’t be expelled. Cancerous cells can grow in these conditions, block the bronchi and move to the lungs.

Circulatory System

Diseases of Circulatory Nicotine makes the heart work harder and speeds up the pulse. Smoking constricts the blood vessels, which cuts down on the circulation, or blood flow, to the limbs. This can result in tingling feelings in hands and feet of the smoker. Nicotine contributes to the formation of plaque buildup in the blood vessels. The formation of these fatty deposits in the arteries increases the chance of arterioclerosis, or hardening of the arteries, and gradually clogs the blood vessels. This condition increases the risk of heart attack and stroke.

Smoking during Pregnancy At least 2,800 deaths of low birth weight babies are cause by mothers who smoked while they were pregnant. Smoking while pregnant is associated with small fetal growth, an increased chance of spontaneous abortion and prenatal death, increased stillbirths, as well as growth and development problems. Nicotine passes through the placenta, constricting the blood vessels of the fetus. Carbon monoxide reduces the oxygen levels in the mother’s fetus’s blood. After the baby is born nicotine can be passed to the child through breast milk.
