Short Term Affect on the body Changes Brain chemistry- body craves more Withdrawal symptoms In a s little as 30 minute after last use. Increased respiration and heart rate Dulled taste buds Bad breath, smelly clothes, hair, and skin
Long Term Affects on the body Diseases of the Respiratory System (Lungs) A. Chronic Bronchitis: is an irritation of the bronchi. The cilia become useless; tar builds up causing a chronic cough and excessive mucus. B. Emphysema: is a condition which destroys the tiny air sacs in the lungs. These air sacs are needed to absorb oxygen into the blood stream. A person with advanced emphysema can use up to 80% of their energy just to breath. C. Lung Cancer: is the leading cause of caner deaths in males. Cilia are destroyed and extra mucus can not be expelled. Cancer cells grow in these conditions, block the bronchi and move into the lungs. African Americans tend to suffer most from Tobacco related lung caner
Diseases of the Circulatory System (Heart) Nicotine makes the heart work harder and speeds up the pulse. Smoking constricts the blood vessels, which cuts down on circulation. Nicotine contributes to plaque build up in blood vessels. This leads to hardening of the arteries. This condition increases the risk of a heart attack. Nicotine also increases blood pressure and can lead to strokes.
Nervous System Addiction Increase risk of strokes- which occur in the Brain
Digestive system Possible mouth, pharynx, larynx, stomach, pancreas cancers Increased nausea, diarrhea
