How does smoking affect my heart and blood vessels?
The chemicals in tobacco smoke harm your blood vessels and affect the function of the heart. This damage increases the risk for;
1. Atherosclerosis: a disease in which a waxy substance called plaque builds up in your arteries
2. Aneurysms: which are bulging blood vessels that can burst and cause death
3. Coronary artery disease (CHD), narrow or blocked arteries around the heart
4. Heart attack and damage to your arteries
5. Heart-related chest pain
6. High blood pressure
7. Coronary Heart disease: A condition in which platelets (components of the blood that prevents excessive bleeding) stick together along with proteins to form clots which can then get stuck in the plaque in the walls of arteries of the heart and cause heart attack
8. Peripheral arterial disease (PAD), a condition in which plaque builds up in the arteries that carry blood to the head and limbs.
9.Stroke: which is sudden death of brain cells caused by blood clots or bleeding. Smoking increases the risk for stroke.

Every cigarette you smoke damages your breathing and scars your lungs. Smoking causes;
1. Chronic obstructive pulmonary disease (COPD): a disease that gets worse over time and causes wheezing, shortness of breath, chest tightness, and other symptoms. About 80% of deaths from COPD are caused by smoking.
2. Emphysema: a condition in which the walls between the air sacs in your lungs lose their ability to stretch and shrink back. Your lung tissue is destroyed, making it difficult or impossible to breathe.
3. Chronic bronchitis: which causes swelling of the lining of your bronchial tubes. When this happens, less air flows to and from your lungs.
5. Asthma. Also, people with asthma can suffer severe attacks when around cigarette smoke.
