tobacco risks, social and health risks.
Fact: Tobacco Kills you slowly
Medical fact: people die from coranary heart disease and lung cancer because of tobacco
Tobacco reduces a person's ability to taste and smell.
As tobacco reduces the amount of oxygen to the brain and muscles, it is responsable for headaches, "veriges", and diminishes exercise endurance.
long-term smoking can lead to fatal heart attacks, strokes, emphysema, and cancer.
Coronary linked problems
- Nicotine increases heart rate & blood pressure. (Heart rate can rise by 30% in first 10 min of smoking.)
- Carbon monoxide is present in blood reducing the amount of oxygen
in blood. Because of the reduced amount of oxygen in blood, the heart can’t
work properly.
- Good HDL cholesterol reduced & bad cholesterol increased creating plaque formation in blood vessels. So blood vessels narrow & less O2 reaches heart, making it work harder.
- The blood tendency to clot is increased. These blood clots can block blood flow causing gangrene, strokes, and heart attacks.
- ie. if flow in coronary vessel gets blocked, part of the heart dies, it’s a heart attack. If the blockage is extensive, the whole heart is damaged & stops pumping resulting in death.
