(nicotine is the addictive portion) Smoking permanently damages alveoli (air sacks) in lungs- hard to breathe. Built like tiny balloons (breathe in, alveoli help absorb oxygen in body, breathe out, alveoli help rid of the carbon dioxide. Damages structure of alveoli- makes less stretchy and harder for lungs to take in oxygen and rid of carbon dioxide: shortness of breath and tiredness, heart works harder to give body oxygen, damage leads to copd. Less well-off = more likely to smoke. Stopping smoking at any age is associated with clear health benefits. Health consequences of smoking cessation: lower risk of coronary heart disease and cardio-vascular disease. Modifiable factors: tobacco use *, physical inactivity *, unhealthy diet, excess body weight *, alcohol, environment.
