Giving up smoking is the single most important step men can take to improve their health. Smokers are 2-3 times more likely to have a heart attack. Tobacco smoke contains nearly 4,000 different substances, including ammonia, arsenic, cadmium and carbon monoxide. The more cigarettes smoked and the younger you start, the greater the risk. Smoking is linked with cardiovascular disease, lung disease, gastrointestinal tract disease, cancers and sexual disorders.
Many smokers try several times before they succeed.
But it can be done. Within 8 hours all the toxic carbon monoxide has been washed out of your blood and oxygen levels return to normal. Within 24 hours the chances of a heart attack have begin to decrease. Within 48 hours your sense of taste and smell begin to recover. Within 72 hours you can breathe more easily as lung capacity increases.
