According the Centers for Disease Control and prevention, smoking causes 1 in 5 deaths in United States. It can negatively affect almost every organ in your body, but much of this can be reversed by cigarette smoking cessation. Within 2 to 5 years after quitting smoking, your risk for stroke could fall to about the same as a nonsmoker’s. After ten years, your risk of lung cancer drops by half. For many men, the promise of better sexual performance can be enough for them to stop smoking. This strategy has been so effective that it has been used as anti-smoking campaigns.
