Consider this: Within 20 minutes of your last cigarette, your heart rate and blood pressure will drop, according to the American Cancer Society. Within a few weeks, your blood circulation may improve. A month after you stamp out that last cigarette butt, you may notice that you cough less and don't become winded so easily, making you feel more youthful and energetic.
Your health will continue to improve in the months and years that follow if you avoid tobacco. Importantly, your risk for heart disease, lung cancer, and other cancers that can cut life short will plummet.
