If you're smoking a cigarette right now, I have good news for you: if you don't ever pick one up again, your body will go through amazing transformations within minutes of finishing your last one.

20 minutes after your last cigarette:

Your blood pressure and pulse will lower and return to normal. The temperature in your hands and feet increase.

After 12 hours:

The carbon monoxide level in your blood will lower and return to normal. Blood oxygen begins to increase. You'll feel more alert, sleep better, and be stronger.

After 24 hours:

Your risk of heart attack drops significantly.

After 48 hours:

Nerve endings begin to regrow and your sense of smell and taste will return.

After about 3 months:

Your circulation will improve, walking will be easier, and you'll cough less. Lung function will be markedly improved.

Between 1 and 9 months:

You'll have less sinus congestion, fatigue, and nearly no shortness of breath.

After 1 year:

Your risk of coronary heart disease is half of what it was when you smoked.

After 5-15 years:

Your risk of stroke returns to normal, as if you never smoked at all.

At the 10 year mark:

Your chance of developing smoking-related cancer is about the same as a non-smoker. Diet and smoking contribute to 60% of cancers.

After 15 years:

Your risk of coronary heart disease and heart attack is that of a non-smoker. Your risk of death has dropped to that of a non-smoker.

You'll also save a ton of money by not smoking too. Who wouldn't want that?
