How does smoking harm you?

ANSWER

Smoking:

Quit smoking now and you'll see fast results. Just 20 minutes after you stop, your blood pressure and heart rate go down. In 2 to 3 weeks, your blood flow starts to get better.

Your odds of heart disease will go down, too. After a year without cigarettes, you're half as likely to get it as you were when you smoked.

  • Clogs your arteries
  • Increases clotting
  • Fills your lungs with tar
  • Thickens your blood
  • Weakens your bones
  • Increases inflammation
  • Weakens your immune system
