What benefits can I expect within the first week of quitting smoking?

Well, here's a timeline that shows how quickly the effects of smoking can be undone. If you quit smoking today, the following changes will happen during the first week:
  • After 20 minutes your blood pressure will return to normal.
  • After 8 hours the carbon monoxide (a toxic gas) levels in your bloodstream will drop by half, and oxygen levels will return to normal.

  • Within 72 hours your bronchial tubes will relax, and your energy level will increase.
