Quit Q&A

How soon after quitting will my health improve?

Smokers benefit almost immediately from quitting. Within 20 minutes, blood pressure and pulse begin to improve. After a day, most of the carbon monoxide will be gone and some will already notice improved shortness of breath. After one year, the heart attack risk drops 50% and similarly after 10 years, the lung cancer risk drops 50%. The risk of stroke normalizes after 5-15 years and the risk of heart attack normalizes after 15 years.
