08/01/25, Immediate Health Benefits of Quitting Smoking

 The immediate health benefits of quitting smoking are substantial:

• Heart rate and blood pressure, which are abnormally high while smoking, begin to return to normal.
• Within a few hours, the level of carbon monoxide in the blood begins to decline. (Carbon monoxide reduces the blood’s ability to carry oxygen.)

Within a few weeks, people who quit smoking have improved circulation, produce less phlegm, and don’t cough or wheeze as often.

• Within several months of quitting, people can expect substantial improvements in lung function .
• Within a few years of quitting, people will have lower risks of cancer, heart disease, and other chronic diseases than if they had continued to smoke.
