If you quit smoking how long does it take for the oxygen level in your blood to be normal?
A doctor has provided 1 answer
Unknown: Improvement happens quickly (1 hour) but if smoking has damaged your lungs with emphysema or COPD you may never regain totally normal blood oxygen.This not to say i don't want you to quit-every cig you don't smoke helps you!
