Maybe 5-8 years: It is hard to find research on that particular issue, but there are tests that a Pulmonary Specialist can perform (FEV1, lung capacity, arterial blood gases), that could check how good your lungs currently are. For long time smokers, 10-15 years to reduce risk of lung cancer to normal population.
