Stop smoking for one: There is no evidence that anything other than time and continuing to be smoke-free is necessary for lungs to heal. Am sure that a healthy diet and exercise will help you feel better sooner. It is quite common for a productive cough to begin after people stop smoking, since the lungs are getting rid of all the junk that has been put in them by smoking. This resolves in several weeks to months.

Stop smoking: If you mean how can you help your lungs recover from smoking. You can't help anybody elses' lungs recover, so am not sure what you mean. When people stop smoking, it may take many months to clear out the "crud" accumulating in the bronchial passages, but they will eventually clear out. Nothing speeds this process, and it won't happen unless you stop or cut down significantly on smoking.

How long should your lungs take to recover from smoking?

Some quick some slow: Many of the benefits of quitting smoking can be felt in the first my understanding is that it takes about 7 years for all the cells in the lungs to be replaced with new ones. You should consult your doctor to assess any specific concerns or symptoms and follow any diagnostic recommendations offered (tests etc).

What do the experts think, should my lungs ever fully recover from 6 years of heavy pot smoking?

Yes in six years.: Spray saline into your nostrils frequently to flush out allergens and irritants. You will get the best care in a long term relationship with a provider who knows you over time. Discuss this with that provider.

Not completely: Congratulations on having stopped smoking. By now you should have experienced a significant improvement in your ability to breathe. Your lungs will not return entirely to normal but they will improve greatly. You have also greatly cut down on your risk of copd, emphysema, and lung cancer. Always remindi your doctors however that you were at one time a heavy smoker. Unfortunately you still remain at risk of developing cancer because of the amount you did smoke. However, that risk is greatly reduced by having quit. It's just that the risk does not drop to zero.

Can my lungs recover from smoking?

In same part: It all depends. Number of pack years, age, present damage, pulmonary function testing, additional diseases and so on. The lungs certainly do not worsen off smoking. Often there is nice improvement within the first two months. Check with your lung doc.

Depends: On how much you smoked and for how long, but in general marijuana smoke is nowhere near as toxic to the lungs as tobacco smoke is, despite the old wive's tales of "one joint=pack of cigarettes." studies of occasional marijuana smokers have shown little or no changes in lung function studies. Very heavy smoking however may cause bronchitis, emphysema and cancer. I am not aware of any data on this.
