Philpalm is absolutely right. Vaping will ensure that the damage to the lungs will continue and once they are damaged, the damage cannot be reversed. Quitting smoking will stop the damage from smoking from continuing to occur and does allow the lungs to clear out the "gunk", but the damage already done can't be undone. The lung function will continue to decrease, but at the same rate as in people without lung disease, not at the accelerated rate that occurs while smoking.

CBD oil does help with anxiety and with a number of co-morbidities, but it generally does not affect the lungs. FECA oil, which is a more powerful derivative that is produced using a different procedure is said to have some effect on the lungs. Healing them is not among the effects, but it seems they may be able to help make the lungs more efficient, much as daily exercise does.

Vaping always uses a carrier liquid, usually vegetable glycerine and propylene glycol, not good, just safer than smoking. There is evidence that vaping damages the immune system.Get hit by a car instead of a truck.
Your lungs will feel better after stopping smoking, if you have already stopped vaping will make them worse, and is recommended only as a aid to stopping smoking.
Eating cbd may have several beneficial results, especially for anxiety, any effect on the lung will still be present (with a higher dose than vaping), but as of yet only smoking cessation has shown actual healing effects, and that, only if young enough. Emphysema will not be reversed, but may be slowed.
