Allen Carr died of lung cancer, although he had a very successful way of quitting permanently..........

Shelton has this to say on the matter of nicotine addiction and with which I wholeheartedly agree.........
"Many tobacco-slaves try repeatedly to discontinue the use of the poison, but fail to succeed. They return to the poison-vice rather than endure the irritableness, grouchiness, "nervousness," and uneasiness that the prior use of tobacco has induced. They lack the determination to "tough it out," until the nerves have repaired themselves; they lack the will power to carry through; they are unwilling to bear the suffering, but return again and again to the fictional "relief" offered by another dose of their accustomed poison.
To such as these fasting is a God-send. It makes discontinuing the tobacco-vice easy, almost pleasant. Indeed, in but a few days the very taste of the weed becomes obnoxious. It is no uncommon complaint of the old smoker, after a thorough overhauling, that he cannot get a cigar of the right brand, or that he cannot find a cigarette that he likes. The difficulty is not, however, as he thinks, in the tobacco, but in his improved nervous system, and in the regenerated membranes of his mouth and nose. I have seen heavy smokers, who smoked half a life-time, after a fast, become so "sensitive" to the obnoxious fumes of tobacco that the odor of a cigar wafted to their nostrils from a block away was objectionable to them."

***************************************
The Lungs can be permanently damaged with the life-long habit of smoking, but the writings of Natural Hygiene testify to the effectiveness of the fast in healing the Lungs, as being the first organ to be favorably influenced, especially with sunlight directly exposed onto the back of the sufferer.
Lungs will heal after giving up smoking, but they are healed much more rapidly whilst fasting and the exposure of sunlight.
