I took it along with the recommended Lobelia tincture, but I only smoked on and off for two years and didn't notice that the two potions had any *measurable* effect on my lungs. Maybe my lungs weren't that bad to begin with.
Strongly, strongly suggest: there is a guy called Trapper on here, his handle is Trapper/kcmo (he has his own forum), who is a longtime smoker,!still smokes!, who *cured* his own emphysema by, I think, using a nebulizer and Colloidal Silver . I strongly urge you to contact him via his forum or private message.
Hope this helps and GOOD LUCK! Get on it, sounds like time is of the essence!
