I quit smoking completely im just using an e cig now but after i quit iv e developed a cough is that a good sign that my lungs are clearing?

Yes!: Congratulations on stopping smoking. Smoking paralyzes cilia, little hair-like structures that clean the bronchial tubes with a sweeping motion.Now they're able to work ; start sweeping out the years of smoke residues that have accumulated in your lungs.The cough will decrease in coming months.

What's good: Is that you quit smoking. Have heard a lot of anecdotal stories about post-quit coughing and lung clearing but if the cough persists i would recommend you see your doctor and perhaps obtain a chest x-ray to be certain. Congratulations on quitting!

Could be: It's great that you've made this good health decision to quit smoking. Many who quit smoking go through a period of coughing that clears mucous and toxins out of their lungs. There are otc medications like music Mucinex (guaifenesin) that may help to speed up the process. But i would recommend you see your doctor if this persists.
