 [ Symptoms ] i smoked cigs for 1 month averaging about 3 a day just wondering if any irreversible was done i did quit since then i started smoking for a month after a period of depression a couple of months ago 2 3 cigs most days with a couple more on bad days i would estimate i probably had 4 packs total over the period i went cold turkey as i started to get my life together and hated the ill feeling from them i exercise regularly and eat healthy and i am still young i would just like to clear my head and hear that i did no damage permanent to my lungs i know it takes a bit to recover hopefully to 100 [ Disease ] good for you for making the sensible decision not to rely on cigarettes for stress control it is much better to learn good coping techniques than to self medicate the good news is you probably did not irreversibly harm your lungs by smoking lightly for a month even heavier smokers can undo the damage to their lungs to a certain extent by quitting if you are young and you maintain a smoke free lifestyle you should do just fine i hope this sets your mind at ease
