qqp question1: I am 20, smoked a couple packs of cigarettes in my life and now I am having sinus pain and cough, can it be cancer? question2: I smoked cigarettes in my early 20s, quit for 7 years and then smoked lightly (2 packs a week, or so) into my mid 30s and have now been totally quit for 5 years or so. Is smoking still going to kill me?
