My mom smokes a lot . She smokes one to two carton of cigarettes in a month . I love my mom very much but she has a lot of health issues . I don't know my mom really well . I was a dopted when I was little and Know I am just finding a lot of this out . I was wondering how can someone who smokes half their life and get this disease and don't want to quiet . She has COPD and Ephazima also . I keep telling her she is slowly killing herself . She keeps saying well something is going to kill me one day . I was wondering on how bad chronic hypoxia can harm your body when a person smokes as much as she does ?
