I smoked for two years about 25 cigarettes a day and have quit 5 months ago. I am very concerned about my long term risks and when they will diminish. I only learned of the continued risks just prior to quitting, I am very upset to learn that it takes a very long time. Do the timelines apply to a shorter term smoker? I am now 49 years old and am not able to sleep because of the worry. I did read a study from the european cancer journal that stated it takes a year recovery for every year smoking. I would also like to know how long it would take to clear the tar. The website for thae study is www,eurjcancerprev.com/pt/re/ejcp/abstract. I really was not aware of the total health effects from smoking and am wrought with anxiety and am paralyzed with fear and am hoping you will reply.
