Diagnosing Tobacco Use Disorder

Your doctor will ask about your symptoms and medical history, and perform a physical exam. He or she will ask you specific questions about your tobacco use, such as how long you have been using tobacco and how often you use it.

Your doctor can test your lung function and compare the results to those of a non-smoking person. The results can be given to you as your “lung age.” Knowing your “lung age” right after having the test done may help you to stop smoking. * ³
