Smoking tobacco isn’t a medical condition of its own, but continued smoking does cause all kinds of medical conditions like emphysema, lung cancer, and throat cancer. It can also have an impact on which types of birth control are safe to use. Women under 35 who smoke and have no other medical conditions can usually use the pill with reasonable safety, but should definitely talk to their doctor about alternative methods. Women over 35 who smoke more than 15 cigarettes a day should steer clear of the pill, ring, or patch.
