I know there are a lot of people who think that since smoking has never done any serious damage to them, that there will never be any damage done or if it is some damage, it will never be anything too serious. Honestly speaking, this is not true. There are quite a number of things that can and usually do go wrong. One of the major problems with smoking is the fact that it actually causes a lot of serious breathing problems. This is usually the most common problem shared by nearly all smokers. The problem can come from your lungs being filled with toxic smoke from a cigarette and also can be from the many forms of cancer you can develop as a result of smoking. Although lung cancer is the number one type of cancer you can get, there are still other forms that can affect your mouth, nose, throat, eyes, and other areas as well.
