Not only does smoking increase your chances of lung cancer, it also weakens your immune system. There are thousands of toxins present in cigarette smoke that can affect the immune cells in the body by either impairing their proper function, or altering your immune cell count.

If you smoke and you are looking for a way to strengthen your immune system to avoid these problems, then you should quit smoking immediately.
