If you're trying to quit smoking or just want to shore up your body's defenses because you aren't planning to quit smoking, you might be checking out detoxify drinks and foods at this point.

Keep in mind that anything you drink isn't going to directly affect your lungs (you're kind of in big trouble if the drink goes there instead of your stomach), but you can choose healthy options that help your overall well-being.
