Those that smoke or use tobacco know the harmful effects. It has been mentioned over and over and still people continue smoking. On the outside of the boxes of cigarettes in the United Stated they say that smoking kills but in Brazil where I was visiting recently they use pictures. After all a picture speaks a thousand words. This is a picture chosen by the department of health and placed on the back of each pack of cigarettes. Each picture is different.
To your health,
