Warning labels can be useful, but they are rarely read. There are two general types of warning labels: Those that caution against unsafe use or operation of a product, and those that caution against using a product at all. When it comes to the latter type, let’s face it, most warning labels don’t work. You usually find them on things that the person thinking of using the thing already knows is dangerous anyway. If they realize this ahead of time, then why is a little label going to dissuade them at the last minute? One important exception to this rule seems to be the graphic warning labels that have surfaced on packs of cigarettes in many countries.
The graphic warning labels are a practical expression of the fact that a picture is worth a thousand words. Describing with text that smoking a cigarette can give you cancer or emphysema is nothing compared to showing a picture of a cancerous organ or a lung that is taken from someone who had suffered from emphysema. These labels do have text too, but they back it up by showing rather than only telling. Over 70 countries around the world require these labels on packs of cigarettes. Some Folks at Anastasia Date (googleplay) agree that the United States should follow suit immediately. Stopping people from picking up this one habit and helping motivate those who already have the habit to quit will put a bigger dent in health care costs than any other change that can be undertaken.
