Beginning Wednesday, smokers in the UK will be greeted with a new warning that they won't be able to ignore. A graphic new advertising campaign featuring gruesome pictures of late-stage throat cancer patients shows that the same fate may await them if they continue to indulge in their habit.

The photos will be added to cigarette packs in addition to the standard written warnings such as, "Smoking clogs the arteries and causes heart attacks and strokes." The images will be mandatory on all cigarette packs by October 2009, and all tobacco products by 2010.

The ad campaign is the latest in a series of steps by the British government to halt tobacco use in their country, where stats show that one in six people smoke. Written warnings on packages were adopted in 2003, and smoking was banned in public places in 2007.
