Are Tobacco Warning Labels Effective? Several countries around the world, including
Canada, have pictures on their tobacco products. Despite the efforts of the FDA, the tobacco
companies in America are not required to put pictures on their products.
Do you think that tobacco companies should be required to put pictures on their labels?
Write a paragraph explaining why or why not. Or design a label you think will convince people to stop smoking.
