Anti-smoking groups around the globe are stepping up efforts to more strongly regulate cigarette packaging. Some are calling for bolder text warnings, others for generic packaging that would strip cartons of branding. And, last month, groups in New Zealand were victorious in prompting regulations that require all tobacco products manufactured for sale in that country to include explicit photos of diseased lungs, gangrenous toes and rotting gums and teeth. The move follows the lead of several countries around the world, including Canada, which already have the pictorial health warnings. Retailers in New Zealand have until August 28 to clear their inventory of the old packaging.
