Cigarette packs have long served as portable advertising for tobacco companies, with smokers conveniently disseminating branding and imagery wherever they go, writes Vox Science and Health. Packaging has also long been a central target for health advocates in the global effort to get more people off deadly tobacco products. Last week, the World Health Organization called on countries everywhere to step up the war on tobacco advertising and promotion by introducing plain, or standardized, packaging of tobacco products. Notably, the United States isn’t even close to getting plain packaging on cigarettes anytime soon.
