Black Black (Burakku Burakku) is a brand of caffeinated chewing gum produced in Japan by Lotte. It has been sold since 1983. and is popular in Japan, partially due to its well-known television commercials that star Jean-Claude Van Damme. It became popular in the United States after being mentioned in Wired Magazine. The gum's name is derived from its charcoal-like color. Ingredients include sugar, starch syrup, grape sugar, erythritol, oolong tea extract, ginkgo extract, chrysanthemum flower extract, gum base, flavorings, coloring agents (cacao, gardenia), caffeine, and nicotinamide. A persistent urban legend holds that the gum contains nicotine, the misconception stemming from confusion with nicotinamide, a different substance related to the B vitamins. The packaging contains some strangely phrased Engrish on the label that reads, "HI-TECHNICAL * EXCELLENT TASTE AND FLAVOR". Some sticks also say "YES, CHEWING!". In the United States, Black Black may be procured through a variety of mail order and online companies and in many Asian supermarkets.
