Jolt gum contains caffeine, plus guarana, plus ginseng - and two pieces of the gum amounts to the same caffeine as an average cup of coffee.
Currently there are two flavors - spearmint and icy mint. Jolt Gum is made by the same people that bought us Jolt Cola.
NOTE: While Jolt Gum claim that the two pieces have "as much caffeine in a cup of coffee" -- a lab test proved otherwise. See Sources below.
