Jesus! You people are pathetic! Read the labels!!! The Thai drink is mostly vitamins NOT CAFFENE, although it has some. SOLD AS REFRESHING VITAMIN DRINK The Carbonated version that is sold in the US is mostly carbonated water, sugar and caffene with most of the vitamins REmoved. SOLD AS ENERGY DRINK Get Real.... The Thai version is harmless, unless you drink so much you OD on Vitamins. And the US carbonated version would most likely send you into a caffene coma with carcinogens picked up during processing to kill you.
