Coffee or tea, anyone? They might be two of our favourite drinks, but how many of us know exactly what caffeine â the drug behind the world's most consumed beverages (except for water) â is up to in the body? Caffeine, like nicotine, is legal, and, if not addictive, it's definitely habit-forming. Caffeine is found in a number of plants: tea, coffee beans, guarana berries and cocoa nuts (although the quantity is quite small, around 0.2-0.4 per cent), where it acts as a toxin to defend against herbivores.
