Many people know that caffeine is a natural drug that is present in the leaves, beans and nuts of various different plants. Caffeine reactions vary between people, but usually it helps to speed up the brain and nervous system as caffeine is a stimulant. While caffeine is typically safe for human consumption, it is not always recommended to have large quantities during pregnancy and breastfeeding or when a person has health issues such as heart related illnesses, or anxiety. Certain tastes like tea and coffee are available in decaf (short for decaffeinated) form, where there is much less caffeine available as it has been removed.
