How long does caffeine remain in your body?

The time it takes for the body to eliminate one half of a caffeine dose is normally between 3 to 12 hours. It is called the half-life of caffeine. Several factors can shorten or lengthen the half life of caffeine. Smoking, medications and diseases are some factors. Pregnant women have higher caffeine half-life, 18 to 20 hours - pretty much longer for the fetus since its organs are not yet fully formed to be able to eliminate caffeine easily. About 99% of the elimination process takes place in the liver.
