Coffee: Drug or Not?

"Coffee: Drug or Not?" was adapted from a commentary originally produced for Medicine Chest, a radio program produced by the Higuchi Biosciences Center and the Drug Information Center at the University of Kansas.

Is coffee a drug? Actually, no. But the morning go-getter and after-dinner picker-upper contains one: caffeine. Caffeine occurs naturally in the leaves, seeds and fruits of more than 60 plants, including coffee, tea leaves, kola nuts and cocoa beans. Caffeine narrows blood vessels in the brain and stimulates the cerebral cortex, the brain's outer sheath. This helps you think more rapidly and clearly. Elsewhere in the body, blood vessels expand. Coordination improves. Caffeine is used medically as a mild stimulant or headache-killer. Caffeine citrate helps in treating sleeping problems in newborns. If you think early morning fatigue is a disease, nobody's going to stop you from taking your medicine!
