"Caffeine is an addictive drug, affecting 90% of all Americans, which alters the brain's natural state, and stimulates it in a manner similar to the amphetamines cocaine and heroin.

The mechanisms employed by caffeine, cocaine, and heroin, are to close blood vessels in the brain, so the brain and body cannot sleep, to cause the release of adrenaline into the body, so the body remains active and alert, and to manipulate dopamine production in the brain, so the person experiences a temporary "high."

One final mechanism caffeine, cocaine, and heroin share, is their ability to manipulate dopamine production. Dopamine, a neurotransmitter, activates the "pleasure centers" in certain parts of the brain, and simply makes a person feel good. Naturally, the pleasurable effect produced by dopamine manipulation plays a prominent role in caffeine addiction."
