Everyone is addicted to food. Most people are addicted to food substances that are completely non-essential, such as sugar, salt, butter and caffeine. In places where drugs aren't available people get addicted to certain spices to a point where they feel hungry if their daily intake lacks a certain spice.

Some people get addicted to exercise. They feel incomplete if they can't do their nightly run. Exercise alters your internal chemical composition. Just like food and other ingested substances. And coffee, mountain dew, beer, rum, mojito, etc. In the case of some of these its an extreme mix of all sugar, caffeine and alcohol - think JD and Coke.
