Many characters in the game have an Addiction to either Cigarettes or Coffee.
Overview
While satisfying their addictions can help stave off depression or relieve them from it, not satisfying them has the opposite effect.
Smokers will consume 3 Cigarettes per day, and coffee drinkers will consume 1 Coffee and 1 Clean Water per day. The resources are automatically deducted from your inventory at the beginning of each day.
