Addicted is formed from "ad-" (meaning to or towards) and "dicere" (meaning to say or declare). The word originally described a state of being bound or devoted to something, as if one has declared allegiance to it.
Think of being 'towards' ('ad-') something you have 'declared' ('dicere') your loyalty to — that's why addicted means being devoted to a habit or substance.
