The same general issues apply for non-substance and for substance addictions. The first chapter in The Meaning of Addiction begins with a description of TV addiction. Why does a child become drawn into television viewing and isolated from external experiences? TV addiction has the same interactive nature as other addictions -- failure at external exposures (real-world interactions) and the need for comfort and reassurance of a safer alternative (the TV). In other words, no addiction can be described simply by the object of the addiction without directly relating the environment of the addict.
