A lot of addiction has to do with substances and activities that are designed for rapid delivery and convenience. It is a little more difficult to become addicted to something you are growing yourself, and harvesting yourself, and processing and curing yourself.
It takes quite a bit of work to do this, and the work itself is pleasurable and fulfilling on top of everything else, whereas it is typical for an addiction to supply quick hits of pleasure and fulfillment wherever it is sorely lacking.
Quick hits are rapidly metabolized, and so exhausted, and then more is needed, deepening those channels to be hit.
Much in this society is designed for rapid delivery and rapid distribution, and this is not an accident. And so the quick hits are quickly metabolized, creating bigger and more urgent spaces of lack, drawing in bigger and bigger hits, and constant acceleration is required.
Generalized, there is addiction everywhere. Part of society's function is to cordon off the aspects of this which are a threat to its powerful. And so the designation of "addiction" applies to those substances and activities the powerful do not like. "Illegal drugs" for example are substances which the establishment doesn't have a monopoly on, mainly because their effects are too destructive either to the existing social arrangements or to labor, whose production are taken up by fringe elements looking for their own power.
This is not pure caprice, as the powerful stay powerful by maintaining what living tissue is required to indulge them. But a society such as this is in a constant state of degeneration, which is arguably accelerating far past what degeneration is native to life's elemental processes.
