x1 (user/consumer) is an addict of/is addicted to substance/entity/experience x2 by standard x3

Implies physiological need; the nature of x2 does not matter, only the response of x1. Quite arguably, anything other than an experience filling in x2 is sumti-raising. Is not necessarily bad; for example, one can be addicted to life, or to the consumption and processing of sugar.
