Morphology

smoking + one + own + dope

Literally the phrase is clearly compositional — ‘smoking’ + ‘one’s own’ + ‘dope’ will be read by a learner as inhaling their own drug — but the intended idiomatic sense of being self-defeating or falling victim to one’s own misguided ideas is a culture-specific, metaphorical extension that is not directly predictable from those constituents. A B1 learner who knows the words but has not encountered the expression is unlikely to infer the non-literal meaning, so the item functions as an opaque slang idiom.

Etymology

The idiom smoking one's own dope paints a clear picture: someone literally smoking their own dope and losing clear thinking. One popular idea is that this shows a person so taken by their own ideas that they hurt themselves, so the phrase means 'acting in a way that harms yourself' or 'believing your own praise'.
