And it's a mental health condition, that lights up like a christmas tree in MRI scans and screams, "I'm an addict!". None of that is human nature, as evidenced by the fact that very few people are alcohol or other drug addicts. But without reading the rest of the context, it's hard to say what the author really meant.
