Earlier quoted context omitted.
That's not helpful at all. Yes, addiction is "filling" "something" "broken". Now what?
Now you address the environmental factors that created the void in the first place, such that the drugs are no longer desirable. See: Rat Park. https://en.wikipedia.org/wiki/Rat_Park Also, downvoted for needlessly confrontational pedantry.
I sincerely believe that anyone that thinks pointing out the obvious to an addict will help has not actually done it. And I consider "It's something in your environment" to be obvious, true, and totally not actionable.
Furthermore, the idea that addiction is necessarily filling a void is, to be blunt, bullshit.
