All of these substances are highly addictive. Alcohol just happened to be the one I got addicted to. Probably because it was legal, easily available and not only socially acceptable but encouraged. It might as well have been anything, as there but for the Grace of God go I. Go all of us.
It is all the same. Keep on any of these addiction roads and they will all lead to hell.
I have to wonder if allowing yourself to dwell and split hairs about this, if you are finding a way to keep your high alive? Might there be a question beneath your surface inquiry that would help you and others gain greater detachment, and not promote attachment?
