I wandered over to Amber's instagram (slow work day...) and her bio says "Life is great sober and healthy", but doesn't she still drink? I guess if she no longer takes drugs she can call herself clean, though some may disagree, but sober? The definition of sober is to do with alcohol.
Also I've only just started following OG and one of the things that irritates me most is Amber's pet name for Leah, not once have I heard her acknowledge her child's actual name. "Hey BewBew!!!" is like nails on a chalkboard to me.
