"for codies our DOC is the A"
I would point out that beyond the chaos caused by alcohol in the family (social) system, many of the issues described on the friends and family forum relate to emeshment and boundry issues; issues, that is, which transend alcohol use. An extream hostilty that is sometimes aimed at "those alcoholics," as a group, is matched by efforts at ingroup exclusivity (the use of specialized abbreviations for example) and inaccurate assumptions about similarities among percieved peers--a form of all-or-nothing thinking that can encourage emotional extreams.
These are issues that can coexsist with, but are different from, dealing with alcohol or drug use/abuse by loved ones.
