Definitely. A lot of areas I've noticed don't have as much face to face support for families and friends of addicts. In Chicago (I may be wrong, this is just what I know from their website) there's only one Nar-Anon meeting a week- compared to maybe 50+ NA meetings.
Sometimes I visit an online Nar-Anon group (it helps keep me from killing addicts I have to work with and also look some at my past interactions within my family.)
Happy to pass that along if you want, let me know.
