I've been in AA for over 12 years, but also attended Alanon meetings because my AA sponsor started there to support a drug addicted best friend and I not only got a lot out of the meetings, but met some great experienced people there, male and female, old and very young, Alanon can be beneficial for anyone.
I don't know how they're handling meetings during this pandemic, but there are virtual meetings and phone meetings for most of the recovery organizations, so here's the website where you can learn what's happening in your area. As I said, I recommend it highly, it was one of the earliest recovery organizations and has helped so many for generations:
https://al-anon.org/
And here's the website for NA, Narcotics Anonymous, for your family members. That group also has meetings worldwide and I've met those in AA who are cross addicted and attend both AA and NA. But, as I've learned, you have to want it.
https://na.org/
And there is a DU Group which might be more appropriate for your questions, though I've been amazed since joining DU how many have embraced recovery or have had family members in need of help - as we've seen on this thread. It's a worldwide issue. Best of luck with this and please let us know how you're doing. 
Addiction & Recovery (Group)
