I'm not an addict but my husband is and I have been to many meetings with him............both AA and NA, as well as celebrate recovery (christian based step program)'
any and all would work ---the main thing is for him to go, and keep trying different ones till he finds the ones he really likes.
At his age.........I would also like to mention that our area has "group therapy" out patient meetings that have more----young adults that may be something he could check into as well
good luck, his committment to 90- meetings 90 days is great
