White Bison is a wonderful group. They have a book with meditations for each day and you can sign up to receive the meditations in email every day (free). Similar to other organizations focused on helping people in recovery but from a Native perspective instead of the colonized/settlers religions. I think the meditations are useful and beautiful for everyone, not just those who might need them most. But if you know someone with problems with addiction their book might be the perfect gift to gently encourage them toward healing.
