Gii'Igoshimong: Sitting With Your First Family

The goal of this randomized wait-list control study is to understand the relationship between ceremony and substance use (SU), SU risk (e.g., SU severity, depressive symptoms) and protective factors (e.g., spirituality, community support). The main questions it aims to answer are: * Will adults enrolled in Gii'igoshimong show improved SU outcomes compared to those in control groups? * Will self-relevant processing networks activated during stimulus engagement increase from pre- to post- engagement in ceremony and at 6-month follow-up? Researchers will compare adults that complete Gii'igoshimong with those that do not complete Gii'igoshimong to see if health outcomes are different. After completing baseline assessments, participants will be randomized to complete Gii'igoshimong now (intervention) or after the participants have completed the 1 month and 6-month post assessments (waitlist control). All participants (intervention and waitlist control) within a cohort will complete 1 month and 6 month post assessments at the same time.
