Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are Ojibwe/Anishinaabe adults age 18 or older who self-report using any substances in the past 30 days and who do not have pregnancy, a seizure disorder, Type 2 diabetes, or a history of head injury with loss of consciousness.
✕Probably not a fit
People who are under 18, do not self-identify as Ojibwe/Anishinaabe, have not used substances in the past 30 days, are pregnant, have a seizure disorder, Type 2 diabetes, or a history of head injury with loss of consciousness may not be eligible and are less likely to benefit from this intervention.

What this trial studies
The project uses a community-based participatory randomized wait-list control design enrolling about 300 Ojibwe/Anishinaabe adults who report substance use in the past 30 days. After baseline assessments, participants are randomized to attend an up-to four-day Gii'igoshimong ceremony immediately or to a wait-list control who attend after 1- and 6-month follow-ups, with all cohorts completing baseline, 1-month, and 6-month assessments. Outcomes include substance use behaviors, depressive symptoms, measures of spirituality and community support, and neurocognitive measures of self-relevant processing before and after ceremony. The study will also create and evaluate implementation strategies to support long-term community sustainment of the ceremonial practice.
Why it matters
Potential benefit: If successful, participating individuals could experience reduced substance use, fewer depressive symptoms, and stronger protective factors like spirituality and community support.
How similar studies have gone: Observational and community-based work suggests traditional ceremonial practices can protect against substance use, but randomized controlled trials testing these ceremonies are limited.
