About the Study : In this randomized clinical trial of 2 virtual culturally grounded interventions for substance use, virtual recruitment and intervention successfully reached urban American Indian or Alaska Native emerging adults with decreased access to resources. Both groups reduced consequences and cannabis use; however, only TACUNA participants reported decreases in quantity of alcohol and cannabis use and time spent around peers using cannabis and heroin and greater decreases in anxiety. These findings emphasize the role of bringing American Indian and Alaska Native emerging adults together to discuss ways to reduce alcohol and other drug use and socially connect with their tribal communities in the urban environment in a virtual setting.
