Project Brothers reclaiming Emotional Awareness, tranquility, Healing, and Ex-istence (BrEAtHe) is a research study to create a program focused on mindfulness and stress reduction specifically tailored to young adult Black males (18 to 29 years old) residing in Durham, NC and in Hartford, CT. The investigators plan to use a mobile app on a cell phone to better understand 'real-time' feedback of experiences of stress due to racism. The investigators are interested in learning about the recruitment and retention of Black males participating in mindfulness based practices. The investigators are also interested in receiving feedback about options to modify and scale a Mindfulness Based Stress Reduction intervention and its preliminary effects on reducing physical and emotional stress reactions and poor coping mechanisms like marijuana and alcohol use linked to everyday racism and discrimination.
