Objective: Substance use disorder (SUD) is an epidemic in the United States. Current standard of care for SUD continues to produce a 40-60% relapse rate. Treatment for SUD is costly and is not obtainable for many individuals. The purpose of this project is to implement mindfulness as an adjunct treatment for SUD to reduce relapse. Methods: Voluntary program offered at a residential treatment center designed as a team-based project. The combined project includes exercise, wellness, and mindfulness. Adults over the age of 18, male or female with a diagnosis of SUD were eligible. Program consisted of three hourly sessions a week, for a total of three weeks. Sessions included one session of exercise and wellness, one session of mindfulness training, and a combined session. Mindfulness sessions included learning the seven pillars of mindfulness followed by guided meditation. Participants were given a mindfulness journal for daily exercises. Five Facet Mindfulness Questionnaire (FFMQ) was completed before program and on completion. Results: 11 of 22 participants completed the program. FFMQ total scores were analyzed with paired t-test with Wilcoxon signed rank to account for small sample size. Statistical significance was based on an alpha of 0.05, V=10.50, z=2.00 and p=0.45. Conclusion: This project has the potential to decrease relapse rates by increasing mindfulness in individuals with SUD. Mindfulness training reduces cravings and negative thought processes. Implementing mindfulness training with current standard of care can be cost effective and recommended for all individuals with SUD.
