Abstract : The association between substance use disorder (SUD) and persistent cravings, emotional distress, relapse risk, and disrupted sleep has a negative impact on rehabilitation outcomes. The aim of this systematic review was to investigate whether mindfulness-based meditation interventions produce beneficial effects in substance users with sleep disturbances and substance cravings. Using Scopus, Web of Science, PubMed, ScienceDirect, Google Scholar and Emerald Insight, the literature from these sources was retrieved in accordance with PRISMA 2020 guidelines. Forty of the eligible studies were included in the qualitative synthesis. The results showed that the mindfulness-based interventions (MBIs) – including Mindfulness Based Relapse Prevention (MBRP), Mindfulness Based Stress Reduction (MBSR), mindfulness meditation, qigong meditation and Mind–Body Bridging (MBB) – were associated with decreased cravings, stress, anxiety, and relapse risk; increased emotional regulation; enhanced psychological well-being; and improved sleep quality. Additionally, a methodological review of the literature indicated methodological weaknesses such as the lack of consistency in intervention procedures and the limited number of long-term follow-up studies.
