This book presents an interdisciplinary analysis of addiction as a complex biopsychosocial and ethical phenomenon. Rejecting reductionist medical or moral views, it interprets addiction as a reflection of human vulnerability, social fragmentation, and moral neglect. The author classifies addictions into substance-based and behavioral forms, exploring their individual, familial, and societal consequences. The work highlights addiction's ethical dimensions, autonomy, dignity, and justice, while emphasizing gender, cultural, and policy implications. Prevention is framed as an ethical and structural responsibility grounded in education, community engagement, and public health. Drawing from philosophy, theology, and international frameworks such as WHO and UNODC, the author calls for a restorative, dignity-centered approach that prioritizes compassion, solidarity, and systemic reform.
