Exploring the scope and impact of substance abuse, this content delves into the biological factors contributing to addiction, including genetic predispositions and neurodevelopmental factors. It examines the intersection of mental health and substance use disorders, highlighting the role of the nucleus accumbens and orbitofrontal cortex in the brain's reward system and decision-making processes, and how these are affected by chronic drug use.
