Addiction-induced psychopathology refers to the mental health issues that arise as a direct result of substance use disorders. Chronic drug or alcohol use can lead to cognitive impairments, psychosis, anxiety, depression, and personality disorders. Prolonged substance abuse disrupts brain chemistry and structure, leading to persistent changes in cognition and emotional regulation. These alterations can manifest as psychiatric symptoms that may mimic other mental health conditions, making it essential for clinicians to carefully distinguish between primary psychiatric disorders and those induced by addiction. Effective treatment involves a dual approach, addressing both the psychiatric symptoms and the substance use disorder.
