Substance use disorder is a medical condition characterized by the recurrent use of drugs or alcohol despite negative consequences. It is diagnosed by a healthcare professional based on specific criteria laid out in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Some common symptoms of substance use disorder include cravings, withdrawal symptoms, inability to quit or cut back, using more than intended, neglecting responsibilities or obligations, and continued use despite negative consequences on personal or professional relationships, health, or finances. If you are concerned about your substance use, it’s important to seek professional help to assess and address any underlying issues.
