Verified step by step guidance

1. Understand that the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, 5th Edition) uses the term 'substance use disorder' rather than 'drug addiction' as a clinical diagnosis.
2. Recognize that substance use disorder is characterized by a pattern of compulsive drug seeking and use despite harmful consequences, which is a key diagnostic criterion.
3. Note that physical withdrawal symptoms are not required for a diagnosis; the disorder can be diagnosed based on behavioral and psychological criteria alone.
4. Understand that substance use disorder can be diagnosed for both legal and illegal substances, so the legality of the substance is not a determining factor.
5. Acknowledge that substance use disorder is classified as a mental health disorder in clinical settings, reflecting its psychological and behavioral components.
