The resource explains the DSM-5 criteria for substance use disorder severity, screening tools such as CRAFFT for adolescents, and the pharmacology of mu opioid receptor antagonists (naloxone, naltrexone), partial opioid agonists (buprenorphine), amphetamines, and cannabis. It also covers neurobiological theories of addiction, cross-tolerance, detoxification principles, withdrawal syndromes, fetal alcohol syndrome (FAS) features, and therapeutic approaches for patients with FAS. Designed for students in Psychiatric Nursing, Mental Health Nursing, Nurse Practitioner Programs, Addiction Medicine, and Behavioral Health Studies, this guide is also valuable for NCLEX-RN/PN candidates, psychiatric nurse practitioners, addiction counselors, and clinicians managing substance use and comorbid mental health conditions. The structured Q&A format ensures efficient revision, rapid recall, and application-ready knowledge for both academic success and clinical excellence.
