This clinical commentary uses a prenatal-care case to explain how family physicians can identify and treat substance use disorders during pregnancy. It recommends universal, nonjudgmental screening, obtaining consent before toxicology testing, and using person-first language and motivational interviewing. For opioid use disorder, the author emphasizes treatment with buprenorphine or methadone rather than withdrawal management, along with overdose-prevention education and naloxone access. The article also recommends coordination with behavioral health, peer support, and community services and preparation for newborn care. It is a practice-focused commentary, not an original clinical trial.
