What is Substance Use Disorder?Diagnosis

Substance Use Disorder (SUD) is a chronic, treatable medical condition characterized by an inability to control use of a substance despite harmful consequences. It is a brain disorder involving the reward system, impulse control, and stress circuits — not a moral failing. About 48 million Americans meet criteria for SUD in a given year. Effective treatments exist — including FDA-approved medications for alcohol, opioid, and tobacco use disorders that cut mortality by 50%+ — yet most people who could benefit never receive them.

• Opioid Use Disorder (OUD) — Buprenorphine, methadone, naltrexone (extended-release injection — Vivitrol). MOUD reduces overdose deaths by 50%+. Office-based buprenorphine is now widely available without an X-waiver.
• Alcohol Use Disorder (AUD) — Naltrexone (oral or injection); acamprosate; disulfiram; topiramate / gabapentin off-label. Counseling + peer support (AA, SMART Recovery, Refuge Recovery, others).
• Tobacco Use Disorder — Varenicline (most effective single agent); bupropion; nicotine replacement (patch + gum/lozenge combination); behavioral counseling; quit-line (1-800-QUIT-NOW).
• Stimulants (cocaine, meth) — No FDA-approved meds; CBT + contingency management most effective behavioral; some emerging pharmacotherapies (mirtazapine, naltrexone-bupropion).
• Cannabis — CBT; motivational enhancement therapy; no FDA-approved meds; growing recognition of cannabis use disorder + cannabinoid hyperemesis syndrome.
• Naloxone (Narcan) for overdose reversal — Now available over-the-counter without prescription. Every household, workplace, and venue should have it.

Naloxone everywhere + medication-assisted treatment is the modern playbookKnow your plan

Two changes have rewritten OUD care: naloxone is now over-the-counter (carry it, use it, save lives), and buprenorphine prescribing no longer requires the old X-waiver. The bottleneck is not science — it is access and stigma.

• Naloxone (Narcan, Kloxxado, generic) at home, in your car, at work — opioid overdose can happen to anyone using opioids (prescription or illicit).
• If you have OUD — start MOUD with buprenorphine, methadone, or naltrexone. The science is clear: medication saves lives.
• Address fentanyl + xylazine — modern illicit supply means even occasional use is high-risk; never use alone; test strips; have naloxone on hand.
• Tell every clinician — affects pain management, anesthesia, prescribing decisions, infection screening (HIV, HCV).
• Hepatitis C cure + HIV care — both common in SUD; both curable/manageable; ask for testing.
• Family + community recovery support — AA, NA, SMART Recovery, peer recovery coaching, Al-Anon for family.

Your daily Force FieldLive It

• Take MAT/MOUD daily as prescribed — buprenorphine, methadone, naltrexone; do not skip; tell every prescriber.
• Naloxone at home, in your car, in bag — train family + close contacts.
• Recovery support — weekly minimum — AA, SMART, peer recovery coach, therapy, group treatment.
• Identify triggers + relapse signals — written plan; reach out before, not after.
• HIV + HCV + STI + TB screening — HCV is curable; HIV is manageable; ask for testing.
• Vaccinations — flu, COVID, pneumococcal, hepatitis A + B (if not immune).
• Mental health — depression, anxiety, PTSD overlap with SUD; treat them.
• Sleep, nutrition, exercise — all support recovery; address with structure.
• Pain management plan if chronic pain — non-opioid first; multimodal; coordinated with addiction medicine.
• Pregnancy + SUD — buprenorphine and methadone safe (and recommended) in pregnancy; specialty co-management.
• If overdose occurs — naloxone + 911 + rescue breathing + recovery position; debrief with team afterward.

Red flags — call nowAction

• Call your clinic the same day for: new chest discomfort with exertion that goes away with rest (stable distress worth evaluating); a missed dose of antiplatelet or mental health medication; medication side effects (muscle aches, bleeding, GI symptoms).
• Bring up at next visit: any change in exercise tolerance, lipid follow-up timing, BP log review, smoking-cessation support, depression screening, sleep concerns.
