Substance Use Disorder Supportive Care Protocol

Substance use disorder (SUD) is a medical condition characterized by compulsive use of substances (alcohol, drugs) despite harmful consequences. It affects brain circuits involved in reward, stress, and self-control. Recovery is possible with proper treatment, and many people achieve long-term sobriety.

CRITICAL: Substance use disorders require professional treatment. This protocol is SUPPORTIVE, not a replacement for evidence-based treatment including:

•Medical detoxification: Withdrawal from alcohol, opioids, or benzodiazepines can be life-threatening - never stop suddenly without medical supervision

•Medication-assisted treatment (MAT): Naltrexone, buprenorphine, methadone, acamprosate, disulfiram - these save lives

•Behavioral therapies: CBT, motivational interviewing, 12-step programs, contingency management

•Treatment of co-occurring mental health conditions: Depression, anxiety, PTSD common

* N-Acetyl Cysteine (NAC) is one of the most studied supplements for addiction. It modulates glutamate, a neurotransmitter involved in craving and reward. Studies show benefit for cocaine, cannabis, nicotine, and gambling disorders.

* B Vitamins, especially thiamine (B1), are critical. Alcohol depletes B vitamins and can cause Wernicke-Korsakoff syndrome (permanent brain damage) if thiamine is not replaced. Anyone with alcohol use history should take thiamine.

* Omega-3 Fatty Acids support brain health and may help with impulsivity and mood during recovery.

* Milk Thistle protects the liver, which is often damaged by alcohol and drugs.

* Magnesium helps with anxiety and sleep - common challenges in early recovery.

Expected timeline: Early recovery is challenging. Supplements support overall health but cravings typically decrease over months with proper treatment. Full neurological recovery can take 1-2 years.

Clinical Perspective

Substance Use Disorder: DSM-5 criteria include impaired control, social impairment, risky use, pharmacological criteria (tolerance, withdrawal). Severity: mild (2-3 criteria), moderate (4-5), severe (6+). Neurobiology: dysregulation of dopamine reward pathway, stress systems (HPA axis, CRF), prefrontal cortical control. Chronic changes in brain structure and function require extended recovery period.

CRITICAL: Medical treatment is primary. Detoxification: alcohol/benzo withdrawal can be fatal (seizures, delirium tremens) - requires medical management; opioid withdrawal uncomfortable but rarely fatal (except dehydration). MAT: buprenorphine/methadone for opioid use disorder (OUD) - reduces mortality 50%+; naltrexone for OUD and AUD; acamprosate for AUD; disulfiram for AUD. Behavioral: CBT, contingency management, 12-step facilitation. Co-occurring disorders: 50%+ have comorbid psychiatric conditions - must treat both. Supplements are ADJUNCTIVE.

* N-Acetyl Cysteine (A-grade): Glutamate modulation; reduces cravings. Meta-analysis: (PMID: 25556664). RCT: cocaine (PMID: 28472867). 1200-2400mg daily. Best evidence for cocaine and cannabis.

* Omega-3 Fatty Acids (B-grade): Brain health; dopamine function. Review: (PMID: 27230032). Trial: (PMID: 28551820). 2-4g EPA+DHA daily.

* Vitamin D (B-grade): Common deficiency; mood. Review: (PMID: 27856395). 2000-4000 IU daily; test levels.

* B-Complex/Thiamine (A-grade): CRITICAL for alcohol use - prevent Wernicke. Guidelines: (PMID: 28245943). Thiamine 100mg+ daily for AUD; give before glucose.

* Magnesium (B-grade): GABA; anxiety; sleep. Systematic review: (PMID: 28445426). 300-400mg daily. Often depleted.

* Zinc (C-grade): Immune; neurotransmitters. Study: (PMID: 26845419). 15-30mg daily.

* L-Glutamine (C-grade): Craving reduction. Pilot: (PMID: 10836135). 5-10g daily.

* Vitamin C (C-grade): Antioxidant; withdrawal. Study: opioid withdrawal (PMID: 10878763). 1000-2000mg daily.

* Milk Thistle (B-grade): Hepatoprotection. Cochrane: (PMID: 28248976). 420mg silymarin daily.

* Probiotics (C-grade): Gut-brain axis. Review: (PMID: 29882905). 10-20 billion CFU daily.

Assessment targets: Substance use history, withdrawal risk, liver function, vitamin levels (especially B1, D, B12), psychiatric comorbidity, infectious disease screening (HCV, HIV), social support.

Protocol notes: Thiamine: give BEFORE glucose in alcohol users (glucose precipitates Wernicke in B1-deficient); 100-500mg IV/IM in acute setting, then oral. Nutritional deficiencies: multiple deficiencies common; consider comprehensive labs and repletion. Liver function: monitor ALT, AST, GGT; may limit supplement metabolism. Drug interactions: check interactions with MAT and psychiatric medications. NAC timing: may take 4-8 weeks to see craving reduction; best studied adjunct to behavioral treatment. Sleep: common early recovery problem; magnesium, good sleep hygiene; avoid benzodiazepines (addiction liability). Exercise: evidence supports as adjunct treatment - improves mood, sleep, reduces cravings. Social support: critical predictor of success; 12-step programs, SMART Recovery, peer support. Relapse: part of chronic disease; not failure - opportunity to adjust treatment. PAWS (Post-Acute Withdrawal Syndrome): mood/cognitive symptoms lasting months; supplements may help; requires patience.
