Substance-Related and Addictive Disorders

23 cases on alcohol, opioid, stimulant, tobacco, and cannabis use disorder pharmacotherapy, withdrawal management, and harm reduction — choose a case below to open its full multi-voice debate.

PsychiatrySubstance-Related and Addictive Disorders
Naltrexone vs. Acamprosate for Alcohol Use Disorder: Organ-Function-Driven Selection

A man newly diagnosed with compensated cirrhosis wants to start medication for alcohol use disorder today. The two first-line options split cleanly along organ clearance — but the drug that’s cleanest for his liver isn’t the one with the stronger trial result.

Case 0001
PsychiatrySubstance-Related and Addictive Disorders
Disulfiram Without Reliable Supervision: When a Deterrent Drug Needs a Witness

A patient specifically requests disulfiram and can explain exactly why she wants it. What she can’t yet offer is anyone to confirm she takes it during the hours she’s actually at risk — and the drug’s own founding trial says that gap matters.

Case 0002
PsychiatrySubstance-Related and Addictive Disorders
High-Dose Baclofen for Alcohol Use Disorder: Off-Label Use When First-Line Options Fail

A patient on stable long-term opioid therapy for chronic pain has already tried and lost access to both standard AUD medications. Baclofen’s French trial record is genuinely split — and his own regimen raises a risk neither trial was designed to test.

Case 0003
PsychiatrySubstance-Related and Addictive Disorders
Benzodiazepine Selection for Alcohol Withdrawal in Hepatic Impairment

Two patients in alcohol withdrawal share the same syndrome and nearly the same CIWA score. Only one of them has a liver that can safely clear the usual first-choice drug.

Case 0004
PsychiatrySubstance-Related and Addictive Disorders
Phenobarbital vs. Benzodiazepine-Based Alcohol Withdrawal Protocols: A Refractory Case

A patient in alcohol withdrawal has already crossed the threshold most definitions use for benzodiazepine-refractory disease. The question is whether to keep giving more of the same drug or add one that works by a different mechanism.

Case 0005
PsychiatrySubstance-Related and Addictive Disorders
Gabapentin for Alcohol Relapse Prevention in a Patient With a Gabapentinoid Misuse History

A woman in stable opioid-use-disorder remission wants to try gabapentin for persistent drinking. She’s also the one who brought up, unprompted, that she once misused that exact drug combined with an opioid.

Case 0006
PsychiatrySubstance-Related and Addictive Disorders
Methadone vs. Buprenorphine as First-Line Opioid Use Disorder Treatment

Two patients need medication for opioid use disorder. Neither choice is generically “better” — one man’s housing instability makes daily observed dosing the fix, while one woman’s inflexible job makes that same structure the obstacle.

Case 0007
PsychiatrySubstance-Related and Addictive Disorders
Buprenorphine Induction in the Fentanyl Era: Standard Wait vs. Low-Dose Micro-Induction

A patient has twice left treatment intake rather than wait through the withdrawal severity a standard buprenorphine induction requires. A newer, less-studied low-dose protocol is built for exactly this problem — but it is genuinely less proven.

Case 0008
PsychiatrySubstance-Related and Addictive Disorders
Extended-Release Naltrexone vs. Agonist Maintenance for Opioid Use Disorder

Two patients have both just completed detoxification. One’s history and support system make her a strong antagonist candidate; the other’s own account of four failed attempts points firmly the other way.

Case 0009
PsychiatrySubstance-Related and Addictive Disorders
Methadone Dosing for Opioid Use Disorder During Pregnancy

A pregnant patient stable on methadone for three years develops new withdrawal symptoms as her pregnancy advances — and fears the correct fix will hurt her baby, based on a belief the evidence doesn’t actually support.

Case 0010
PsychiatrySubstance-Related and Addictive Disorders
Continuing MOUD After a Relapse to Use While in Treatment

A patient stable on buprenorphine for over a year discloses, unprompted, a single use nine days ago. The question isn’t whether to punish it — it’s what an honest response to real risk looks like without discarding fourteen months of real progress.

Case 0011
PsychiatrySubstance-Related and Addictive Disorders
Expanded Buprenorphine Access After the 2023 X-Waiver Removal

A rural family physician can now legally prescribe buprenorphine for an established patient without ever holding a DATA-waiver. Whether she should start today turns out to be a different, harder question than whether she’s allowed to.

Case 0012
PsychiatrySubstance-Related and Addictive Disorders
Routine vs. Selective Naloxone Co-Prescribing for Chronic Opioid Therapy

A patient with eleven years of impeccable adherence hears her clinic’s new universal naloxone policy as a personal accusation. The policy may be sound population-level medicine and still land badly in a specific relationship.

Case 0013
PsychiatrySubstance-Related and Addictive Disorders
OTC Naloxone After 2023 FDA Approval: Does It Change Counseling Practice?

A worried mother buys naloxone off the shelf, no questions asked, exactly as the 2023 OTC approval intended — then walks up to the counter anyway because she has no idea how to use it.

Case 0014
PsychiatrySubstance-Related and Addictive Disorders
Managing Xylazine ("Tranq") Contamination in the Fentanyl Supply

A man’s unusually severe wound and unusually long, hard-to-rouse highs both point the same direction — a non-opioid sedative now widespread in the fentanyl supply that naloxone was never built to reverse.

Case 0015
PsychiatrySubstance-Related and Addictive Disorders
Clonidine/Lofexidine for Opioid Withdrawal in a Patient Declining Agonist Therapy

A patient with a firm career deadline explicitly declines methadone or buprenorphine and wants full detoxification instead. Respecting that choice still means being honest with her about what it actually risks.

Case 0016
PsychiatrySubstance-Related and Addictive Disorders
Pharmacotherapy for Stimulant Use Disorder: Appropriate When Nothing Is FDA-Approved?

A patient has made real progress in behavioral treatment for methamphetamine use disorder and then plateaued. No medication holds FDA approval for this disorder — but one off-label combination has real randomized trial evidence behind it.

Case 0017
PsychiatrySubstance-Related and Addictive Disorders
Varenicline vs. Combination NRT vs. Bupropion as First-Line Smoking Cessation

A motivated patient wants a direct recommendation, not a menu — and is nervous about a varenicline safety warning that was formally removed years ago after the very trial that answers her question.

Case 0018
PsychiatrySubstance-Related and Addictive Disorders
E-Cigarettes as a Cessation Harm-Reduction Tool vs. Youth-Vaping-Epidemic Concern

A middle school teacher who confiscates vapes from his own students daily wonders whether he should use one himself to finally quit smoking — after two evidence-based options already failed him.

Case 0019
PsychiatrySubstance-Related and Addictive Disorders
Pharmacotherapy for Cannabis Use Disorder: Off-Label NAC vs. Behavioral Treatment Alone

A patient plateaus on counseling and asks about a medication he read about online. The honest answer is that the drug’s best evidence comes from a population he no longer belongs to.

Case 0020
PsychiatrySubstance-Related and Addictive Disorders
Medical Cannabis Use With a Co-Occurring Cannabis Use Disorder

A veteran’s cannabis genuinely controls pain nothing else has. It has also, over the past year, become something his daughter no longer recognizes — and something he now meets structured criteria for a disorder around.

Case 0021
PsychiatrySubstance-Related and Addictive Disorders
Benzodiazepine Taper in Long-Term Prescribed Dependence: Direct vs. Cross-Taper

After eleven years on alprazolam prescribed for a real, understandable reason, a patient agrees to taper — and finds there’s no single agreed way to actually do it.

Case 0022
PsychiatrySubstance-Related and Addictive Disorders
Naltrexone for Gambling Disorder

A patient making real progress in behavioral treatment for gambling disorder plateaus on one specific symptom: an intense urge he describes as feeling just like the alcohol cravings his late father once described to him.
