I. Abstract
Diacetylmorphine opioid prodrug included to test therapeutic, psychoactive, toxicity, dependence, and withdrawal effect roles in the evidence graph.
Clinical Summary
Primary Efficacy
- — Heroin is represented as a potent opioid analgesic through active morphine metabolite signaling.
Key Cautions
- — Dose-dependent respiratory depression is the central acute toxicity concern.
- — Repeated exposure carries high dependence and withdrawal liability.

AnalgesiaTHERAPEUTIC
Diacetylmorphine is modeled as producing opioid analgesia through active morphine metabolites and opioid-system activation.
Evidence: High·Magnitude: High
EuphoriaContextual
Euphoria is represented as a sought psychoactive effect in nonmedical contexts and a reinforcement signal relevant to misuse liability.
Evidence: High·Magnitude: High
Respiratory DepressionToxicity
Dose-dependent respiratory depression is the central acute toxicity concern for heroin and other potent opioids.
Evidence: High·Magnitude: High
Dependence LiabilityAdverse
Repeated exposure carries high dependence liability through opioid reinforcement, tolerance, and withdrawal dynamics.
Evidence: High·Magnitude: High
Withdrawal SyndromeWithdrawal
Withdrawal syndrome is represented as a discontinuation-context effect after dependence, not an acute desired pharmacological effect.
Evidence: High·Magnitude: Moderate
PSYCHOACTIVEContextual
Euphoria
Euphoria is represented as a sought psychoactive effect in nonmedical contexts and a reinforcement signal relevant to misuse liability.
