heroin

Diacetylmorphine referent

The identity record should resolve the heroin name to diacetylmorphine and explicitly distinguish related compounds.

1. Which authoritative chemical record establishes the identifiers and synonym relationship for heroin, diamorphine and diacetylmorphine? definition
2. What evidence distinguishes the identified substance from morphine, monoacetylmorphine or another opioid? boundary

Form-specific identity

A salt designation, pharmaceutical label or illicit-market name carries different identity claims that require separate evidence.

1. Is the material identified as heroin free base, a specified salt or an unresolved form? definition
2. Does the name describe an analytically identified substance, a documented medicine or merely a claim about the material? provenance

Method-bounded confirmation

Identification conclusions should retain the method, reference evidence and limitations that support them.

1. Which analytical method and reference material support identifying heroin in this sample? provenance
2. Can the method distinguish heroin from relevant related compounds, and what detection limits or interferences apply? measurement

Composition with explicit basis

Quantitative results should specify their chemical basis and distinguish detected constituents from substances outside the test scope.

1. What heroin content was measured, with which units, uncertainty and free-base or salt reporting basis? measurement
2. Which additional opioids, adulterants, excipients or impurities were tested for, detected or left unassessed? measurement

Condition evidence

Storage history and observations should be recorded separately from analytically established degradation or contamination.

1. What packaging, storage history, moisture exposure and visible condition are documented for this material? provenance
2. What analytical evidence supports degradation or contamination, and can it distinguish change over time from the original composition? measurement

Representative heroin content

A tested portion should not automatically establish the composition of every portion in a heroin-containing mixture.

1. Which portion or package was sampled, and what sampling record connects it to the material under assessment? provenance
2. What evidence supports extending its heroin and co-occurring-substance results to the remaining material? boundary

Substance and mixture hazards

Hazard records should cite applicable evidence and retain uncertainty about uncharacterized constituents.

1. Which authoritative hazard references apply to the identified heroin form and detected co-occurring substances? provenance
2. Which composition uncertainties prevent a sufficiently supported assessment of the proposed handling activity? boundary

Handling and escalation

The model should support referral to applicable procedures without supplying dosing or administration instructions.

1. Which approved procedure governs containment, laboratory examination or disposal of this heroin-containing material? action
2. What evidence of compromised containment or suspected exposure requires stopping the activity and invoking the relevant emergency procedure? action

Traceable diamorphine material

Product and custody records should establish which claims attach to the material and which remain unverified.

1. Which supplier, manufacturer, lot and custody records connect the material to its claimed origin? provenance
2. If pharmaceutical status is claimed, which product authorization and quality records support that claim for this specific material? provenance

Activity-specific control

Legal classification and authorization should be tied to a jurisdiction, effective date, actor and activity.

1. Which current legal source classifies heroin or diamorphine in the relevant jurisdiction, including applicable preparations or exceptions? provenance
2. What authorization and records are required for the proposed possession, testing, transfer or disposal? action
