Section B — Supplemental Toxicology
The initial toxicology report estimated the Alprazolam ingestion window as 20:30–22:30 (± 30 min). Supplemental gastric analysis has refined this estimate. Gastric pH and absorption markers are consistent with ingestion on a post-meal, semi-empty stomach (food confirmed as 2–3 hours prior). Alprazolam onset under these conditions is typically 30–45 minutes post-ingestion (faster than the standard 60–90 minute fasted-state model used in the initial calculation).
ModelIngestion Window
Initial estimate (standard model)20:30 – 22:30
Refined estimate (supplemental — post-meal absorption)21:50 – 22:20
Margin of error (refined)± 15 minutes
Analyst Note
The refined ingestion window (21:50–22:20) is narrower than the initial estimate. The earlier window should be treated as superseded by this report for the purposes of the investigation. Further refinement is not possible from available samples.
