Drug economy version 1.2 — 20 October 2026
We have removed the wider arithmetic stress range from the summary and current scenario table while seeking clarification of the aggregate uncertainty margin published in the Home Office’s proceeds-of-crime study. The source figures remain unchanged. CLA’s UK extrapolations remain conditional illustrations. We have clarified which calculations can be reproduced from public information; the available evidence still does not establish a complete, consistently measured UK total.
This release revises the drugs-economy material only. The other five datasets remain at version 1.1.
