The technical paper published in March 2008 identified inadequate monitoring as a barrier to understanding the full scale of the problem. It brought together information on substances, evidence and responses, arguing for better monitoring before drawing broad conclusions.
What is measured shapes the interpretation
A systematic review by Beynon and colleagues, also published in 2008, examined studies of substances in alleged drug-facilitated sexual assault. It identified difficulties separating covert administration from voluntary consumption when interpreting findings.
The editorial implication matters: detecting a substance, recording a suspicion and establishing that someone administered it without consent are not interchangeable claims. Each requires a different kind of evidence.
Reading an archive without treating it as current data
These publications suggest useful questions for reading a news story: which population was studied, what period was covered, how the data was collected and what limitations the authors acknowledged. An isolated number cannot answer those questions.
We retain this piece to support critical reading. Its percentages are not extrapolated to today’s population or used to claim a particular current frequency of spiking.
Context matters
Both the EMCDDA paper and the cited scientific review date from 2008. They provide methodological background, not estimates for 2026.
