A UK Home Office survey found 25% of women aged 18 to 24 reported drink spiking at bars or clubs in the past year, and forensic labs across multiple countries keep finding patterns in what is being detected. From GHB and Rohypnol appearing in nearly half of tested drinks in some datasets to benzodiazepines and alcohol overpouring showing up repeatedly, the numbers are unsettling and often inconsistent. Read through the full set to see how substances, reporting rates, and victim profiles vary from place to place.

How We Rate Confidence
Models
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Single source
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Directional
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
Verified
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
