Illicit Drug‐Derived Volatile Organic Compounds as Markers for Application in Noncontact Detection Technology

The Chemical Record, Volume 26, Issue 3, March 2026.
This review highlights the characteristic odor markers of illicit drugs, emphasizing volatile markers from both natural and synthetic sources, and explores the shift from canine‐based detection to emerging noncontact sensing technologies. Illicit drug use remains a global concern, requiring effective detection methods to counter evolving concealment ...
