NIST is measuring the trace chemical signatures and quantities of trace residues and background levels that contaminate surfaces associated with the concealment of illicit drug materials including fentanyl and its analogs.  Current efforts include: documenting a swiping protocol for sampling packages and the surrounding area for optimized collection of trace illicit drug residues, identifying background contamination present on seized packages and those exposed to the stream of commerce and assess its impact on IMS performance and the ability to identify suspect packages.
