INTREPID confirms both liquid veterinary preparations and powdered xylazine are being used to adulterate fentanyl. INTREPID observed chemical markers in xylazine seizures that can assist in determining precursors, synthetic routes, and potentially connecting cases.

Xylazine, reported as an adulterant in an increasing number of illicit drug mixtures, has also been detected in a growing number of overdose deaths. It is commonly encountered in combination with fentanyl but has also been detected in mixtures containing cocaine, heroin, and a variety of other drugs. However, xylazine...

The increasing availability of illicit opioids is the most significant drug threat in Pennsylvania. The Philadelphia Field Division (PFD) monitors this threat closely, periodically reviewing multiple data indicators, in conjunction with investigative information, to continually assess the threat, then share analytical findings with stakeholders in federal, state, and municipal governments.

The Drug Enforcement Administration (DEA) Heroin Signature Program (HSP) analyzes hundreds of wholesale-level heroin samples each year to identify the geographic area—Mexico, South America (SA), Southwest Asia (SWA), or Southeast Asia (SEA)—where the samples were manufactured.

The HSP (Heroin Signature Program) is one essential component of the DEA’s Intelligence Program to identify trends in heroin trafficking and distribution in the United States. The objective of the program is to identify and quantify the chemical components of heroin seized at U.S. ports of entry (POE), all non-POE...
