PA Groundhogs employs mass spectrometry technology through its affiliation with the Center for Forensic Science, Research & Education (CFSRE), in Horsham, PA, to develop regional profiles of Pennsylvania's illicit drug supply, anticipate overdose clusters, analyze changes in drug purity & composition, and identify new psychoactive substances in an effort to proactively alert Pennsylvanians who use drugs about strong batches, new synthetic analogs, and potentially dangerous contaminants. Other partner organizations include Penn State University's Consortium on Drug Use & Addiction, the Pennsylvania Harm Reduction Network (PAHRN); Narcomedia LLC; KMFK Safety Services; and University of Pennsylvania medical staff, who help facilitate our Clinician Awareness Program.
