“After 29 years of being a probation officer, substance abuse detection has had little advancement. D4D’s Presumptive Drug Detection Technology (PDDT) improves drug use detection and is long overdue.”
– Thomas G. Pinner, Pinner Counseling

“Using PDDT means police officers no longer have to obtain a sample of the suspected narcotics or risk contaminating the evidence.”
– Rob Ernst, Law Enforcement Consultant

“As a presumptive test for law enforcement, D4D is ideal for not only determining the presence of trace drug residue on a surface, it can also be used to apply for a search warrant or as evidence in court.”
– Ian C. Simmons, Attorney
