Drug and Contraband Detection
Detection and interdiction of narcotics, weapons, and prohibited materials across every introduction pathway into a secure facility.
The operational problem
Contraband enters secure facilities through a defined set of pathways: employees and contractors, visitors, mail and packages, incoming property, deliveries and vehicles, perimeter throwovers and aerial drops, and returning residents from court, transfer, or work assignment. Each pathway has a different volume, a different legal standard for search, and a different staffing cost.
Synthetic drugs have changed the problem. Paper soaked in synthetic cannabinoids or fentanyl analogues carries no visible signature and defeats visual mail inspection. Detection at trace levels, mail digitization, and controlled property handling have become central rather than supplemental.
Agencies rarely fail because they chose the wrong machine. They fail because a pathway was left unaddressed, or because a detection alert had no defined consequence — no confirmatory test, no chain of custody, no disciplinary or referral procedure attached to the result.

What has to be decided before equipment
Pathway coverage
A program is only as strong as its least-controlled entry point. Staff entrances and mail are frequently the least-addressed.
Detection chemistry
Ion mobility spectrometry, mass spectrometry, and canine detection differ in sensitivity, false-positive behavior, consumable cost, and defensibility.
Alarm resolution
Every positive result needs a defined confirmatory step, evidence handling, and administrative or criminal referral path.
Legal standards for search
Searches of staff, visitors, and residents are governed by different authorities, collective-bargaining provisions, and case law.
Throughput and staffing
Shift change, visitation peaks, and mail volume determine whether a control is sustainable or quietly abandoned.
