Instant, On-Contact Detection of Synthetic Drugs
Today, the prison mailroom is the critical frontline in the fight to prevent illicit substances, including powerful and deadly synthetic cannabinoids, from entering correctional facilities.
Organised criminal gangs are exploiting the prison mail system by spraying or dissolving powerful synthetic substances, like K2 and Spice, into paper to bypass the manual screening process.
At the same time, illicit items of clothing, fabric, and herbal materials are increasingly being used to distribute these dangerous chemical solutions throughout the facility.
Where other technologies struggle to keep pace with constant chemical mutations, ContraSCAN provides a uniquely uncomplicated, handheld solution that enables mailroom staff to instantly detect the presence of synthetic cannabinoids with minimal training, low investment, and immediate results.

Hazard Detection: Red LEDs indicate the presence of synthetic cannabinoids.
Immediate Instant On-Contact Detection
With minimal training required, the operator need only pass the ContraSCAN device over suspect paper, fabric, or herbal materials, screening large areas in seconds. Red warning LEDs indicate the presence of synthetic cannabinoids – highlighting an immediate risk.
Paper and Card. Intercept synthetic drug-infused mail.
Proven To Identify High-Risk Contraband
Trialled in correctional facilities across North America and Europe, ContraSCAN is actively empowering staff to instantly flag drug-infused mail and intercept dangerous, potentially lethal chemicals through mailroom screening and routine cell searches.
Dried leaf and Herb. Effective screening of smoking products.
Precision Engineered for Accuracy & Durability
Designed specifically for use within a correctional environment, ContraSCAN stands up to the rigours of daily deployment, whether in the mailroom or on the move. Its robust, machined exterior houses high-grade LEDs engineered for a continuous lifetime of over 10,000 hours.
Fabric Screening. Scan complex substrates and materials.
Economical No Database Updates Required
While current detection techniques require either ongoing consumables or regular database updates (to keep pace with rapidly evolving chemical formulations), ContraSCAN requires neither. Thanks to a unique optical detection method, ContraSCAN is always up-to-date and ready to deploy.
LED Interface Instant Hazard Notification
Red LEDs indicate the presence and intensity of synthetic cannabinoids.
Detection is instant and unequivocal, leaving nothing to interpretation.
Safe Operation Putting the Operator First
When used with standard PPE, operator safety is fully assured. ContraSCAN incorporates built-in safety interlocks, a deadman’s trigger, and a positional sensor mechanism that ensures the device only activates when placed securely against a flat surface.
No Calibration Needed Verified Device Performance
Ensure the accuracy of device efficacy using the supplied performance
accessory quickly and easily before use, with no ongoing calibration
required.
