  • Automobiles: This product can be used to detect drug residue in cars, on steering wheels, dashboards, seats, and more without anyone ever knowing.
  • Rental Properties: Landlords, did you know that you can test apartments and houses for drugs from users and meth houses? You can use the enclosed wipe on doorknobs, air vents, and most surfaces for signs of methamphetamine, cocaine, and more.
  • Schools: Principles, if you suspect drug activity, you can closely monitor student lockers, computer keyboards, cell phones, furnishings, and backpacks. If you think students are using or dealing drugs, use a test where they congregate. Check light switches, books, and other surfaces to see if drugs are being used there.
  • The Workplace: Employers, if you are worried or suspicious of your employees, test their work area. You can check their desk, phone, and keyboard to see if they have been in contact with illegal substances. It’s simple, and no one will know, and no suspicion raised.

  2. Peel back the analysis paper from its silicon backing. Hold it at the edge or corner and wipe a suspect surface.
  3. Hold the pen or ampule and bend in the middle until you hear a crack; this breaks the ampule internally and allows the two liquids to merge.
  4. Hold the ampule with the tip pointing away from you and shake vigorously.
  5. Remove the tip and place one drop of the formulated liquid onto the pad.
  6. Depending on the drug detected, the pad would change color.
  7. The reaction between the liquid, pad, and substance detected produces a unique color.
  8. Compare the color with the chart on the instructions identifying what substance was detected.
