This surface drug test will detect and identify drug residue. The device includes two analysis papers and a liquid ampule which is capable of detecting over twenty different drugs. By rubbing the enclosed analysis paper over the suspect area or substance and dripping a small amount of liquid on to it the paper will change color indicating an identified drug.

Examples of where Surface drug tests can be used:

  • Parents: Testing a cell phone, computer, clothing, bags;  or if you suspect they are using in their car. You can test a steering wheel, seats around the stereo and glove box.  These are things you can do without their knowledge.
  • 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.

How to use the surface drug test for Narcotics:

  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 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.
