The wipe will turn speckled blue when it identifies trace amounts of residue left on a surface where cocaine has been used. Results are not evidential but they provide a quick indicator so officers can decide if further evidence testing is required.
Please Note:
These cocaine test swabs are designed for quick, on-the-spot screening. They use a special chemical that reacts with cocaine, however, it can also react with some legal substances like lidocaine, procaine, certain prescription drugs, and even acetone, which is found in many cleaning products.
Because of this, the test is not 100% specific to cocaine- it’s meant as a preliminary tool only. Results are not valid for court use, but they can help guide further investigation or testing
