Heroin Test Kit - Box of 25

The heroin test kit uses a treated cotton swab to test for heroin residue on any surface without the presence of a visible powder or crystal.
Test any surface suspected to have come in contact with the drug, including spoons, needles, baggies and hands. The test is simple and intuitive — and contains no acids, carcinogens or toxic liquids — eliminating any potential risk to the user during testing.
Samples may appear white, brown or black in color and consist of a fine to coarse powder, a hard rock or a sticky residue or in pastes, liquids, oils and vaping juices.
