Even if there are no signs of a drug, it is still possible to detect its presence.

  • Note: pure Heroin can mixed with many different cutting agents and may result in color variation.
  • Any positive color reactions may take 5 – 10 seconds to develop fully, depending on the quantity and the purity of the substance being tested.
  • Refer the the Color Identification chart, which can be downloaded by clicking the Red Button, below. Every reaction has a corresponding letter and number. You can also compare the reaction with this chart.
