More info

The NarcoCheck® ID-Test® for Cannabis is used for the identification of THC (Tetrahydrocannabinol), the active ingredient in cannabis. It works whatever the form of cannabis, ie on samples of hashish, weed (marijuana) or oil.

Very simple to use, this test is based on a wet chemical reaction.

Introduce into the test a small quantity of the substance to be identified as well as the small catalytic pellet contained in the cap, and the granules contained in the ampoule change color. Then compare the color of the granules with the color chart on the front of the operating instructions.

Before the test, the ampoule is completely transparent.

After the test :

  • If the ampoule turns to REDDISH, the sample tested contains THC. It is therefore cannabis.
  • If the ampoule does not change color or if it takes another color, the sample tested does not contain THC. So it's not cannabis.

The test is provided with a color chart to identify exactly the color showing the presence of cannabis in the sample tested.
