The THC Drug Testing Kit solely tests for THC. The colour change will correspond to the information sheet and colour chart included.
The THC test use a chemical reagent absorbed in silica gel, which is held inside a glass ampoule.
When a sample is added to these chemicals inside the ampoule, if and when a reaction occurs a colour change will take place. This colour should be compared to the colour chart included on the instructions within the package, to give an indication as what could be in the sample.
The EZ testing kits are purely a guide to help analyse a substance. It is advised not to touch any substance and extensive laboratory testing of samples is recommended for more detailed results.
