Pesticide Screening

Chemical pesticides, even in trace amounts, can be dangerous for human consumption. While certain pesticides are allowed for use in the cultivation of cannabis and hemp, many are not allowed for use because of known or unknown dangers of consumption. Even if you or your cultivator isn’t using chemical pesticides, they can sometimes infiltrate safe crops from neighboring farms using these restricted pesticides. As a result, it’s important to test for any amounts of pesticide in the final product. CannaSafe tests for 66 pesticides in Category 1 and Category 2, according to California State Law. We can test for others upon request. 

What is a Pesticide?

Pesticides are any substance used to deter, repel, or destroy insects or other organisms harmful to cultivated plants or to animals. It’s the chemicals used as pesticides that can endanger humans, and these are what we test for in cannabis and hemp. 

Here are Some of the Pesticides we test for:

An insecticide that is known to be highly toxic. It is used to control mites, nematodes, and aphids through application to the soil. In toxic amounts it can cause cholinesterase inhibition.

HOW DO WE TEST?

In order to test for all 66 types of pesticides, we have to use two different types of analyses based on the properties of the pesticide. 61 pesticides get tested via LC-MS/MS (liquid chromatography tandem mass spectrometry) and the other 5 are tested via GC-MS/MS (gas chromatography tandem mass spectrometry).
