I’m a retailer/cultivator/manufacturer thinking about buying product that you tested for pesticides – how can I check to be sure that the product is clean?

Ask them for their Certificate of Analysis (CoA). If you plan to concentrate the material. If they don’t have a CoA, we’d be happy to test the material for you: ask your vendor for a sample.

Before interpreting pesticide test results, you may want to read what the leading authorities have said about pesticide residues in cannabis and otherwise:

• Washington Cannabis Pesticide Action Limits
• WSDA’s Criteria for Pesticide Use in Marijuana Production
• Oregon Health Authority’s Technical Report
• EPA’s “Setting Tolerances for Pesticide Residues in Foods”
