Failed Testing, Remediation, and Retesting Guidance (Oregon)

Licensees have the option of remediating and retesting failed product batches.

If a retest for pesticides, solvents, or microbiological contaminants fails the product batch is not eligible for additional retesting and must be destroyed.
Failed AnalysisProduct TypeAction needed for retest
PesticidesFlower, Extract/ConcentrateInstruct initial lab to send portion of sample tested to 2 other labs for retest, inform labs of retest

Or, Have 2 other labs resample and retest new samples, inform labs of retest

Research and Development testing (R&D) can be used to assist with product development or to gather information regarding your production or processing procedures.

R&D test results are not reported to state regulators, unless testing pesticides, in which the state requires submission of test results.

R&D Test Analysis

  • Moisture Content
  • Mold
  • Pesticides (not available for useable flower)
  • Potency
  • Residual Solvents
  • Terpenes
  • Water Activity

Step 1 R&D Test Process and Checklist

  • Name
  • Business name, if applicable
  • Address
  • Phone number
  • License number, if applicable
