What Does It Mean To Be ORELAP Accredited?

Oregon requires all cannabis testing laboratories to be accredited by ORELAP (Oregon Environmental Laboratory Accreditation Program) to the 2009 TNI Standard.

Being accredited by ORELAP means that a laboratory must show they have both the proper quality systems in place, as well as the technical capabilities to perform the required testing.

At Green Leaf Lab, we only test Cannabis. This allows us to focus all our resources on providing Oregon’s cannabis industry with expertise to deliver superior cannabis testing and quality customer service.







What Are The Recent Changes in Oregon’s Testing Rules?

As of October 1 2016, both medical and recreational marijuana producers and processors in Oregon are required to have their products tested to standards that will help ensure public health and safety.

  • Laboratories are required to test for specific pesticide and residual solvent compounds.
  • Laboratories are required to perform sampling of cannabis products to ensure representative sampling. Representative sampling occurs when samples are taken in multiple locations to ensure that the test results properly represent the whole batch.
  • Laboratories are required to test for water activity in usable cannabis flower. Water activity shows the amount of water available in the flower. The amount of water molecules that are available for hydrating the flower can affect the potential of mold growth.
  • Batch testing is required for usable cannabis flower. A batch was considered 10 lbs.; now 15 lbs.
  • Homogeneity validation is required following specified sampling protocols or via control study certification. Homogeneity is the process in which consistency is proven in products such as extracts, concentrates and infused food items.
