Most Oregon hemp fields passed the preharvest THC test in 2020

As of early December 2020, 93% of Oregon hemp fields (harvest lots) which had undergone a preharvest THC test, had a total THC percentage less than 0.349 and thus passed that test.

One concern from past seasons was the ability for producers to select genetics and make harvest decisions which prevent hemp crops from testing "hot" or having a total THC content greater than 0.349%. These data, provided by Oregon Department of Agriculture, indicate that the vast majority of the harvest lots tested fell below that THC threshold.

Note that some registered hemp production areas (fields) may not have undergone a preharvest test by early December because of crop failure, misinterpretation of testing requirements, or other reasons.

See the Oregon Department of Agriculture's website for more details on hemp testing.
