EFFECT:   Amends the new definition of "postharvest test" to also include a test of delta-9 tetrahydrocannabinol (THC) levels of hemp after being harvested based on other approved testing methods (and not only to include a test of THC levels of hemp after being harvested based on ground whole plant samples without heat applied).

Provides that the Washington State Department of Agriculture (WSDA) may regulate the processing of hemp food products that are allowable under federal law to the same extent as the WSDA regulates other food processing under the Food Safety and Security Act and the Washington Food Processing Act. Authorizes the WSDA to adopt rules regulating the processing of hemp for food products, including but not limited to rules establishing standards for creating hemp extracts used for food.

Amends the prohibition on agency rules establishing a distance requirement, limitation, or buffer zone between hemp producers or processors and marijuana producers or processors, so the prohibition applies only to the adoption of such rules without the evaluation of sufficient data showing impacts to either crop as a result of cross-pollination.
