Officers shall identify marijuana, usable marijuana, marijuana concentrates, and marijuana-infused products during on-site inspections of licensed producers, processors, and retailers of marijuana by means of product in the traceability system, and/or by observation based on training and experience. Products that are undetermined to be marijuana, usable marijuana, and marijuana-infused products will be verified by the following:

(1) Officers may take a sample large enough for testing purposes;

(2) Field test kits may be used if available and appropriate for the type of product being verified; and

(3) Those samples not able to be tested with a field test kit may be tested through the Washington state toxicology or crime lab.
