Marijuana processing. Processing that uses chemicals or equipment as regulated by the International Fire Code; this does not include the harvesting, trimming, or packaging of the plant.

Miscella. A mixture, in any proportion, of the extracted oil or fat and the extracting solvent.

Observation. A practice or condition not technically noncompliant with other regulations or requirements, but could lead to noncompliance if left unaddressed.
