The term "marijuana" is currently used throughout the Revised Code of Washington in areas including adult-use cannabis laws, laws addressing the medical use of cannabis, and laws addressing topics like agriculture, crimes, colleges and universities, public records, compacts with federally recognized Indian tribes, motor vehicles, health care, and taxes. 

The term "Marijuana" is defined in the Uniform Controlled Substances Act as all parts of the plant Cannabis, whether growing or not, with a tetrahydrocannabinol (THC) concentration greater than 0.3 percent on a dry weight basis; the seeds thereof; the resin extracted from any part of the plant; and every compound, manufacture, salt, derivative, mixture, or preparation of the plant, its seeds or resin.  However, the term expressly does not include the following:  (1) the mature stalks of the plant, fiber produced from the stalks, oil or cake made from the seeds of the plant, any other compound, manufacture, salt, derivative, mixture, or preparation of the mature stalks (except the resin extracted therefrom), fiber, oil, or cake, or the sterilized seed of the plant which is incapable of germination; or (2) hemp, industrial hemp, or seeds used for licensed hemp production.

The second substitute bill amends the current versions of several sections of the Revised Code of Washington that include the term "marijuana" and were amended during the 2021 legislative session by unrelated legislation enacted into law.  The provisions of the original substitute bill are the same including the following:  (1) the legislative intent; (2) the provisions replacing the term "marijuana" with the term "cannabis" throughout the Revised Code of Washington; (3) the provision requiring expedited rulemaking by the Liquor and Cannabis Board to change terminology in agency rules; (4) the provision providing that the term "marijuana" as used under federal law generally refers to the term "cannabis" used throughout the Revised Code of Washington; and (5) the other technical changes.
