The term "marijuana" is 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 term "marijuana" is replaced by the term "cannabis" throughout the Revised Code of Washington (RCW).  The Liquor and Cannabis Board must use expedited rulemaking to replace the term "marijuana" with the term "cannabis" throughout Title 314 of the Washington Administrative Code.  It is specified that the term "marijuana" as used under federal law generally refers to the term "cannabis" used throughout the RCW.

The following types of technical corrections are made in the RCW:  (1) updating internal cross references where prior enacted legislation created inconsistencies with section numbering; (2) correcting scriveners' errors; (3) correcting outdated references to the Washington State Board of Pharmacy to instead reference the Pharmacy Quality Assurance Commission; and (4) removing provisions from the Washington State Medical Use of Cannabis Act that became ineffective on July 1, 2016.
