The Washington State Liquor and Cannabis Board (LCB) licenses and regulates cannabis producers, processors, retailers, researchers, and transporters pursuant to Initiative 502 (2012) (I-502) and laws enacted by the Legislature over the last decade.  In creating the legal structure for the adult-use cannabis market in Washington, I-502 established an intrastate cannabis program where all activities related to cannabis production, processing, distribution, and sales occur within Washington's borders by Washington licensed businesses.  Other states in which voters or legislatures have since legalized adult-use cannabis and established commercial markets also structured their programs as intrastate programs.
 
In recent years, Congress has considered several bills to change the status of cannabis at the federal level, including the Marijuana Opportunity Reinvestment and Expungement Act, the Cannabis Administration and Opportunity Act, and the Secure and Fair Enforcement Banking Act.  Legislation to legalize cannabis under federal law has passed one chamber of Congress at different times but has not passed the other chamber.
 
Oregon enacted an interstate cannabis law in 2019 (Senate Bill 582), and California enacted an interstate cannabis law in 2022 (Senate Bill 1326), both of which have contingent effective dates based on federal law or policy changes.  The laws would authorize the governors of Oregon and California to enter into interstate cannabis agreements with other states regarding cross-jurisdictional cannabis commerce and coordination. 

Subject to a contingent effective date, the Governor is authorized to enter into an agreement with another state or states for the purposes of:  (1) cross-jurisdictional coordination and enforcement of cannabis-related businesses authorized to conduct business in Washington, the other state, or both; and (2) cross-jurisdictional delivery of cannabis between Washington and the other state. 
 
An agreement must ensure that enforceable public health and safety standards are met, and include a system to regulate and track the interstate delivery of cannabis.  Any cannabis delivered into Washington, prior to sale to a consumer, must be tested in accordance with rules adopted by the Washington State Department of Health and the Washington State Liquor and Cannabis Board (LCB).  The cannabis must also be packaged and labeled in accordance with Washington law and the LCB's rules.  An agreement must ensure that applicable taxes on the sale, delivery, and receipt of cannabis are collected.
 
In accordance with an agreement entered by the Governor, a cannabis producer, processor, researcher, or retailer licensed in Washington by the LCB may deliver cannabis to a person located in and authorized to receive cannabis by the other state, and may also receive cannabis from a person located in and authorized to export cannabis by the other state.
 
If either of the two conditions arise causing the bill to take effect, then the LCB must provide written notice of the effective date of the bill to affected parties, the Chief Clerk of the House of Representatives, the Secretary of the Senate, the Office of the Code Reviser, and others deemed appropriate by the LCB.  The LCB must also provide written notice of statutory changes necessary to authorize the sale, delivery, and receipt of cannabis in accordance with an interstate cannabis agreement to the Governor and the appropriate committees of the Legislature.  Last, the LCB must adopt rules as necessary to authorize the sale, delivery, and receipt of cannabis in accordance with an interstate cannabis agreement.
