Washington Bill Would Set Framework for Interstate Marijuana Commerce

Legislation filed today in the Washington House by Representative Sharon Wylie (D) would lay out how the state’s legal marijuana system would handle interstate commerce if and when federal law changes to allow it. The bill was referred to the Consumer Protection & Business Committee.

The proposal is designed to prepare Washington’s regulated marijuana market for a future where cannabis can legally move across state lines, without authorizing interstate sales ahead of federal action. Under the bill, marijuana brought into Washington from another state or country could only enter the legal market after federal law is amended or the U.S. Department of Justice formally allows or tolerates interstate marijuana transfers.

If those federal conditions are met, any marijuana entering Washington from outside its borders would be required to pass through a Washington-licensed cannabis processor before it could be sold at retail. Those products would also have to meet the same testing and quality standards that already apply to marijuana grown and produced within the state, including testing by independent laboratories accredited by the state Department of Agriculture.

The legislation also updates existing state law to clearly allow licensed processors, once authorized by regulators, to purchase and receive marijuana products from legally operating businesses in other jurisdictions. At the same time, it makes clear that nothing in the bill allows interstate marijuana commerce to begin before federal approval, and it explicitly keeps the state’s ban on selling marijuana to consumers by mail or shipment.

In addition, the bill gives the governor authority to enter into agreements with other states to coordinate enforcement, tracking, testing, labeling, and tax collection for interstate marijuana transfers, but only after federal barriers are lifted. Any such agreements would have to ensure public health and safety standards are met and that applicable taxes are collected.

Supporters say the measure is about readiness, not expansion, ensuring Washington’s market is protected and regulated if interstate marijuana commerce becomes legal at the federal level.
