OLYMPIA — Washington is looking into allowing patients to have medical marijuana delivered to their door.

The Daily Herald reports the Washington State Liquor and Cannabis Board is conducting a study on how to set up and operate a delivery system.

State lawmakers want a report with recommendations from the agency by Dec. 1.

Lawmakers want the agency to study how to develop and implement a system of delivering medical marijuana to qualified patients from properly licensed retailers.

Among issues the study must consider are how to verify those receiving the product are registered in the state’s medical marijuana authorization database and what payment methods would be allowed.

The Washington State Department of Health says there are 290 retailers in the state with a state-issued endorsement to sell medical marijuana products and about 18,000 active patients.
