In 2012, Washington State voters passed I-502, legalizing cannabis for adult use.
The LCB is the state’s regulatory agency overseeing the production, processing, and sales of adult-use cannabis.
These web pages address Washington’s legal cannabis market. The topics where LCB is not the primary authority, like medical cannabis or health, will direct you to reliable sources of evidence-based information.
