Marijuana Information

In November 2012, Washington state voters approved Initiative 502 (I-502), legalizing possession of small amounts of marijuana. I-502 also directed the Washington State Liquor Control Board (WSLCB) to develop a process for regulating the production, processing, selling and delivery of recreational marijuana. We worked with the Washington State Liquor Control Board (WSLCB) to ensure compliance with I-502.
