Legislative History
Washington voters legalized recreational cannabis for adults 21+ in 2012 via Initiative 502, permitting possession of up to one ounce, home cultivation (later restricted), and licensed retail sales (which began in 2014). Medical cannabis was legalized earlier in 1998 through Initiative 692, establishing a patient registry that was later merged into the recreational framework.
