As we reported last week, Washington Initiative 502 (I-502), a marijuana law reform measure which appeared on the November 2012 general ballot, won the popular vote passing by a margin of approximately 55% to 45%. Now that the initiative has passed, as of December 6, 2012, it will be legal for adults aged 21 years and over to possess up to “one ounce of useable marijuana,” 16 ounces of marijuana-infused product in solid form, 72 ounces of marijuana-infused product in liquid form, or “any combination” of all three.
