Eager customers bought pot at 8 am (10pm Thailand time) at Bellingham's Top Shelf Cannabis, one of two stores in the city north of Seattle that started selling marijuana as soon as was allowed under state regulations.
Washington became the second state in the U.S. to allow the sale of recreational pot. Colorado began sales Jan. 1.
Washington issued its first 24 retail licenses Monday, though not all businesses planned to start selling weed on Tuesday.
State law allows the sale of up to an ounce (28 grams) of dried marijuana, 16 ounces (453 grams) of pot-infused solids, 72 ounces (2,040 grams) of pot-infused liquids or 7 grams of concentrated marijuana, like hashish, to adults over 21.
