Yes you can, you just need to be 21+ and have valid (not expired) ID from any state or country, or even a passport.
You cannot transport back to any other state, however, even legal states. The package will say ", only legal in Washington state. " it's also illegal on trains and buses as they are technically federal property, so if you're looking to just get some while in state it's all legal with Sean's answer..but i would advise against the soul attempting to buy 5 80$ ozs and bringing them to a non legal state to sell. Remember you're in a fed database as soon as you checkout!! I watched border patrol pull one or two dumb guys a week off the train for doing just that. Then you're looking at federal trafficking. Oh, and don't be blazing a blunt on division or down sprague. Lol. Unless you're a passenger. Dui is pretty stiff and if the officer even suspects you can be transported to a hospital, have your blood drawn, and charged. Just some heads up. Best advice for the out of stater is still treat it like it's illegal. Unless you're in a house or ur property u can't smoke in public. Be safe!
