Oregon taxes cannabis less and opens earlier, but Washington stores stay open later — and you cannot legally carry cannabis across the Columbia River in either direction. Portland adds a 20% tax at the register, against Washington’s 37% excise tax plus sales tax. Oregon stores sell from 7 a.m. to 10 p.m. and allow 2 ounces of flower; Washington stores sell from 8 a.m. to midnight with a 1-ounce limit.
Vancouver and Portland face each other across the Columbia River, and many people live in one state and work in the other. Both states allow adult-use cannabis for anyone 21 or older, but taking it over the I-5 or I-205 bridges is crossing a state line, which is illegal under federal law. The simple rule: buy in the state where you will use it.

Is Weed Cheaper in Portland?
On taxes, yes: Portland’s combined 20% is well below Washington’s 37% excise tax plus sales tax. Shelf prices vary by store and deal, though, and Washington stores often build the excise tax into the posted price. Either way, buying in Oregon to use in Washington means carrying cannabis across a state line.
Medical Cards Don't Cross the River
A Washington recognition card only works at Washington’s medically endorsed stores, and an Oregon OMMP card only in Oregon. See medical marijuana in Vancouver.
