OREGON: They warned us this would happen. The states where recreational marijuana use is legal are also the states where marijuana is least expensive. The price of an ounce of weed ranges so widely from state to state that someone who smokes an ounce a month can move from Pittsburgh to Portland, Ore., and save enough money for a year’s worth of premium cable, the perfect companion for your habit.
The cost of buying an ounce of high quality cannabis in Washington, Oregon, Colorado and Alaska all cost less than $300 per ounce, less than the nationwide average of $324, according to PriceOfWeed.com, a site where users can anonymously submit the cost of weed in their area purchased either from the black market or legally through a dispensary.
Despite a strong marijuana culture, Colorado is surprisingly not the state with the lowest marijuana prices. At $204 for an ounce of high quality cannabis, Oregon is the state with the cheapest weed – almost half the cost of an ounce of marijuana in North Dakota, where prices are the highest in the country at $387 an ounce.
