California and Washington were long major suppliers in the top 5 producing states, with California first and Washington fifth. The data for that was 2006-2008 era, when I studied this more closely, however, I find it unlikely either of those two has significantly slipped. In addition to the raw volume that they produce, they also serve as conduits for illegal drugs moved across the border (from Mexico and Canada). Oregon also produced, but the volumes were somewhat lower. I have a conjecture that the weed prices in those states are artificially high, because the average person in those states is buying a premium product which there simply isn't enough supply/demand for in states with a) a less direct line to the source, and first selection of choice portions and b) a culture where the dominant cash crop in the state is marijuana -- usually by a non-trivial amount -- making the whole culture of marijuana endemic to the state. Of interesting note is that in 2006-2008, Washington (while fifth overall) was the state which produced the most hydroponically grown marijuana, which fetches a considerably higher price than much of the outdoor crop. Oregon, then, is the first state that represents "the rest of the country" once you step away from weird effects right at the source, and seems to sit in a clear trough around California and Washington. (Such patterns existed back in 2006-2008, and also happened around Kentucky, which is another major producer state.) tl;dr: Seattle people are pot snobs as well as coffee snobs, and the WA price of pot is high for the same reason the average cup of coffee in Seattle is high -- $4 lattes instead of $1 gas station.
