In Washington the industry is just emerging (at least above board). Since retail outlets will be fairly constrained by zoning regulations and the numbers of permits issued, not to mention the numbers of permits to grow, my sense is that there won't be a big enough market for big tobacco to justify getting involved. At least not at the outset. I wouldn't be surprised if they are watching it closely, though. A neighbor of mine quit his job at a tech startup to start a pot farm in eastern Washington. He has a permit and everything lined up. It will be interesting to see how the market shapes up. Finding places to set up retailers seems to be a challenge. The list of places you can't sell pot (within X feet of schools, community centers, etc.) is long enough to make it tricky to set up a store.
