(Salem, OR) -- Oregon's recreational marijuana market is saturated. The state has more retailers and production than most other states where pot is legal. Josh Lehner, an economist with the state of Oregon, says prices are low, which is good news for consumers, but not for retailers. Oregon taxes weed based on the sales price, so lower prices also means less revenue for the state. Over the next two years, tax revenue is expected to be down 36-million dollars which means less money for drug treatment programs.
