So then why are we seeing the lowest prices on marijuana for decades (excluding Schwag of course, which is becoming nearly endangered in legal medical marijuana U.S. states)? It turns out the answer amounts to nothing more than simple economics, supply and demand really with the former outweighing the latter.
What is behind the expanding medical marijuana industry causing marijuana prices to fall then, is the fact that the supply of marijuana is beginning to catch up with the outstanding demand. As an economist might put it, it would appear that the price of marijuana in the United States is approaching an equilibrium market price.
Only time will tell where the marijuana trade's semi-emergence from the black market into a semi-regulated open market will take prices of cannabis on the streets and in legal medical marijuana dispensaries.
