It's not from pot. That came from communist/leftist politicians in Sacramento.
I don't even know what state you're in, but I'll bet the productivity and economic numbers in CA are higher than your state or any state in the U.S., by a series of magnitudes.
So? My experience with wealth and eccentricity is that the one usually begats the other. California is nuts precisely because it has so much wealth.
The Slave owning South also had a higher per capita income. It didn't make them smarter or better.
