Depends entirely upon what part of the country you're from.
There are more cannabis plants per capita here than anywhere else in the country not named Hawaii. And even then it's close. That being said, Kentucky still sees a LOT of brick weed. Not this time of year though, it's outdoor indica season.
Non-Psychedelic Hard drugs (Coke, Heroin, Speed) are worth a hell of alot (100s of times more) more money, though. Heroin is beginning to get to be a big deal around here, which is unfortunate. They just popped a guy I went to school with with 80 kilos of uncut heroin, worth $130,000+ apiece. That motherfucker still owes me money from the old school days.
