are those prices for shake? How horrible can weed be for $20 an Oz. If it's actual buds.
The $20 ounces are going to be the low end leafy buds. I've seen and smoked some of the $60 ounces and it's probably better than half the burnt to a crisp and harvested early stuff many on the forums post pictures of after spending $1000 on grow lights and other equipment to end up with a few ounces from a couple autos.
You also have to realize that the vast majority of people buying at the dispensaries are not the pot snobs you see on the forums either. They just want to get high and don't care if some pot snob on a forum calls it mids. Not everyone smokes daily and if they can buy a bag for $60 that gets them high and will last them months then they're happy.
You read posts from people slamming on dispensary weed and then you look at their grows and some of the stuff they harvest isn't nearly as good as what you can get at a dispensary. Oregon prices are low because there's still well over a half million pounds of surplus that's sitting around. Growers that are giving up because they can't make a profit are just dumping their stuff for whatever they can get for it and moving on.
