Sadly that's par for the course for most place to buy in CO. The quality at shops, to me, has been low for a long time. That's the main thing people complain about in terms of CO Cannabis: low quality abounds. Though, to be fair, the same can be said about WA's recreational shops (generally poor quality), and much of the medical market, as well.
Meh. "Low quality" isn't really accurate. "Low" as compared to what?
I contend that the average potency of commercial weed is much higher than 40-45 years ago or at any time in the past, even if the very best is only marginally stronger than it was way back when.
The whole notion of quality needs to account for other factors, as well- aroma, flavor, smoothness of the smoke, even the often under appreciated qualities of the high itself. Some of the best I've ever smoked wasn't the most potent, but rather had superb smoking qualities & an expansive ebullient effect. Wings for the mind. Emotional helium.
A fair % of modern cannabis doesn't seem to have that but is rather more soporific, not really mind expanding in a way that this old hippie really appreciates. I think maybe that's because it's been bred for analgesic medical purposes rather than recreational.
My perspective is unusual, having only come back to cannabis for a couple of years after 25 years of abstention. Lots of younger tokers don't know how good they have it, to be honest.
