None of those links give actual references for the percents (unless I missed it).

As an anecdote, in the late 90s and early 00s, the higher potency stuff was quite prevalent in my circles. The low potency dirt weed was was basically worthless and we would only get it if we were desperate, but it was readily available.

You have to follow the links for a couple of hops.

The key article reference is "Sevigny, E. L. (January 01, 2013). “Is today’s marijuana more potent simply because it’s fresher?”. Drug Testing and Analysis, 5, 1, 62-7."

Well good for you, but some people couldn't get the fancy stuff and didn't mind and actually liked the "dirt weed" and are sad it can no longer be gotten for love or money. You can't even grow your own either because in many of the legal states, it's still illegal to grow but legal to buy from a large cannabis corporation. What a boring dystopia and not at all what the punky hippy "LEGALIZE IT" types of yore can possibly have had in mind!

Yeah, as a Canadian who grew up in this time, it's comical to hear people talk about 5% THC levels in weed. The only time I've experienced something like that was down in Arcata when someone gave me some Mexican brick weed.
