No, skunk weed has been around since the 80’s that I know of, though I’m sure it was around prior to my knowledge of it.
It refers to a particularly stinky weed. It reeks. In a very good way.
You know it as soon as you smoke it, because it doesn’t smell like any other weed, and it’s quite potent.
In terms of recent, high THC varieties, the only one I cam across that qualifies as skunk weed was what I referred to as California purple weed. Literally purple. I recall that it is generally Humboldt County outdo, as the brothers say. Just the smell of it alone will knock you out, you don’t ven need to smoke it. You can smell it from a mile away while it is not even being smoked and is in multiple plastics bags or even vacuum sealed.
No, that is the old definition. The article itself cites the current usage: “Almost all cannabis on Britains streets is skunk, which is four times more powerful than types that dominated the market until the early 2000s. It can even trigger hallucinations.”
