I honestly think the pure skunk was an afghani pheno. It was prevalent but not a "strain", and not a dominant terp - it was one that coule be bred out. And it was thanks to Reagan and his cunt wife. When the DEA was swinging from helicopters and dropping into the woods on tips, the smell was a dead givaway. But it was still outside, so it "could" be an actual skunk.
Indoor growing killed the skunk. Loudness was a trip to the pokey waiting to happen and indoor growers either didn't use it, or bred it to get rid of the stinky.
Both happened in the same few years.
Nancy Reagan and "The Closet Cultivator" killed the skunk
