No one ever saw it. No one ever heard about it. For a very simple reason. It never truly happened. Any more than the HT BS. We are talking about very large commerical crops that were being imported into the US. Totally 100% BS.
I have no idea on that one historical fact or myth, but High Times was not the holy bible in terms of accuracy.
They did a Hawaiian story and had all kinds of fancy named buds in the pictures, Puna Buds, Molokai Killer etc. Turns out the guy that they got them from knew they wanted stories/hype and gave some random stuff he had growing in his backyard all kinds of names.
Stuff got sold as whatever the seller thought would bring the highest price. I recall in '74 I saw a baggie of lawn grass and foliage clippings being sold as pot at school.
