Maybe I can clear something up that nobody seems to get:
All those Isan landraces were Lao, even back in the 60s.
There is no passport, and ganja and seeds have been crossing the Mekong to and fro for centuries.
The Mekong was the highway then and even now it still is. (There were no decent roads in Isan until Thaksin came along!) It's Lao on both sides!
A big reason the classic ganja of the late 60s and early 70s was grown where it was in Northern Isan was because it was going to Vientiane.
Back then, Vientiane was the big urban centre of that region (Muang Lao).
Places like Udon were tinpot towns by comparison.
Laos wasn't taken over by the commies until 1975.
(That's when Udon became what it is today.)
Before 75, Vientiane was all about fun, sin, whatever - ganja, opium, bar girls etc.
The bar girls in Vientiane were trafficked FROM Isan TO Vientiane.
That was the direction of flow with northern Isan ganja too until Westerners came along.
That's why there were a lot of fields from Si Chiang Mai westwards - a short hop across the river to Vientiane. Also because there were communist guerillas there, so that became a lawless zone where corrupt Thai army etc. could arrange grows.
Also, this thing about throwing buds against the wall until they stick. Anyone believe that?
You could push them against a wall - but throw them?
