please see above , chi s post in response to this claim ..Thai sticks originate from the Hill tribes and those same hill tribes are found in Thailand Laos and Burma most with in what we call the Golden Triangle.
The CIA operated there all through the war, and I would bet still do.
as i mentioned before , hmong are not thai people anyhow ,they are from china, and they are not into commercial production of cannabis , they are on tentative ground being in thailand anyhow , doubt they would start dealing drugs and put their existence there to risk further,
they are subsistance farmers , and they usually run stalls at the markets ,
some of these things are known by folks who travel often to these areas and have first hand experience with how things work etc ,
google cannot replace first hand experiences , its fallible, and really cant be relied on to be truthful or accurate all the time , only sometimes ...
