That might be the case where you live but I have seen none in anyones garden around here and none in the many plant shops ( lower Petchabun ). People not talking about it , seen nobody smoking it , not caught a whiff of anything . Seems to be a complete lack of interest. Having said that , this is a hard drinkers area so maybe they are happy with their Lao Khao ? Who knows. I was thinking of getting some but not seen anything although wife did see somebody on the back of a saling with a small 1 foot plant.
Not bothered either way.
