Does anyone know what the difference between the various colors (foil) of Thai brick weed?  Different strains, place its grown..? Red thread being the most expensive… anyway, any information helps my curiosity. Thanks!

bearing in mind the availability of the Items you mentioned, I doubt if any of them are reliable indicators of strength or quality, best to get to know the person you buy from if possible, otherwise its a bit of a lottery

all basically the same. not much difference at all. 

Yeah, there's no Appellation d'Origine Controlee for dirt weed.

 

It's whatever color wrapping paper was left in the store, and the thread thing is just beyond silly.
