THC is not water soluble, And the heat use to brew It would more than like destroy all the THC, In theory. It could be Sun Tea which would bypass a high brewing temp which is between 195-205 for regular tea and coffee. I say In theory becuz I hear alot about Weed Tea but have yet to try it my self, It could actually work. But I dought It becuz if weed tea was possible, then water curing would be pointless for cannabis growers,lol all your THC would leach into the water if it was water soluble
