-073 is like a clean, very sativa, nearly pure sativa hybrid style high.
-081 is a tad more psychedelic, a first class modern hybrid high.
-200 and -250 are vaped together, to lengthen the duration and combine the effects. Dosage with these two is much much higher as well, on the order of ten (mg)... really.
-018 is the best bang for your buck however. It's the most novel. I don't think there is cannabis like it. Either that, or it comes close to it and at times being it, or I've had the gall to think even better;
(I still don't have a favorite. But the 200+'s do taste like butter.)
And these are vape highs. These are not like smoking something rolled or packed in a bong or even a bowl... These are vape highs... And to be 'smoked' in an oil pipe.
-What other JWH-XXX are there?
-073 is my favorite. It's pure sativa. I don't know how else to describe it. Its just hallucinogenic like a good sativa can be... Dosing is a snap. You know where you're going, if you know what a milligram of a crystalline powder looks like. And use a torch lighter, -it takes a lot of heat.
Color is not really important, they all have different colors. Ranging from clear, white, to yellow amber and then gold... The only bad one is black.
Cannabis has a much wider palate of possible highs, but these synthetics are only beat by the best weed.
... And people like shepj, brev or endangered, there is still no reason to fear the metabolism of these molecules!?
