jwh073 is unique, trippy head high and no anxiety, but does usually require a higher dose. I guess I haven't experienced enough different ones to know one that mimics it's effects considerably. Lately it's been jwh122 for me though, moslty in the head and I don't get any anxiety like I do with 018, well, one of my friends found my 122 blend way too strong and had a hard time with it. But I really find it more forgiving than 018 and if he had smoked my 018 blend I imagine his situation would have been much much worse.
