you would have to have in-depth chemistry and legal knowledge to know exactly what is illegal under the US analogues act. but if you can't show that a substance is closely related to something already under schedule I or II, it is legal (or at least not illegal) by default. now that the popular 2C-x's have been explicitly added to schedule I, my guess is that the whole family is on thin ice, if not unambiguously illegal.
