But you can't discount that we're all affected differently
For example, although I don't find 5-MeO-DiPT valuable (although I wouldn't call it trash), I find 5-MeO-MiPT to be a very valuable ally. The interesting things about this vast array of synthetic psychedelics we are discovering is that there are limitless possibilities contained within. There are many cases I can think of where one substance is rather worthless to me, while another that is closely related has proven to be valuable and in fact not very similar at all (5-MeO-DiPT vs. 5-MeO-DiPT is but one example).
And I mean, just because we've found a few that are fantastic psychedelics doesn't mean there's no value in finding others that are more specified to particular tasks. Just because LSD or mushrooms can give you the whole psychedelic experience doesn't mean it's not worth looking for others. Many consider LSD, DMT, mushrooms, and mescaline to be all we need, but I say that if we keep discovering new things, we're bound to find more than are at least equally as valuable.
