@amph: That seems like an overly general question, I think that Australia and NZ have very strict laws and tight borders which would increase incidence of NBOMe compounds and other novel psychedelic analogues - though as long as those aren't scheduled as well. That said, it is always possible to have fake acid and I don't believe it works to guess about where it might be circulating a lot. I'd rather see some random reagent testing around the world to support making claims about such trends.
Also whether someone would confuse "some of the best acid" with NBOMe compounds would depend on how well the NBOMe's are tolerated. Yes, they can very well be just as powerful as LSD or more, it is hard to compare though because of dosage differences. But on the other hand not everyone agrees about how good of a psychedelics these NBOMe compounds are.
Talking about 100 or 180 ug doses says very little to me unless independent + free lab analysis is available like in my country... which shows that actual microgrammage is often a lot lower than the hyperbolic advertisement and wishful thinking. Most of the time ug dosage descriptions of acid batches are like a currency of subjective potency. E.g. someone will tell you that a batch feels like as if the dose is 100 ug, or you might have that feeling yourself. Problem is, that might vary between people and you always need empirically confirmed results to start off with as a reference point. Trust me... 99% of the time, that is not what's going on.
Unlike amphetafiend, personally I don't really salute getting hospitalized from combining meth with an uncertain dose of acid, but I am glad that you're alright. I've been experimental, doing combo's and pushing doses, etc.. but what deserves to be called heroic or epic instead actually IMO is: supporting fellow trippers who are going through a very rough time when it turns out there are very unfortunate set & setting issues and shit takes a turn for the worse. (for example)
