Yes, if you hear people describe a breakthrough on 5-MeO-DMT, then the most plausible explanation for the underwhelming effects mentioned by McKenna is that he simply didn't had a breakthrough experience with the stuff.

I think that if someone where to describe the DMT experience as boring, most people here would probably immediately conclude that this person simply failed to fully breakthrough.

I have not tried 5-MeO-DMT myself yet, but i like the idea that there is something out there that is bigger than anything that i've experienced so far.

And i also like the idea that in a sense the psychedelic scene is evolving. That maybe the world just wasn't ready yet, for 5-MeO-DMT, and that DMT was just one step in a sort of evolutionary proces.

LSD, shrooms, ayahuasca and DMT all offer a very 'sophisticated' kind of experience. And i must say that to me, that is part of their charm. I think it is one of the reasons why these substances do so well in the industrialised world.

But substances like ibogaïne and salvia have shown me that there is so much more, beyond that. That this 'sophisticated part' of ourselves is only the tip of the Iceberg, realy. Especially a substance like ibogaïne totally lacks any sophistication, but it goes a lot deeper than any of the classic hallucinogens, in terms of what i would call 'raw experience'.

There's Always a rabbithole somewhere, that goes deeper than the ones we already know. Or at least, that's what i hope and also believe.
