Welcome to the Nexus!

I like your desire for any claims made to be backed up, but, IMO, the understanding of the DMT experience is at present not provable by scientific enquiry.But if we were to use 'anecdotal' evidence when contemplating it, this battery of evidence is compelling insofar as it does unbelievable things which only first-hand experience can give an inkling of.

It poses more questions than it answers but this doesnt diminsh the pursuit.

Once more, welcome!
