Thanks for that, this was the kind of thing i was hoping to find. It is indeed a different substance but i would imagine freebase cocaine and dmt vapours to have a similar effect on the lung tissue.

There's no way to know if the lower doses and less frequency of DMT use minimises the risk, or just delays the onset of symptoms.

it seems (to me at least) dmt vapour is likely a lot harder on us than our bodies let on.
