There’s non to my knowledge, vaporized DMT is not as wel researched, there is data on DMT concentration in blood (not plasma, but assuming that this is what you mean) in IV as well as IM studies, as in oral preparations, usually as an methabolic marker.
So if you are specifically looking for plasma levels you’re out of luck, blood DMT concentration is well studied and you should have no problem finding many papers on the subject, though usually not as primary outcome.
