Hello NothinTheory,
Welcome to the Nexus,

.
How far did you get by vaping DMT? Visuals? Entity contact? An encounter with the numinous?
Honestly, the best way to get your question answered is to make yourself into a Citizen Scientist with your consciousness as the research subject.
The first step is to see the Wiki link above, start to read and research, gather materials, get questions answered and do your own DMT extraction to get those glorious crystals of which you express interest, . . . .
Next up get a mg scale and keep it fresh batteried, on a solid, flat surface, and frequently calibrated.
Next figure out how you will vape these crystals that you have extracted. There are may ways/systems, some super cheap and easy and some rather spendy and complex. DMT is seriously worth taking the time to research and do right.
When the time is right, open a journal entry and at a minimum, record the dose, how you got it in you and some subjective effects. The idea here is to start LOW then work your way up (titrate up) slowly until you find a personal sweet spot.
The DMT seas run very deep. But there is much to see and learn in the shallows and tidepools. I honestly believe it is all good.
And it is good that you are here and have questions.
