To make a cart style vape juice, you would use a pg/vg mix, and dissolve the dmt into it. Check in the wiki for the ratios, as there should be a tek write up in there for making a juice. And this wouldn’t be changa, as it would be missing the harmalas. That would just be a dmt vape juice. Loveall has a write up in there as well on using a salt juice that will hold both the dmt and harmalas in vape form.
And no, dmt can’t be extracted in a similar way to THC. THC is in a trichrome form on the exterior of the plant. Dmt is a compound chemically embedded in the plant, that takes a process to separate and extract.
