I've played around with putting dmt crystals straight into some types of ecigarette device and it works just fine, but I didnt see the benefit because you have to measure each hit or you cant measure the dose. I am working on a way to make pellets of dmt that you can put into the cartomizer using an inert binder, but I havent found a perfectly suitable agent or technique to make little microdots that would vaporize well.
Im using these hashoil cartridges that fit on any 510 battery, they work great for one measured hit at a time. The cartridges are stainless steel, ceramic, and no solders inside. Much easier to load than those with the central tube that is surrounded by polyfill. And no matter what technique any of us use, Im sure its best to get away from the polyfill.

put 15 mg or so into it and you get a great hit, reload and repeat and you can clean them with alcohol if they gum up. Not particulary different than other small vaporizers except that you can use standard ecig batteries with it, which is great.
I did a hit 10 mg tonight and it was very nice.
