bongs work, just put a screen below and on top, to help keep direct flame off of it.(ive ever done it from a bong, but ive heard it works fine as long as you dont expose it to direct flame.)
My friend used a light bulb vape. Not the same one he uses for weed, he made a new one just for the DMT.
glass pipe if fine jsut be carful some might get stuck on the sides of the bowl meaning you could have a larger dose then you measured... be careful with multipul smokings in a row
You can actually get a DMT pipe. It's got a 3-tiered bowl. Kind of looks like a meth pipe. Failing that, just use a pipe or a lghtbulb vape.
