Well so far the best way I have found to smoke DMT is by using partially smoked mj underneath the DMT. The DMT will fall right through a screen once it warms up, and although a friend gave me an oiler pipe, I do not really like using it. If your DMT is not white, then you really need to change out the pot every 2-5 times you fill up the bowl cause otherwise you burn the oils/fats and you will hate yourself for it.
When DMT was working well for me, I noticed I smoked a lot less pot. I don't really see anything wrong with packing a bowl whenever I feel like it, normally I smoke quite a bit of pot. But when I was using DMT, sometimes I would go 2-3 days and just not really feel like smoking pot (or DMT) at all. I was blown away because although I know I can go without weed when I don't have it, I never had it around and didn't smoke it before.
Anyway, you may have read my other post about saying DMT is not effecting me anymore so I am still taking at least a 2 week break from it, and I will test the effects of DMT again then. I agree I didn't want to be really high when doing DMT, but I felt like smoking a bowl was sort of required in order to properly pack the pipe I smoke DMT out of.
