Hi there,
That pipe, upright, would be fine for changa.
It might work fine, upright, for freebase DMT.
Don't turn it upside down. Either gravity pulls the DMT down, or you risk drawing the flame into the bowl and burn the DMT.
I'd probably consider other options. Pending price, just get a Glass Vapor Genie. That's the best DMT apparatus, that I have used, for easy and effective vaporization.
Take Care,
ACY
Sometimes it's good for a change. Other times it isn't.
