If you put the DMT on top of your weed, you destroyed it with the flame. You can sandwich DMT in between bud and then just lightly ignite the weed in a corner and keep it cherried. Some people like to use meth pipes to just vaporize it at lower temps. I like gravity bongs best though.
DMT when smoked correctly is the most insane, outrageous, paradigm-smashing thing in this entire reality. Hands down.
