Not DMT I don't think, two reasons - 1) too expensive and rare, wouldn't be practical to lace with it - 2) I've dont DMT before, its out of this world, so unreal, this definitely aint it.

Basically what happens on this stuff is full on 3d hallucinations, loss of vision, loss of hearing, ego-loss, my friend did some and went crazy for like 2 days.. it definitely isn't weed..

Not sure on formaldehyde, don't know enough about it.
