Yellow colour can be a number of things:
- Most of the times, yellow DMT is just DMT. Pure DMT itself has been shown to be
polymorphic , so yellow does not necessarily mean impurities.
But it can also be other things in some cases :
-Oily non-volatile impure solvent remains, if you use a solvent that doesn't evaporate clean (bad to smoke)
-Plant oils/fatty acids or other natural impurities (more likely ok to smoke, and can even make for a more efficient vaporization as it protects spice from the lighter's heat, though might taste a bit harsher)
-DMT N-oxide mixed in any proportions to DMT (ok to smoke, also psychoactive, some people even preffer it to normal dmt, others dont like it so much but it definitely works and is not dangerous)
- NMT (
also psychoactive, though less potent than dmt, about a fourth of the potency).
It can also be a mix of all/any of the above. Usinc clean chemicals to extract will guarantee that at least you don't have any dangerous chemical impurities, and in that case yellow wouldn't be a bad thing in either way.
