White N-N-DMT :
"White N-N-Dimethyltryptamine (DMT) is pure DMT. It is generally up to 1% of the weight of the bark, though less than 0.5% and up to 2% are not unheard of.
In the past the goal of most extractions was to get these pure white crystals, the bark however has more than just that to extract. There are some toxins that cause nausea when eaten, some inactive chemicals and lots of plant matter. But more interesting and more important are 2 other psychoactive alkaloids with similar effects (which some consider preferable) to White DMT. "
Yellow DMT-N-oxide :
"DMT-N-oxide While previously thought to be the reason for the yellow in "impure" DMT, actually Oxides may or may not be present in the MHRB and thus may or may not be in the end product. It is a fact that White DMT does oxidize into DMT-N-oxide when exposed to ambient air for extended periods of time.
Oxides (by SWIM's tests) are about 1/3 or less potent than white DMT or jungle DMT when smoked but equally potent when used in pharmahuasca. "
Red "Jungle" DMT :
"The "Jungle" alkaloids are a group of alkaloids contained in the bark.
Jungle DMT when smoked or consumed in pharmahuasca produce effects similar in duration and somewhat similar effects to N-N-DMT but noticeably different.
Contrary to what some believe there is nothing "dark" about the effects of Jungle DMT, at least no more than any DMT. The effects are just somewhat different, but more or less like DMT "
