Back during sr1, like almost a year ago i got 10 grams white dmt, it was super smooth to smoke and nice but i havent smoked it much since and ive kept it in a vaccuum sealed mason jar in the closet since then and i go back to it and not only has it turned orangey but its also really harsh and not all that powerful. What happened i thought the vaccuum would prevent oxidation, how are you supposed to preserve this stuff??
I think you can do something with Zinc Oxide that will convert it from DMT Oxide back to regular DMT. Check dmt-nexus.
