when you began, DMT existed as some sort of organic salt in the bark, like citrate, so just do another AB. ideally use sodium carbonate this time though, its a gentler base and should help avoid polymerization issues or others. plus doesnt matter too much if you overshoot a lot. the mol weight of dmt freebase is 188g, the salt is that + mol weight of citric acid added on, but citrate can have 1 or 2 citric ions so its hard to say. just aim for a modest overshoot of carbonate which should be around 100g/mol but its 2 sodiums in 1 so, treat it like its 50g/mol. 50g of carbonate will liberate 188g of freebase.
look up "FASA to freebase" or "fumarate to freebase"
citrate or any salt really, will work the same as how they convert fumarate back to freebase, its in the wiki right at the end, just pay attention to how they say you know if you added enough carbonate. if you add your carbonate (not hydroxide tho, needs to be carbonate) slowly to some conc salt solution, and/or shake, its possible to get crystals to form in the water and then you just filter them off and rinse in some clean water. if it doesnt form crystals, you then heat the milky solution you got and it will form a blob of DMT wax. if it forms an oil instead. youll need to use limonene or another NPS to extract it. the blob on the other hand will float and eventually join together into 1 piece.
One last thing, you may be able to do a double-displacement with something like potassium benzoate, or calcium benzoate, to convert your citrate to the benzoate, which can be smoked. But this will probably require you to be able to test the pH to make sure you only have either the monocitrate or dicitrate, or tri citrate, since citrates other than mono may not displace quite right. that would 1-step yield a smokeable salt. ascorbate salts also work (vitamin C neutralized with calcium or potassium), depending on the solubility. like, im not saying it will, just that if you find the right solvent (water, ethanol, methanol, IPA, acetone, etc) that satisfies the requirements for double displacement to occur, then you will get a precipitate forming, either the undesired citrate, or the DMT benzoate.
im pretty sure that calcium benzoate is medium soluble in water while calcium citrate is like 1g/L so it should work based on that. Idk about potassium benzoate tho, it may be an option in some sort of alcohol, but stick with calcium.
Attached is a video of saturated sodium carbonate being dripped into DMT fumarate solution in water, resulting in a precipitate of freebase. citrate will behave the same.
