If you did that then there would be a bi-product from the reaction, sodium acetate. It is a non-toxic substance not sure about smoking it, SWIM has smoked harmalas with the same contamination once either way likely the lye in the product would be minimal and thus the sodium acetate bi-product too.
You'd have to choose whether you feel safe smoking trace amounts of sodium acetate of trace amount of lye...
If you do that then make sure to evaporate the vinegar at 70-100C (not hotter, else it will vaporize) until it no longer smells of vinegar, it's a new tek that just uses heat to freebase the DMT-acetate.
SWIM's never done this with DMT and lye, but he has with harmalas and sodium carbonate. SWIM hasn't used lye in a WHILE so he couldn't test it if he tried
