Regarding extraction, have you looked at the huge amount of information on this site? Its a wonderful resource. If everyone had to make a post asking for info that has already been documented we would have a messy forum full of hot air.

I would recommend the BLAB. Then a water and sodium carbonate conversion to freebase. Followed by a recrystallization.
This is what i believe to be the most righteous extraction method of DMT.
That said, as mimosa may not be available anymore... folk may use different plants with different chemical profiles.
Tho this is DMT, all the "tekz" for extracting DMT should work for Acacia. Impurity's may be different, and plant fats and oils may be a factor.
The chemical principles never change. There are various techniques to deal with such variables. Like defatting and recrystallization. The use of FASI also.
Good luck brother. Be careful. Recognize the risks.
