The convertion of freebase to a salt is pursued for meir reasons than insufflation alone. A major reason for SWIM is investigating all these funny little properties of dmt that make him experience what pure science feels like. Apart from insufflation however dmt fumarate is supposedly very stable and thus an excellent way of storing dmt (in case one has fairly large quantities). Or, as in the case above and below pursuing one thing may give inspiration for other aspects of dmt work, i.e. extractions)

69ron writes of some really good ideas! I was also thinking of a possibly simpler method:

1) acid extraction of MHRB. Your acid is FUMARIC ACID, so you convert all dmt to fumarate salt

2) boil down the extracts to a very very low volume.

3) add excess of acetone and cause precipitation of fumaric acid and DMT fumarate

4) collect precipitate and freebase it

SWIM would like to test the solubility of dmt fumarate in 90%, 80%, 70% etc acetone (the rest being water and/or fumaric acid solution) to see whether this is a viable strategy.

Or, even even better:

1) extract MHRB with acetone and filter off all pieces. (soxhlet should work miracles here)

2) (optional)evap to a managable volume.

3) add excess fumaric acid.

4) see the beautiful precipitate falling.

5) freebase it

69ron, can your friend or anyone else test whether the fumarate salts of other psychoactive alkaloids (i.e. 5meodmt and jungle spice) show similar acetone insolubility?
