Using DMT fumarate as snuff is very wasteful. No one claimed it wasn’t.

The fumarate is good for 4 things:

1) Long term storage of DMT. Freebase DMT easily degrades, while DMT fumarate is said to be extremely stable. Fumarates are some of the most stable salts around.

2) Oral use with an MAOI. It absorbs better and faster than freebase DMT giving more bang for your buck in pharmahuasca. It can be easily stored for a long time in capsules without refrigeration. It’s perfect for oral use. Freebase DMT in capsules will not last very long unless refrigerated.

3) Insufflation for those who can’t stand the burn of snorted freebase DMT. It is MUCH WORSE than the burn from DMT fumarate. DMT is rather weak by this route unless snorted with an MAOI. This is a wasteful way to use DMT, but some people prefer it.

4) For injection. DMT fumarate is the only form approved by the FDA for injection.

The main reason SWIM is interested in DMT fumarate is because it's a salt and salts are more stable than freebase compounds. If you have a ton of DMT sitting around, it’s best to convert it to the fumarate and store it that way. Then freebase a small batch when you want to use it (unless you use it orally). Fumaric acid should protect the molecule very well. Other acids will also, but they all pretty much form a sticky goo that is hard to deal with. SWIM prefers a powder he can easily handle and it seems only the fumarate and the freebase are powders, while all the others are goo.
