Probably the most pleasant method of using 5-MeO-DMT is sublingually as a salt. This way the trip is much less jolting. The peak gradually builds and the whole trip lasts longer. I enjoy it much more this way, but not if freebase is used because it BURNS LIKE HELL. Instead 5-MeO-DMT fumarate is used sublingually. 5-MeO-DMT fumarate doesn’t burn. It’s mild and tastes like sour plastic. Just 5 mg under the tongue is enough for pretty good effects. There’s not much visuals and there are a lot of mental effects going on. It’s mentally very active and similar to LSD. There are some unusually sensations felt that are hard to describe. 5-MeO-DMT in some ways is like alcohol, in that you feel a little cloudy.
Mixed freebase 5-MeO-DMT with citric acid and water and took it sublingually and found it works just as well as the freebase. It didn’t burn like the freebase does. It’s likely that any salt form is going to work sublingually.
The natives use a simple water extract with no acids. The extract is formed into pellets that are taken orally. I suspect that they let it sit in their mouth and it is actually absorbed sublingually
