I believe a liquid solution would be less likely to bother SWIM’s nose.
SWIM has used many nasal sprays before and none of them ever bothered him. It’s the presence of foreign solids that seems to set of SWIM’s negative reaction to snuff.
As far as a salt of bufotenine goes, when SWIM ingests freebase bufotenine orally, the effects are very different, almost like LSA, and it bother’s SWIM stomach (it could be the impurities doing that though). In the stomach freebase bufotenine would convert to bufotenine HCl. I do know that different forms of medications do have different effects. This is a known fact in the pharmaceutical industry. The FDA approves drugs by form. For example, while DMT fumarate is approved for research by the FDA, DMT HCl is not. The same is true for most medications. Some salt forms are toxic, or ineffective, so when a drug is approved by the FDA in a certain salt form, other forms are NOT approved. Each salt form of a drug must be tested and approved separately by the FDA before it can be legally used.
Does DMSO burn your nose? It doesn’t burn SWIM’s mouth.
Calcium hydroxide burns a lot. However, SWIM knows that if you mix calcium hydroxide with freebase bufotenine, and you snort that mix, it is stronger than snorting bufotenine alone. The trip is also better, but the pain is intense. At what pH do the nasal passages get irritated?
According to the Merck Index bufotenine is soluble in both acidic solutions and alkaline solutions, but almost insoluble in pure water. Making an alkaline liquid nasal spray with bufotenine in it should be easy. You’d probably want to use a highly water soluble base like sodium carbonate rather than calcium hydroxide wouldn’t you?
