I had recently upgraded my lab with a Soxhlet extractor. These things are GREAT! I decided to try extracting bufotenine from Anadenanthera colubrina using my Soxhlet extractor. After reading about Jonathan Ottยs freebase bufotenine experiences, I was dying to try it for myself. So I did an extraction.

Summary
Bufotenin is a naturally occurring tryptamine found in Anadenanthera (Yopo/Cebil) seeds and in the parotoid glands of certain Bufo and Incilius toads. The Colorado River toad (Incilius alvarius) contains primarily 5-MeO-DMT, not bufotenin, and 'toad-licking' is extremely dangerous due to cardiotoxic bufadienolides in the venom. Pure bufotenin freebase vaporizes at approximately 160ยฐC; use low-temperature glass pipes or e-mesh devices to minimize harshness.
Perspectives
“Within a minute (from the start of the injection) I had a tight feeling in my chest and my face felt as if it had been jabbed by nettles and this lasted for about 6 minutes. I had fleeting nausea.”

Rapid acute tolerance is typical of short-acting tryptamines; sensitivity partially returns within hours but cross-tolerance to other psychedelics can persist into the next day. Data quality primarily anecdotal.
Effects
Aggregated from 4 single-substance Erowid experience reports
Each bar shows the share of analyzed reports whose text mentions that effect — a mention is not always a first-hand experience (fear of an effect or something witnessed can count). Mentions saying the effect did not happen are left out; that check reads keywords, so it can miss some. The shaded band on a bar, and the small range after its number, is the 95% interval: where the share could plausibly be with other reports of the same kind. Fewer reports, wider band. Tap or hover any number for details. The second value is the Bluelight extractor's per-effect confidence; a dash means the row is Erowid-derived, which has no confidence measurement.
Too few reports for bars: these effects come from 4 single-substance Erowid reports, and a bar is drawn only from 20 reports or more. With fewer, a percentage cannot tell a common effect from a rare one. Counts are shown instead. Why 20?

I weighed out 15mg of sticky, brown bufotenin resin and placed it in the pipe, playing the flame from a lighter over the tiny bead of material. It vaporised easily and cleanly, the hot smoke pungent with indole and the fishy amine aroma characteristic of bufotenin.
[ Erowid Note: One should not attempt to perform alkaloid extractions without first having an understanding of safe handling procedures for the chemicals and equipment required.] We had read several reports of free base bufotenin being a pleasant experience. We decided to give it a go and see for ourselves.
After having a great experience with sublingual free base bufotenine, the following weekend we played around with smoking free base bufotenine. We smoked doses ranging from 10 mg all the way up to 15 mg. All three of us had positive experiences. The effects are different this way.
