Source-derived summary

2C-B-FLY is a psychedelic and designer drug of the phenethylamine, 2C, and FLY families. It was first described in 1995 by Aaron Monte, Professor of Chemistry at UW-La Crosse.

Use and effects

2C-B-FLY was not included nor mentioned in Alexander Shulgin's 1991 book PiHKAL (Phenethylamines I Have Known and Loved). In his subsequent 2011 book The Shulgin Index, Volume One: Psychedelic Phenethylamines and Related Compounds however, he listed 2C-B-FLY's dose as 2.5 to 10 mg orally. On the other hand, other sources give 2C-B-FLY's typical dose range as 10 to 20 mg orally. The duration of 2C-B-FLY is said to be 6 to 10 hours but up to 20 hours. The effects of 2C-B-FLY have been reported to include euphoria, enhanced interpersonal communication, improved mood, closed- and open-eye visuals such as brightening of colors and visual hallucinations, feelings of insight, stimulation, tactile enhancement, sexual enhancement, and altered time perception. Other reported effects include pupil dilation, muscle twitching, restlessness, tachycardia, and body temperature changes.

Toxicity

The toxicity of 2C-B-FLY in humans is unknown. Two deaths occurred in October 2009, in Denmark and the United States, after ingestion of a substance that was sold as 2C-B-FLY in a small-time RC shop, but in fact consisted of Bromo-DragonFLY contaminated with a small amount of unidentified impurities.

Editorial summary

Begin with the source’s own compact description: “2C-B-FLY” is chemical compound. The dossier treats that line as a proposition to test through 2C-B-FLY, chemical and compound, not as a finished interpretation.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current lead gives the account dated anchors—1995, 1991, 2011, 2009—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, 2C-B-FLY, chemical and compound is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “chemical compound” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Aug 25, 2026. The linked authority identifier is Q4633042. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1995, 1991, 2011 and 2009.

Critical limits

Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
