|Summary sheet: 2C-B-FLY|
|Chemical class||Phenethylamine / Benzodihydrodifuran|
|Routes of Administration|
2C-B-FLY is a lesser-known novel psychedelic substance of the phenethylamine and benzodihydrodifuran classes that produces an array of psychedelic and entactogenic effects when administered. Reports have characterized its effects profile as possessing features of 2C-B, mescaline and MDA, with a duration of 6–8 hours (or up to 12 hours in larger doses).
2C-B-FLY is a derivative of the 2C-x family of psychedelic phenethylamines, specifically 2C-B, of which it significantly differs from in terms of its potency, metabolism, and potential toxicity. It was first synthesized by Aaron P. Monte in 1996.
Around 2005, 2C-B-FLY appeared and gained some popularity in the online research chemicals market before largely disappearing in October 2009, when a batch of Bromo-DragonFLY was accidentally mislabeled as 2C-B-FLY (Bromo-DragonFLY is dosed in micrograms, where 2C-B-FLY is dosed in milligrams) led to two deaths as a result of taking overdoses of Bromo-DragonFLY meant to be effective doses for 2C-B-FLY. This event led to its immediate withdrawal until around 2016, when it resurfaced on the market again.
Very little data exists about the pharmacological properties, metabolism, and toxicity of 2C-B-FLY, and it has little history of human usage. It has no documented history of being sold on the streets and is commercially distributed through online research chemical vendors.
Due to its high potency and sensitive dose-response, many reports also indicate that the effects of this substance should not be seen as a simple substitute for 2C-B. It is highly advised to approach this potent, long-lasting, and unpredictable hallucinogenic substance with the proper amount of precaution and harm reduction practices if choosing to use it.

In a 2007 MAPS newsletter interview, Ann Shulgin revealed that 2C-B-FLY as one of her favorite psychedelic substances while also acknowledging the high variability in responses it seemed to display.
|“||I said often, too often, that something called 2CB Fly (sic) was absolutely great for me. To me, it’s the loveliest thing, especially for eroticism. But I found out that it’s not interesting to anybody else. I realized that having said that, I was putting things in motion. The Internet was full of 2CB Fly (sic), and people were asking about it and I thought “uh-oh.” It turned out that it’s a disappointment to most other people.||”|

2C-B-FLY is a substituted molecule of the phenethylamine and dihydrobenzofuran chemical classes. 2C-B-FLY features a phenyl ring bound to an amino (NH2) group through an ethyl chain and contains a bromine atom attached to carbon R4 of the phenyl ring.
It is an atypical psychedelic phenethylamine which is closely analogous to 2C-B; it is the dihydrofuran analog to 2C-B, where it incorporates the methoxy groups bound to R2 and R5 of 2C-B into five-member dihydrofuran rings fused to the central benzene ring.
2C-B-FLY belongs to a group of phenethylamine derivatives referred to as the FLY compounds, named for their insect-like appearance of two “wing-like” tetrahydrofuran rings fused on the opposite sides of the central benzene ring. The incorporation of the two methoxy groups into the 5 member rings fixes them into the optimum position for binding to the receptors they interact with resulting in an increase in potency compared to the compound's non-rigid counterpart 2C-B.
However, the role of these interactions and how they result in the psychedelic experience remains subject to on-going scientific investigation.
In comparison to 2C-B, this compound presents a significantly more pronounced body high/load, stronger visual effects, more complex geometry and more in-depth internal hallucinations which are comparable to mescaline, 2C-E or MDA at higher doses. Lower doses, however, are associated with more entactogenic as opposed to classical psychedelic effects.
Disclaimer: The effects listed below are cited from the Subjective Effect Index (SEI), which relies on assorted anecdotal reports and the personal experiences of PsychonautWiki contributors. As a result, they should be taken with a healthy amount of skepticism. It is worth noting that these effects will not necessarily occur in a consistent or reliable manner, although higher doses (common+) are more likely to induce the full spectrum of reported effects. Likewise, adverse effects become much more likely on higher doses and may include serious injury or death.
The physical effects of 2C-B-FLY are comparable to that of traditional phenethylamines such as 2C-E, mescaline and 2C-T-7 along with more pronounced side effects.
There have been reports gastrointestinal disturbances following the use of this compound which include diarrhea, nausea, moderate to severe stomach bloating and general gassiness at moderate to heavy doses. These effects are comparable to that of 5-MeO-MiPT, 2C-T-7 and other compounds with suspected MAO-altering properties. This suggests that 2C-B-FLY may potentially have such MAO-altering properties of its own, which may make it dangerous to combine with certain substances.
- Stimulation and Sedation - At light dosages, this compound is generally stimulating but in a gentle, non-forceful manner similar to that of 2C-B or mescaline. At higher dosages one may find the amount of stimulation to increase to an uncomfortable level with undertones of sedation or lethargy in a manner similar to that of 2C-C or 2C-T-7.
- Spontaneous physical sensations - The "body high" of 2C-B-FLY can be described as a pleasurable, warm, soft, all-encompassing and mild tingling sensation. This maintains a consistent presence that steadily rises with the onset and hits its limit once the peak has been reached. It is comparable to that of a milder mescaline, 2C-B or 2C-E experience.
- Tactile enhancement
- Temperature regulation suppression - Compared to 2C-B, this effect is far more pronounced and unpredictable in its manifestation. Small increases in the dose may result in large changes in this effect.
- Bodily control enhancement
- Bodily pressures
- Increased blood pressure
- Increased libido
- Headaches - This effect is more commonly reported than 2C-B or other traditional phenethylamines.
- Muscle cramps
- Stomach bloating
- Stomach cramps
- Excessive yawning
- Watery eyes
- Pupil dilation
- Teeth grinding
- Drifting (melting, breathing, morphing and flowing) - In comparison to other psychedelics, this effect can be described as highly detailed, slow and smooth in motion, intricate in appearance and unrealistic/cartoon-like in style. It is very comparable to that of 2C-B or mescaline.
- After images
- Colour shifting
- Depth perception distortions
- Perspective distortions
- Symmetrical texture repetition
The visual geometry that is present throughout this trip can be described as more similar in appearance to that of mescaline, 2C-B and 2C-D than psilocin or ayahuasca. It can be comprehensively described through its style variations as intricate in complexity, abstract in form, synthetic in style, structured in organization, brightly lit and multicoloured in scheme, glossy in shading, flat in edges, large in size, fast in speed, smooth in motion, angular in corners, non-immersive in-depth and consistent in intensity. They have a contradictory combination of a very "natural" but also "neon digital" feel to them and at higher dosages are significantly more likely to result in states of level 8B visual geometry over level 8A.
2C-B-FLY produces a moderate range of hallucinatory states in a fashion that is comparable to mescaline or common doses of 2C-E. This is more consistent and reproducible than that of many other commonly used psychedelics such as 2C-B or LSD. It tends to occur at heavier dosages and integrates seamlessly with the accompanying geometry. These effects generally include:
2C-B-FLY tends to maintain a level of relatively normal and sober thought structure regardless of the subjective visual, physical and cognitive accompanying effects intensity. This leaves the user in control in a manner which would not be possible on many compounds such as 4-AcO-DMT or LSD due to their accompanying confusion and delusions.
- Conceptual thinking
- Creativity enhancement
- Emotion enhancement
- Empathy, affection, and sociability enhancement - This compound presents entactogenic effects on a level which is less intense than that of 2C-B or MDMA but similar in quality to that of mescaline or 2C-E.
- Increased libido
- Increased music appreciation
- Increased sense of humor
- Memory suppression
- Novelty enhancement
- Thought acceleration
- Time distortion
- The effects which occur during the offset of this compound are comparable to that of a mild stimulant or entactogen. The experience generally feels negative and uncomfortable in comparison to the effects which occurred during its peak. This is often referred to as a "comedown" and may occur due to the physically fatiguing aspects of this substance. Its effects commonly include:
There are currently no anecdotal reports which describe the effects of this compound within our experience index. Additional experience reports can be found here:
Toxicity and harm potential
This toxicity and harm potential section is a stub.
As such, it may contain incomplete or even dangerously wrong information. You can help by expanding or correcting it.
The toxicity and long-term health effects of recreational 2C-B-FLY do not seem to have been studied in any scientific context and the exact toxic dose is unknown. This is because 2C-B-FLY is a research chemical with a very limited history of human usage.
Anecdotal evidence from people within the community who have tried 2C-B-FLY suggests that there are no negative health effects attributed to simply trying the drug by itself at low to moderate doses and using it very sparingly (but nothing can be completely guaranteed). Independent research should always be done to ensure that a combination of two or more substances is safe before consumption.
It is strongly recommended that one use harm reduction practices when using this substance.
Tolerance and addiction potential
2C-B-FLY is not habit-forming and the desire to use it can actually decrease with use. It is most often self-regulating.
Tolerance to the effects of 2C-B-FLY are built almost immediately after ingestion. After that, it takes about 3 days for the tolerance to be reduced to half and 7 days to be back at baseline (in the absence of further consumption). 2C-B-FLY presents cross-tolerance with all psychedelics, meaning that after the consumption of 2C-B-FLY all psychedelics will have a reduced effect.
Although many psychoactive substances are reasonably safe to use on their own, they can quickly become dangerous or even life-threatening when combined with other substances. The list below includes some known dangerous combinations (although it cannot be guaranteed to include all of them). Independent research (e.g. Google, DuckDuckGo) should always be conducted to ensure that a combination of two or more substances is safe to consume. Some interactions listed have been sourced from TripSit.
- Lithium - Lithium is commonly prescribed in the treatment of bipolar disorder. There is a large body of anecdotal evidence that suggests taking it with psychedelics significantly increases the risk of psychosis and seizures. As a result, this combination is strictly discouraged.
- Cannabis - Cannabis has an unexpectedly strong and unpredictable synergy with the effects of psychedelics. Caution is advised with this combination as it can significantly increase the risk of adverse psychological reactions like anxiety, paranoia, panic attacks, and psychosis. Users are advised to start off with only a fraction of their normal cannabis dose and take long breaks between hits to avoid over intake.
- Stimulants (Amphetamine, cocaine, methylphenidate, ...) - Stimulants affect many parts of the brain and alter dopaminergic function. Combined with psychedelics, stimulation can turn into severe anxiety, panic, thought loops, and paranoia. This interaction may result in an elevated risk of mania and psychosis.
- Tramadol - Tramadol lowers the seizure threshold and psychedelics may act as triggers for seizures in susceptible individuals.
If 2C-B-FLY does have suspected MAO-altering effects, this could indicate that 2C-B-FLY is more likely to induce serotonin syndrome or general monoamine overload (especially at high dosages) than other serotonergic psychedelics. This may make it dangerous to combine it with MAOIs, stimulants and certain substances which modulate synaptic concentrations of neurotransmitters such as serotonin, dopamine and norepinephrine through unknown mechanisms. These substances include but are not limited to:
