2-Fluoroethamphetamine (2-FEA) is a synthetic molecule of the substituted amphetamine class. Molecules of the amphetamine class contain a phenethylamine core featuring a phenyl ring bound to an amino (NH2) group through an ethyl chain with an additional methyl substitution at Rα (i.e., amphetamines are alpha-methylated phenethylamines). 2-FEA contains an ethyl group bound to the terminal amine RN of the amphetamine core.
2-FEA is the N-ethylated homolog of 2-FA (2-fluoroamphetamine).
Although 2-FEA has not been formally studied on the same level as traditional amphetamines, it is roughly assumed that it most likely acts primarily as a triple reuptake inhibitor and/or releaser of the monoamine neurotransmitters serotonin, dopamine, and norepinephrine.
This indicates that 2-FEA effectively increases the levels of all the three major monoamine neurotransmitters dopamine, norepinephrine, and serotonin in the brain by acting as a releasing agent of said neurotransmitters and/or by binding to and partially blocking the transporter proteins that normally clear those molecules from the synaptic cleft after they have fulfilled their function of conducting a neural impulse. This transporter blockade allows these molecules to accumulate within core synaptic regions of the brain to extra-endogenous levels, resulting in a combination of relaxing, stimulating, disinhibiting and euphoric effects associated with entactogenic substituted amphetamines such as MDMA or 4-FA.
2-FEA is reported to be less stimulating and more euphoric in a fashion that is more compareable to 3-FEA, whilst also having fewer side effects at lower dosages, such as anxiety, nausea and high blood pressure, which it shares with 2-FMA.
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.
- Stimulation and Sedation - 2-FEA is reported to produce a paradoxical combination of sedating and stimulating effects. The sedating aspects are thought to be attributable to serotonin release. The stimulating effects are typically more prominent at dosages in and above the strong dosage range and tend to become prominent after the peak effects have subsided.
- Physical euphoria
- Tactile enhancement
- Stamina enhancement
- Abnormal heartbeat
- Increased heart rate
- Increased blood pressure
- Appetite suppression
- Dry mouth
- Frequent urination
- Increased bodily temperature
- Increased perspiration
- Pupil dilation
- Teeth grinding
- Temporary erectile dysfunction
- Restless legs
The visual effects of 2-FEA are usually less consistent and only mildly noticeable at higher dosages. They are somewhat comparable to deliriants and occur more readily in darker areas.
- Drifting (breathing and morphing) - This effect is usually subtle and barely noticeable and only occurs at higher dosages or when combined with cannabis.
- Brightness alteration - 2-FEA can make spaces seem brighter as a result of its pupil dilating effects.
- Transformations - This effect occurs very rarely, and typically only when the user has taken high doses, is coming down, or has been awake for unusually long periods. It is usually very mild when it does occur.
- Analysis enhancement
- Anxiety & Paranoia - This effect typically occurs with overly high doses or after redosing and staying awake for extended periods of time.
- Cognitive euphoria
- Compulsive redosing
- Ego inflation
- Emotion suppression
- Focus enhancement
- Increased libido
- Increased music appreciation
- Motivation enhancement
- Bodily control enhancement
- Thought acceleration
- Thought organization
- Time distortion - This can be described as the experience of time speeding up and passing much quicker than it usually would when sober.
- The effects which occur during the offset of a stimulant experience generally feel negative and uncomfortable in comparison to the effects which occurred during its peak. This is often referred to as a "comedown" and occurs because of neurotransmitter depletion. 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
The toxicity and long-term health effects of recreational 2-FEA use do not seem to have been studied in any scientific context and the exact toxic dosage is unknown. This is because 2-FEA has a very limited history of human usage.
Anecdotal reports from those who have tried 2-FEA suggest that there do not seem to be any negative health effects attributed to simply trying this substance at low to moderate doses by itself or using it sparingly (but nothing can be completely guaranteed).
It is strongly recommended that one use harm reduction practices when using this substance.
Tolerance and addiction potential
As with other stimulants, the chronic use of 2-FEA can be considered moderately addictive with a high potential for abuse and is capable of causing psychological dependence among certain users. When addiction has developed, cravings and withdrawal effects may occur if a person suddenly stops their usage.
Tolerance to many of the effects of 2-FEA develops with prolonged and repeated use. This results in users having to administer increasingly large doses to achieve the same effects. After that, it takes about 3 - 7 days for the tolerance to be reduced to half and 1 - 2 weeks to be back at baseline (in the absence of further consumption). 2-FEA presents cross-tolerance with all dopaminergic stimulants, meaning that after the consumption of 2-FEA all stimulants 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.
- Stimulants - 2-FEA can be potentially dangerous in combination with other stimulants as it can increase one's heart rate and blood pressure to dangerous levels.
- 25x-NBOMe & 25x-NBOH - Members of the 25x family are highly stimulating and physically straining. Combinations with stimulants should be avoided due to the risk of excessive stimulation. This can result in panic attacks, thought loops, seizures, increased blood pressure, vasoconstriction, and heart failure in extreme cases.
- Alcohol - Alcohol can be dangerous to combine with stimulants due to the risk of accidental over-intoxication. Stimulants mask the sedative effects of alcohol, which is the main factor people use to assess their degree of intoxication. Once the stimulant wears off, the depressant effects of alcohol are left unopposed, which can result in blackouts and respiratory depression. If combined, one should strictly limit themselves to only drinking a certain amount of alcohol per hour.
- DXM - Combinations with DXM should be handled with extreme care due to DXM's effects on serotonin and norepinephrine reuptake. This can lead to panic attacks, hypertensive crisis, or serotonin syndrome with stimulants that increase levels of serotonin (MDMA, methylone, mephedrone, etc.). Monitor blood pressure carefully and avoid strenuous physical activity.
- MDMA - The neurotoxic effects of MDMA may be increased when combined with other stimulants. There is also a risk of excessive heart strain.
- MXE - Combinations with MXE may dangerously elevate blood pressure and increase the risk of psychosis.
- Stimulants - 2-FEA can be potentially dangerous in combination with other stimulants as they can increase one's heart rate and blood pressure to dangerous levels.
- Cocaine - This combination may increase strain on the heart.
- Tramadol - Tramadol lowers the seizure threshold. Combinations with stimulants may further increase this risk.
- MDMA - The neurotoxic effects of MDMA may be increased when combined with amphetamines.
- MAOIs - This combination may increase the amount of neurotransmitters such as dopamine to dangerous or even fatal levels. Examples include syrian rue, banisteriopsis caapi, 2C-T-2, 2C-T-7, αMT, and some antidepressants.
- Cocaine - This combination may increase strain on the heart.

2-FEA is currently a gray area compound within all parts of the world, meaning its regulation lies in a legal gray area and that it is not known to be specifically illegal ("scheduled") within any country. However, people may still be charged for its possession under certain circumstances such as under analogue laws and with the intent to sell or consume.
- Canada: 2-FEA would be considered Schedule I as it is an analogue of Amphetamine.
- Germany: 2-FEA is controlled under the NpSG (New Psychoactive Substances Act) as of November 26, 2016. Production and import with the aim to place it on the market, administration to another person and trading is punishable. Possession is illegal but not penalized.
- New Zealand: 2-FEA is an amphetamine analogue, so is a Schedule 3 controlled substance in New Zealand.
- United Kingdom: 2-FEA is considered a Class A drug as a result of the amphetamine analogue clause of the Misuse of Drugs Act 1971.
