2-Fluoroethamphetamine (2-FEA) is a novel stimulant substance of the amphetamine class that produces classical stimulant effects such as stimulation, enhanced focus and euphoria when administered.

The exact effects of 2-FEA are not well known by its users with anecdotal reports suggesting only minimal activity and possible serotonergic qualities.

2-FEA is sold on the online research chemical market. It is strongly advised to use harm reduction practices if using this substance.

Chemistry

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 R_α (i.e., amphetamines are alpha-methylated phenethylamines). 2-FEA contains an ethyl group bound to the terminal amine R_N of the amphetamine core.

2-FEA is the N-ethylated homolog of 2-FA (2-fluoroamphetamine).

Pharmacology

Subjective effects

The effects of 2-FEA appear to be very subtle and difficult to characterize. Some reports suggest it is relatively mild and free of side effects in a similar fashion to 2-FA, while others note an increase in physical side effects or serotonergic activity reminiscent of 3-FEA.

Disclaimer: The effects listed below cite the Subjective Effect Index (SEI), a literature which relies on collected 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 with higher doses and may include serious injury or death.

Physical effects

• • Stimulation and Sedation - 2-FEA is reported to produce a paradoxical combination of sedating and stimulating effects. The sedating aspects are perhaps 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
  • Bronchodilation
  • Dehydration
  • Dry mouth
  • Frequent urination
  • Increased bodily temperature
  • Increased perspiration
  • Nausea
  • Pupil dilation
  • Teeth grinding
  • Temporary erectile dysfunction
  • Vasoconstriction
  • Restless legs

Visual effects

• 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.

  Distortions

  • 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.

  Hallucinatory states

  • 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.

Cognitive effects

• The cognitive effects of 2-FEA are generally very subtle and consist of mild to moderate stimulation.
  • 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
  • Delusion
  • Disinhibition
  • Ego inflation
  • Emotion suppression
  • Focus enhancement
  • Increased libido
  • Increased music appreciation
  • Motivation enhancement
  • Bodily control enhancement
  • Thought acceleration
  • Thought organization
  • Wakefulness
  • Time distortion - This can be described as the experience of time speeding up and passing much quicker than it usually would when sober.

After effects

• 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:
  • Anxiety
  • Cognitive fatigue
  • Delusion
  • Depersonalization
  • Depression
  • Headaches
  • Irritability
  • Motivation suppression
  • Psychosis
  • Thought deceleration
  • Wakefulness

Toxicity and harm potential

Further information: Research chemicals § 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.

Dangerous interactions

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.
