|Summary sheet: 2-FMA|
|Routes of Administration|
2-Fluoromethamphetamine (2-FMA) is a novel stimulant substance of the amphetamine class. 2-FMA is a member of a group known as substituted amphetamines, which include compounds like 2-FA, 3-FA, and 4-FMA. 2-FMA produces its stimulant effects through action at dopamine and norepinephrine receptors in the brain.
2-FMA is commonly taken either orally or via insufflation and is reported to be highly unpleasant to vaporize. It is commonly compared to lisdexamfetamine (Vyvanse) in its duration, potency and efficacy as a study or productivity aid. Despite its popularity as a research chemical study aid, little is known about the effects that may accompany its long-term use as a substitute for prescription stimulants.
Typical effects include those of a classical stimulant such as stimulation, enhanced focus and euphoria. A substantial increase in adverse effects like high blood pressure and increased heart rate are often reported for dosages above the heavy dosage range.

2-Fluoromethamphetamine (2-FMA) 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-FMA contains a methyl group bound to the terminal amine RN of the amphetamine core, a substitution it shares with methamphetamine.
Although 2-FMA has not been formally studied on the same level as traditional amphetamines, it is thought that it acts as both a dopamine and norepinephrine releasing agent. This means it effectively increases the levels of the norepinephrine and dopamine in the brain by binding to and partially blocking the transporter proteins that normally remove them from the synaptic cleft. This allows dopamine and norepinephrine to accumulate within the brain, resulting in stimulating and euphoric effects.
In comparison to other substituted amphetamines, 2-FMA is reported to be relatively free of side effects such as nausea, high blood pressure, anxiety and an uncomfortable offset ("comedown"). It is considered to be a functional stimulannt for performing general productivity tasks in a manner similar to amphetamine or lisdexamfetamine (Vyvanse). However, at higher doses, it typically loses its productivity and focus-enhancing effects and begins to take on a recreational character due to the distracting euphoria that it can produce.
The effects listed below are based upon the subjective effects index and personal experiences of PsychonautWiki contributors. These effects should be taken with a grain of salt and will rarely (if ever) occur all at once, but heavier doses will increase the chances of inducing a full range of effects. Likewise, adverse effects become much more likely on higher doses and may include serious injury or death.
- Stimulation - In terms of its effects on the physical energy levels of the user, 2-FMA is usually considered to be very energetic and stimulating in a fashion that is slightly weaker to that of methamphetamine, but stronger than that of modafinil, caffeine, and methylphenidate. The particular style of stimulation which 2-FMA presents can be described as forced. This means that, at higher dosages, it becomes difficult or impossible to keep still as jaw clenching, involuntary bodily shakes and vibrations become present, resulting in extreme shaking of the entire body, unsteadiness of the hands, and a general loss of fine motor control.
- 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 - This effect is typically experienced only at higher dosages and is more prominent on the comedown.
- Teeth grinding - This component can be considered to be less intense when compared with that of MDMA.
- Temporary erectile dysfunction
- Restless legs
The visual effects of 2-FMA 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-FMA 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:

Toxicity and harm potential
The toxicity and long-term health effects of recreational 2-FMA use do not seem to have been studied in any scientific context and the exact toxic dosage is unknown. This is because 2-FMA has a very limited history of human usage.
Anecdotal reports from those who have tried 2-FMA 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-FMA 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-FMA 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-FMA presents cross-tolerance with all dopaminergic stimulants, meaning that after the consumption of 2-FMA all stimulants will have a reduced effect.
The use of compounds in the amphetamine class at high dosages for prolonged periods of time can potentially result in a stimulant psychosis that may present with a variety of symptoms (e.g., paranoia, hallucinations, or delusions). A review on treatment for amphetamine, dextroamphetamine, and methamphetamine abuse-induced psychosis states that about 5–15% of users fail to recover completely. The same review asserts that, based upon at least one trial, antipsychotic medications effectively resolve the symptoms of acute amphetamine psychosis.
Although many psychoactive substances are safe to use on their own, they can quickly become dangerous or even life-threatening when combined with other substances. The following lists some known dangerous combinations, but may not include all of them. A combination that appears to be safe in low doses can still increase the risk of injury or death. Independent research should always be conducted to ensure that a combination of two or more substances is safe to consume.
- Stimulants - 2-FMA 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 strictly avoided due to DXM's effects on serotonin and dopamine reuptake. This can lead to panic attacks, hypertensive crisis, or serotonin syndrome.
- MXE - Combinations with MXE may dangerously elevate blood pressure and increase the risk of psychosis.
- 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.
