2-FMA (2-Fluoromethamphetamine) Powder

---

2-Fluoromethamphetamine (2-FMA) is a novel stimulant substance belonging to the amphetamine class. It is a structural analog of methamphetamine and is related to other compounds such as 2-FA, 3-FA, and 4-FMA. The stimulant effects of 2-FMA are mediated through its action at dopamine and norepinephrine receptors in the brain.

Market Introduction

The sale of 2-FMA on the online research chemical market was first reported in August 2007, appearing alongside other fluorinated amphetamines like 2-FA and 4-FA. Despite its presence in the market, 2-FMA remains largely unknown in clinical and research literature.

Subjective Effects

Users report a range of subjective effects from 2-FMA, including stimulation, focus enhancement, motivation enhancement, increased libido, appetite suppression, and euphoria. It is commonly administered either orally or via insufflation; however, vaporization is considered highly unpleasant and dangerous due to the risk of breaking the carbon-fluoride bond, which can produce toxic byproducts. Many users compare 2-FMA to lisdexamfetamine (Vyvanse) in terms of duration, potency, and efficacy as a productivity aid. Notably, adverse effects such as high blood pressure and increased heart rate are often reported at dosages exceeding the heavy dosage range.

Chemistry

2-Fluoromethamphetamine (2-FMA) is a synthetic molecule within the substituted amphetamine class. The amphetamine family is characterized by a phenethylamine core, which features a phenyl ring connected to an amino (NH2) group through an ethyl chain, with an additional methyl substitution at Rα. 2-FMA contains a methyl group bound to the terminal amine RN of the amphetamine core, a substitution it shares with methamphetamine. As the 2-position fluorinated analog of methamphetamine, 2-FMA is also the N-methylated homolog of 2-FA (2-fluoroamphetamine).

Subjective Effects Overview

Compared to other substituted amphetamines, 2-FMA is often reported to have fewer side effects, such as nausea, high blood pressure, anxiety, and uncomfortable comedowns. It is regarded as a functional stimulant for general productivity tasks, similar to amphetamine or lisdexamfetamine (Vyvanse). However, at higher doses, it tends to lose its productivity and focus-enhancing effects, taking on a more recreational character due to the distracting euphoria it can induce. Many users report a ceiling effect at high doses, where uncomfortable stimulant effects become more pronounced.

Physical Effects

• Stimulation: 2-FMA is considered very energetic and stimulating, slightly weaker than methamphetamine but stronger than modafinil, caffeine, and methylphenidate. Users often describe the stimulation as "clean," though it can lead to involuntary bodily movements and a loss of fine motor control at higher doses.
• Physical euphoria: More prominent at higher doses, typically weaker than that of other stimulants.
• Tactile enhancement
• Stamina enhancement
• Increased heart rate and blood pressure
• Appetite suppression
• Dehydration and dry mouth
• Frequent urination
• Increased bodily temperature and perspiration
• Nausea
• Pupil dilation: More noticeable at higher doses, especially during the comedown.
• Teeth grinding: More intense at higher doses, but less so compared to MDMA.
• Temporary erectile dysfunction
• Vasoconstriction
• Restless legs

Cognitive Effects

• Analysis enhancement
• Anxiety and paranoia: Typically occurs with high doses or after prolonged use.
• Cognitive euphoria
• Compulsive redosing
• Delusion and disinhibition
• Ego inflation and emotion suppression
• Focus enhancement
• Increased libido and music appreciation
• Motivation enhancement
• Bodily control enhancement
• Thought acceleration and organization
• Wakefulness
• Time distortion: Users may experience time passing more quickly than usual when sober.

Visual Effects

The visual effects of 2-FMA are generally less consistent and only mildly noticeable at higher doses. They can be somewhat comparable to those of deliriants and are more likely to occur in darker environments.

• Distortions: Users may experience subtle effects such as drifting (breathing and morphing), which typically occurs at higher doses or when combined with cannabis.
• Brightness alteration: 2-FMA can make spaces appear brighter due to its pupil-dilating effects.
• Hallucinatory states: Transformations are rare and usually only occur at high doses, during the comedown, or after extended wakefulness. When they do occur, they are typically mild.
