3-FMA crystal rocks – More information
3-Fluoromethamphetamine (also known as 3-FMA) is a novel synthetic ring-substituted fluorinated amphetamine compound that produces entactogenic and stimulant effects when administered. Following the introduction of 3-FEA, 3-FMA subsequently entered the designer drug market as a compound structurally related to a series of fluorinated substituted amphetamines that originally included compounds such as 2-FMA, 3-FA, 4-FMA, 4-FA.
Like its parent compound 3-FA, the pharmacological, toxicological, and subjective effects of 3-FMA in humans have yet to be mapped out in detail. Early reports have so far characterized 3-FMA as a moderately potent serotonin-dominant triple monoamine releaser (or reuptake inhibitor) that produces a relatively short-lived balance of entactogenic and stimulant effects. Based on related compounds, it is not unreasonable to speculate that this compound possesses neurotoxic, cardiotoxic and other potential to-be-discovered toxic properties, which is why extreme caution is advised.
3-FMA has an extremely short history of recreational use and has yet to be documented being sold on the streets. It has recently been made available for sale on the gray market as a research chemical through online vendors. The appearance of it as well as 3-FEA on the research chemicals market coincides with the increased efforts to control the popular entactogenic stimulant 4-FA.
Due to its potent psychostimulant effect, likely habit-forming properties as well as unknown toxicity profile, it is strongly recommended that one use proper harm reduction practices if choosing to use this substance.

3-FMA, or 3-fluoromethamphetamine, is a synthetic molecule of the amphetamine family. Molecules of the amphetamine family contain a phenethylamine core featuring a phenyl ring bound to an amino (NH2) group through an methyl chain with an additional methyl substitution at Rα (i.e. amphetamines are alpha-methylated phenethylamines). 3-FMA is the 3-position fluorinated analog methamphetamine; however, it is currently speculated to behave more in the manner of shorter-lived entactogenic stimulant. Additionally, is is also a positional isomer of 2-FMA and 4-FMA.
The toxicity and long-term health effects of human recreational 3-FMA use do not seem to have been studied in any scientific context and the exact toxic dosage is unknown. This is because 3-FMA has an extremely short history of human usage, becoming available only in mid-2017. Anecdotal evidence from people who have tried 3-FMA within the community suggests that there do not seem to be any negative health effects attributed to simply trying this drug at low to moderate doses by itself and using it sparingly (but nothing can be completely guaranteed).
Due to its putative serotonin-releasing and entactogenic properties, it is possible that 3-FMA may display excess activity at the 5-HT2b receptor, which, would make it cardiotoxic with long-term use as seen in other 5-HT2b agonists such as fenfluramine and MDMA.
It is perhaps worth noting that in the field of medicinal chemistry, the fluorine substitution is sometimes seen as desirable in central nervous system pharmaceutical agents, and is a common practice due to the corresponding increase in lipophilicity granted by the substitute.
It is strongly recommended that one use harm reduction practices when using this drug.
Although it still remains to be seen, the chronic use of 3-FMA likely can be considered moderately addictive with a high potential for abuse and capable of causing psychological dependence among a certain population of users. When dependence or addiction has developed, cravings and withdrawal effects may occur if a person suddenly stops their usage.
Tolerance to many of the effects of 3-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 – 10 days to be back at baseline (in the absence of further consumption). 3-FMA presents cross-tolerance with all dopaminergic and serotonergic stimulants and entactogens, meaning that after the consumption of 3-FMA all stimulants will have a reduced effect (including atypical stimulants one might not expect, like MDMA or amphetamine due to its reliance on dopamine and norepinephrine to exert its full euphoric effect).
Abuse of compounds within the amphetamine chemical 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. Psychosis very rarely arises from therapeutic use.
3-FMA is currently a grey area compound within all parts of the world, meaning its regulation lies in a legal grey 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 intent to sell or consume.
