Summary sheet: 4-FMC

Template:SubstanceBox/Flephedrone

Flephedrone, also known as 4-fluoromethcathinone (4-FMC), is a synthetic stimulant drug of the amphetamine and cathinone classes.

Slang names for the drug include drone. It is chemically similar to the cathinone compounds found in the khat plant of eastern Africa. It comes in the form of a powder, which users can swallow, snort, inject or insert rectally producing effects which are somewhat similar to that MDMA, amphetamine, and cocaine.

Chemistry

Flephedrone, or 4-fluoromethcathinone, is a synthetic molecule of the cathinone family. Cathinones are structurally similar to amphetamines, they 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. Amphetamines and cathinones are alpha-methylated phenethylamines, cathinones contain an additional carbonyl group at R1. Flephedrone contains an additional fluoro substitutions at RN and a methyl substitution at R4 of its phenyl ring.

Pharmacology

Given its chemical structure, flephedrone is likely to act as a releasing agent and a reuptake inhibitor for monoamine neurotransmitters such as dopamine, serotonin and noradrenaline. Flephedrone is likely to have a similar pharmacological profile to mephedrone.

Subjective effects

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.

Physical effects

  • Spontaneous tactile sensations - The "body high" of flephedrone can be described as a moderate to extreme euphoric tingling sensation that encompasses the entire body. It is capable of becoming overwhelmingly pleasurable at higher dosages. This sensation maintains a consistent presence that steadily rises with the onset and hits its limit once the peak has been reached.
  • Stimulation - In terms of its effects on the user's physical energy levels, flephedrone is commonly considered to be extremely stimulating and energetic. This encourages activities such as running, climbing and dancing. The particular style of stimulation which flephedrone presents can be described as forced. This means that at higher dosages it becomes difficult or impossible to keep still, as jaw clenching, involuntarily bodily shakes and vibrations become present, resulting in an extreme unsteadiness of the hands and a general lack of motor control.
  • Vibrating vision - A person's eyeballs may begin to spontaneously wiggle back and forth in a rapid motion, causing vision to become blurry and temporarily out of focus-- a condition known as nystagmus.
  • Dehydration - Dry mouth and dehydration are a universal experience with flephedrone and are a product of an increased heart rate and extreme motivation to engage in strenuous physical activities. While it is important to avoid becoming dehydrated, especially when out dancing in a hot environment, there is a potential possibility of suffering from water intoxication through over-drinking so it is advised that users simply sip at water and never over drink.
  • Difficulty urinating - Higher doses of flephedrone result in an overall difficulty when it comes to urination, an effect that is completely temporary and harmless.
  • Vasoconstriction
  • Tactile enhancement
  • Increased heart rate - Tachycardia has been associated with flephedrone usage.
  • Increased perspiration
  • Increased blood pressure
  • Body odor alteration
  • Teeth grinding - This component can be considered to be less intense when compared with that of MDMA.

Cognitive effects

The cognitive effects of flephedrone can be broken down into several components which progressively intensify proportional to dosage. The general head space of mephedrone is described by many as one of extreme mental stimulation and powerful euphoria. It contains a large number of typical stimulant cognitive effects.

The most prominent of these cognitive effects generally include:

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:

Experience reports

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

Almost nothing is known about the long-term effects of flephedrone due to its short history of its use. The exact toxic dosage is unknown.

It is strongly recommended that one use harm reduction practices when using this drug.

Tolerance and addiction potential

As with other stimulants, the chronic use of mephedrone 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 flephedrone 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). Flephedrone presents cross-tolerance with all dopaminergic stimulants, meaning that after the consumption of mephedrone 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 taken with other substances. The following lists some known dangerous combinations, but cannot be guaranteed to include all of them. Independent research 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.

  • MDMA - The neurotoxic effects of MDMA may be increased when combined with other amphetamines.
  • Cocaine - This combination may increase strain on the heart.
  • Stimulants - 4-FMC 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.[1] Combinations with stimulants may further increase this risk.

Serotonin syndrome risk

Combinations with the following substances can cause dangerously high serotonin levels. Serotonin syndrome requires immediate medical attention and can be fatal if left untreated.

Legal issues

  • United Kingdom: It is illegal to produce, supply, or import this drug under the Psychoactive Substance Act, which came into effect on May 26th, 2016. [3]
