Summary sheet: 5-MAPB

5-(2-methylaminopropyl)benzofuran (abbreviated 5-MAPB) is a synthetic entactogen of the substituted benzofuran class of chemicals, which are known to produce euphoric, entactogenic, stimulating and mildly hallucinogenic effects. These include such MDA-inspired substances as 5-APB, 6-APB and 5-EAPB, among others. 5-MAPB is the N-methylated form of 5-APB, analogously to how MDMA is the N-methylated form of MDA.

This compound is known for its stimulating, euphoric and entactogenic effects that is capable of acting a quasi-substitute for MDMA proper, which has resulted in its rise in popularity as a research chemical that is easily accessible through the use of online vendors. It has been sold as a designer drug since 2010.

5-MAPB is commonly found as the succinate and hydrochloride salt. The hydrochloride salt is 10% more potent by mass so doses should be adjusted accordingly.

Chemistry

5-(2-methylaminopropyl)benzofuran, or 5-MAPB, is a substituted benzofuran and phenethylamine. It is comprised of an N-methylated ethylamine chain and a furan ring attached to a central benzene ring. It can also be classified as a derivative of methamphetamine because the N-methylated ethylamine chain is alpha methylated in an analagous manner. 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. The oxygen atom in the furan ring is placed at the 5 position, which generally constitutes more stimulating effects than when the oxygen is placed at the 6 position, which usually renders it more psychedelic in effect.

Pharmacology

5-MAPB is a triple reuptake inhibitor for the monoamines norepinephrine, dopamine and serotonin as well as being an agonist for the 5-HT_2A and 5-HT_2B receptors. It has also been speculated that 5-MAPB acts as a releasing agent for the previously mentioned neurotransmitters.

As a result, releasing agents such as 5-MAPB may exert their activity by effectively boosting the levels of the serotonin, norepinephrine and dopamine neurotransmitters in the brain by binding to and partially blocking the transporter proteins that normally clear and reuptake those monoamines from the synaptic cleft. This allows serotonin, dopamine and norepinephrine to accumulate within various reward and cognition-related areas in the brain, resulting in stimulating and euphoric effects.

Subjective effects

This subjective effects section is a stub. As such, it is still in progress and may contain incomplete or wrong information. You can help by expanding or correcting it.

Disclaimer: The effects listed below cite the Subjective Effect Index (SEI), an open research literature based on anecdotal user reports and the personal analyses of PsychonautWiki contributors. As a result, they should be viewed with a healthy degree of skepticism.

It is also worth noting that these effects will not necessarily occur in a predictable or reliable manner, although higher doses are more liable to induce the full spectrum of effects. Likewise, adverse effects become increasingly likely with higher doses and may include addiction, severe injury, or death ☠.

Physical effects

• Stimulation - In terms of its effects on the user's physical energy levels, 5-MAPB is commonly regarded as significantly less stimulating and energizing than MDMA, while still retaining its core entactogenic effects. Unlike MDMA, which encourages activities such as running, climbing and dancing in a way that makes it a popular choice for musical events such as festivals and raves. The distinct style of stimulation which 5-MAPB presents can be described as mildly to moderately forced, trending more towards sedation and relaxation. This means that at higher doses, it becomes difficult or impossible to keep still as jaw clenching, involuntarily body shakes and vibrations become present, resulting in an extreme unsteadiness of the hands and a general lack of motor control, though to a far lesser degree than with MDMA.
• Increased heart rate
• Dehydration
• Appetite suppression
• Nausea
• Temporary erectile dysfunction
• Increased perspiration

Cognitive effects

• Empathy, love, and sociability enhancement
• Focus enhancement
• Thought acceleration
• Analysis enhancement
• Wakefulness
• Memory enhancement
• Motivation enhancement
• Euphoria
• Compulsive redosing
• Increased music appreciation

Visual effects

• Acuity enhancement

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
• Depression
• Irritability
• Motivation suppression
• Thought deceleration
• Wakefulness

Toxicity and harm potential

Main article: Research chemicals § Toxicity and harm potential

The toxicity and long-term health effects of recreational 5-MAPB use do not seem to have been studied in any scientific context and the exact toxic dosage is unknown. This is because 5-MAPB has very little history of human usage. Anecdotal evidence from people who have tried 5-MAPB within the community 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 and using it sparingly (but nothing can be completely guaranteed).

5-MAPB's notable agonism at the serotonin-2b (5-HT2b) receptor (which has been associated with cardiovalvulopathy) suggests that it would be cardiotoxic with long-term use, as seen in other 5-HT2B agonists such as fenfluramine and MDMA.

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

Tolerance and addiction potential

As with other entactogenic stimulants, the chronic use of 5-MAPB 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 5-MAPB 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). 5-MAPB presents cross-tolerance with [[Cross-tolerance::all dopaminergic stimulants]], meaning that after the consumption of 5-MAPB all stimulants will have a reduced effect.

Psychosis

Main article: Stimulant psychosis

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.

Dangerous interactions

Warning: Many psychoactive substances that are reasonably safe to use on their own can suddenly become dangerous and even life-threatening when combined with certain other substances. The following list provides some known dangerous interactions (although it is not guaranteed to include all of them).

Always conduct independent research (e.g. Google, DuckDuckGo, PubMed) to ensure that a combination of two or more substances is safe to consume. Some of the listed interactions have been sourced from TripSit.

• "[[DangerousInteraction" contains a listed "[" character as part of the property label and has therefore been classified as invalid.]] & "[[DangerousInteraction" contains a listed "[" character as part of the property label and has therefore been classified as invalid.]] - 25x compounds are highly stimulating and physically straining. Combinations with 5-MAPB should be strictly avoided due to the risk of excessive stimulation and heart strain. This can result in increased blood pressure, vasoconstriction, panic attacks, thought loops, seizures, and heart failure in extreme cases.
• "[[UncertainInteraction" contains a listed "[" character as part of the property label and has therefore been classified as invalid.]] - Combining alcohol with stimulants can be dangerous due to the risk of accidental over-intoxication. Stimulants mask alcohol's depressant effects, which is what most people use to assess their degree of intoxication. Once the stimulant wears off, the depressant effects will be left unopposed, which can result in blackouts and severe respiratory depression. If mixing, the user should strictly limit themselves to only drinking a certain amount of alcohol per hour.
• "[[UnsafeInteraction" contains a listed "[" character as part of the property label and has therefore been classified as invalid.]] - Combinations with DXM should be avoided due to its inhibiting effects on serotonin and norepinephrine reuptake. There is an increased risk of panic attacks and hypertensive crisis, or serotonin syndrome with serotonin releasers (MDMA, methylone, mephedrone, etc.). Monitor blood pressure carefully and avoid strenuous physical activity.
• "[[UnsafeInteraction" contains a listed "[" character as part of the property label and has therefore been classified as invalid.]] - Any neurotoxic effects of MDMA are likely to be increased when other stimulants are present. There is also a risk of excessive blood pressure and heart strain (cardiotoxicity).
• "[[UncertainInteraction" contains a listed "[" character as part of the property label and has therefore been classified as invalid.]] - Some reports suggest combinations with MXE may dangerously increase blood pressure and increase the risk of mania and psychosis.
• "[[UncertainInteraction" contains a listed "[" character as part of the property label and has therefore been classified as invalid.]] - Both classes carry a risk of delusions, mania and psychosis, and these risk may be multiplied when combined.
• "[[UnsafeInteraction" contains a listed "[" character as part of the property label and has therefore been classified as invalid.]] - 5-MAPB may be dangerous to combine with other stimulants like cocaine as they can increase one's heart rate and blood pressure to dangerous levels.
• "[[DangerousInteraction" contains a listed "[" character as part of the property label and has therefore been classified as invalid.]] - Tramadol is known to lower the seizure threshold and combinations with stimulants may further increase this risk.
• "[[DangerousInteraction" contains a listed "[" character as part of the property label and has therefore been classified as invalid.]] - This combination may increase the amount of neurotransmitters such as dopamine to dangerous or even fatal levels. Examples include syrian rue, banisteriopsis caapi, and some antidepressants.
• Stimulants - The neurotoxic effects of 5-MAPB may be increased when combined with other stimulants.
• Cocaine - This combination may increase strain on the heart.

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.

• MAOIs - Such as banisteriopsis caapi, syrian rue, phenelzine, selegiline, and moclobemide.
• Serotonin releasers - Such as MDMA, 4-FA, methamphetamine, methylone and αMT.
• SSRIs - Such as citalopram and sertraline
• [[Wikipedia:SNRIs|DangerousInteraction::SNRIs]] - Such as tramadol and venlafaxine
• 5-HTP
