Butylone (also known as β-keto-N-methylbenzodioxolylbutanamine, βk-MBDB, or B1) is a synthetic entactogen and stimulant substance of the cathinone class. It is the β-keto analog of MBDB and the substituted methylenedioxy analogue of buphedrone.

As a designer drug, it is commonly sold on the street along with ethylone as a substitute or counterfeit for MDMA and methylone (all of which have collectively come to be referred to as "Molly") due to methylone's declining availability on the research chemical market. However, in spite of behavioral and pharmacological similarities between butylone and MDMA, the observed subjective effects of both substances are not completely identical.[1]

Subjective effects include stimulation, thought acceleration, motivation enhancement, increased libido, appetite suppression, and euphoria, Butylone is reported to be less potent than its relatives methylone and ethylone as well as possessing more classic stimulant as opposed to entactogenic effects.

Butylone has a very short history of human use and very little data exists about its pharmacological properties, metabolism, and toxicity. It is highly advised to use harm reduction practices if using this substance.

Chemistry

Butylone, or β-keto-N-methylbenzodioxolylbutanamine, is a synthetic molecule of the cathinone family. Cathinones are structurally similar to amphetamines in that they contain a phenethylamine core featuring a phenyl ring bound to an amino (NH2) group through an ethyl chain with an additional ethyl substitution at Rα. Cathinones such as butylone are alpha-methylated phenethylamines (i.e. amphetamines) but differ from them with the addition of a ketone functional group (a carbonyl group at Rβ). Butylone contains a methyl substitution at RN, a substitution which is shared with MDEA, ethylone, 4-MEC, and certain other stimulants and entactogens. Additionally, butylone contains substitutions at R3 and R4 of the phenyl ring with oxygen groups. These oxygen groups are incorporated into a methylenedioxy ring through a methylene chain. Butylone shares this methylenedioxy ring with MDA, MDAI and MDMA.

Pharmacology

Butylone acts as a mixed reuptake inhibitor/releasing agent of serotonin, norepinephrine, and dopamine.[2][3] These are the neurotransmitters in charge of pleasure, reward, motivation and focus. This is done by inhibiting the reuptake and reabsorption of the neurotransmitters after they have performed their function of transmitting a neural impulse, essentially allowing them to accumulate and be reused, causing physically stimulating and euphoric effects.

In comparison to methylone, it has approximately over 4x lower affinity for the norepinephrine transporter, while its affinity for the serotonin and dopamine transporters is similar.[4][3] The results of these differences in pharmacology relative to MDMA is that butylone, like its close analog ethylone is less potent in terms of dose, has more balanced catecholaminergic effects relative to serotonergic, and behaves more like a reuptake inhibitor like methylphenidate than a releaser like amphetamine; however, butylone still has relatively robust releasing capabilities.[4]

Subjective effects

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 ☠.

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

The toxicity and long-term health effects of recreational butylone use do not seem to have been studied in any scientific context and the exact toxic dosage is unknown. This is because butylone has very little history of human usage. Anecdotal evidence from people who have tried butylone within the community suggests that there do not seem to be strong adverse effects attributed to using this substance at low to moderate doses and sparingly.

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 butylone 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 butylone 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). Butylone presents cross-tolerance with all dopaminergic stimulants, meaning that after the consumption of butylone all stimulants will have a reduced effect.

Psychosis

Main article: Stimulant psychosis

Abuse of compounds within the stimulant 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).[5] A review on treatment for amphetamine, dextroamphetamine, and methamphetamine abuse-induced psychosis states that about 5–15% of users fail to recover completely.[5][6] The same review asserts that, based upon at least one trial, antipsychotic medications effectively resolve the symptoms of acute amphetamine psychosis.[5] Psychosis very rarely arises from therapeutic use.[7]

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.

  • 25x-NBOMe & 25x-NBOH - 25x compounds are highly stimulating and physically straining. Combinations with Butylone 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.
  • Alcohol - 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.
  • DXM - 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.
  • MDMA - 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).
  • MXE - Some reports suggest combinations with MXE may dangerously increase blood pressure and increase the risk of mania and psychosis.
  • Dissociatives - Both classes carry a risk of delusions, mania and psychosis, and these risk may be multiplied when combined.
  • Stimulants - Butylone may be dangerous to combine with other stimulants like cocaine as they can increase one's heart rate and blood pressure to dangerous levels.
  • Tramadol - Tramadol is known to lower the seizure threshold[8] and 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.
