MDPV

Skull and crossbones darktextred2.png

MDPV may cause psychosis, mania and addiction at a significantly higher rate than other stimulants.

Due to its unusually long duration, extreme potency, and compulsive nature, it is strongly discouraged to abuse this substance in high doses, multiple days in a row, or in combination with other drugs known to increase the risk of psychosis. MDPV is one of several designer drugs that has been sold as "bath salt" both in the US and in Europe; In a four-year period between September 2009 and August 2013, the European Union (EU) reported a concerningly high number of MDPV-related deaths, reaching 99.[1]

3,4-Methylenedioxypyrovalerone (also known as MDPV, and Monkey Dust[2]) is a novel lesser-known stimulant substance of the cathinone and pyrrolidine classes. It is known to be one of the most powerful and potent stimulants. MDPV is thought to act primarily as a norepinephrine-dopamine reuptake inhibitor (NDRI).

MDPV was first developed in the 1960s by a team at Boehringer Ingelheim.[3] It was claimed to have potential to be an alternative for racemic amphetamine and, despite showing some desirable qualities such as reduced toxicity as compared to amphetamine, was chosen to not be developed as a medicinal drug.[4]

MDPV remained an obscure stimulant until around 2004, when it was reportedly first made available to the public as a designer drug. Products labeled as "bath salts" containing MDPV were previously sold as recreational drugs in gas stations and convenience stores in the United States, similar to the marketing strategy of Spice and K2 as incense.[citation needed]

Subjective effects include stimulation, disinhibition, increased libido, appetite suppression, and powerful euphoria.

Several incidents of psychological and physical harm have been attributed to the use of MDPV, including an unusually large number of fatalities. A total of 107 non-fatal intoxications and 99 analytically confirmed deaths related to MDPV between September 2009 and August 2013 were reported by nine European countries.[1]

It is highly advised to use harm reduction practices if using this substance.

Chemistry

MDPV, or 3,4-Methylenedioxypyrovalerone, is a synthetic stimulant of the cathinone and pyrrolidine classes. MDPV is the 3,4-methylenedioxy ring-substituted analog of the compound a-PVP, developed in the 1960s, which has been used for the treatment of chronic fatigue and as an anorectic, but caused problems of abuse and dependence.[3]

However, despite some shared structural features, the effects of MDPV bear little resemblance to other methylenedioxy phenylalkylamine derivatives such as 3,4-methylenedioxy-N-methylamphetamine (MDMA), instead producing primarily classical stimulant effects with only mild entactogenic qualities.[5]

MDPV is structurally related to cathinone, an active alkaloid found in the khat plant, 3,4-methylenedioxymethamphetamine (MDMA), methamphetamine, and other schedule I phenethylamines. MDPV, like some other substances in this class, is a central nervous system (CNS) stimulant. MDPV is also reported to have hallucinogenic effects.[6]

Pharmacology

MDPV is thought to act primarily as a potent norepinephrine-dopamine reuptake inhibitor. Reduced re-uptake of norepinephrine and dopamine results in higher concentrations of the two catecholamine neurotransmitters in the synaptic cleft, or gap between neurons.

The result of this inhibition is an enhanced and prolonged concentration and resulting post-synaptic effect of dopaminergic and noradrenaline signaling at dopamine and norepinephrine receptors on the receiving neuron. Serotonin also plays a role, although to a much lesser degree. This sudden increase in neurotransmitter concentration in the brain is thought to be responsible for the high that MDPV produces.

Mainly possessing re-uptake inhibiting qualities and not releasing qualities, MDPV could be considered more like cocaine or methylphenidate than amphetamine in method of action.[7] In contrast, amphetamine acts primarily as an agonist to release dopamine and noradrenaline indirectly via activation of the TAAR1 receptor.

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 ☠.

Physical effects
 

Auditory effects
 

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: It should be noted that many users consider the after effects of MDPV to be significantly more unpleasant if compulsively redosed.[8][9]

Toxicity and harm potential

 

This toxicity and harm potential section is a stub.

As a result, it may contain incomplete or even dangerously wrong information! You can help by expanding upon or correcting it.
Note: Always conduct independent research and use harm reduction practices if using this substance.

MDPV has a relatively short history of human use, with very few mentions concerning the use thereof before 2004. Although once considered a potential alternative to existing stimulants with a lower risk for toxicity, human MDPV administration has not been extensively studied in a clinical setting for many decades. Despite this, several recent studies on cases of persisting psychosis caused by chronic use of MDPV show promising rates of recovery among individuals who are treated with certain antipsychotics and first-line antihistamines.[13] There is currently no conclusive data concerning the neurotoxicity of MDPV in the human brain.

Anecdotal evidence from those who have tried MDPV in the community suggest that there are no negative health effects associated with the substance if simply taken at low doses by itself and when used sparingly (but nothing can be completely guaranteed).

Data taken from in-vitro and in-vivo studies have indicated that MDPV shares similar properties to methamphetamine and cocaine; in fact, MDPV is more potent than these two stimulants in a number of varying ways.[14] The over-excitation of dopamine and noradrenaline caused by MDPV use, combined with MDPV's potential inability to create compensatory serotonergic activity, sets the stage for a number of hostile and psychotic reactions to the drug. These hostile tendencies have been witnessed in emergency response situations, and have also seen wide television coverage in the past, after an individual under the influence of MDPV viciously assaulted an innocent bystander. It is uncertain if the individual had any pre-existing mental disorders or if he was under the influence of any other drugs.[citation needed]

Lethal dosage

The exact lethal dosage of MDPV is unknown and no formal studies have been carried out in humans. For sake of reference, one report placed the lethal dosage for a 39 year old male at 0.4 micrograms per millilitre or greater following the results of a post mortem,[15] but this data is far too individually unique and the variables simply too diverse to derive any kind of meaningful information from it. MDPV may be quantified in blood, plasma or urine by gas chromatography-mass spectrometry or liquid chromatography-mass spectrometry to confirm a diagnosis of poisoning in hospitalized patients or to provide evidence in a medicolegal death investigation. Blood or plasma MDPV concentrations are expected to be in a range of 10–50 μg/L in persons using the drug recreationally, >50 μg/L in intoxicated patients, and >300 μg/L in victims of acute overdose.[16]

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

Dependence and abuse potential

More so than other stimulants, the chronic use of MDPV can be considered highly 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. Addiction is a serious risk among users of MDPV as it easily causes compulsive redosing and causes highly unpleasant comedown symptoms.

Psychosis

Main article: Stimulant psychosis

User reports indicate that chronic abuse or single exposure overdose of MDPV can potentially lead to psychosis more readily than the vast majority of stimulants. Psychotic symptoms from MDPV can include hearing voices, visual hallucinations, urges to harm oneself, severe anxiety, mania, grandiosity, paranoid delusions, confusion, increased aggression, and irritability.

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.
