PMMA can cause serious side effects even at moderate doses, such as hyperthermia and serotonin syndrome, which can easily result in death or hospitalization.

As a result, it is strongly discouraged to use this substance. Please see this section for more details.

Interactions
Summary sheet: PMMA

PMMA (also known as para-Methoxymethamphetamine or 4-MMA) is a highly dangerous and toxic drug of the amphetamine class, which is closely related to PMA. Like PMA, it has extremely dangerous side effects, which can result in death. At lower dosages, its effects are somewhat different from PMA, with reduced tendency to cause severe hyperthermia and producing more entactogenic effects, although at higher dosages it does have the same risk as PMA. Its history of use is unknown, but it has appeared more frequently in the 2000s and 2010s. It is generally less potent than PMA. PMMA, along with PMA have very little recreational value and are considered as one of the most dangerous and toxic substances known. It is strongly recommended that these two drugs should be completely avoided.

Chemistry

PMMA (para-Methoxymethamphetamine or 4-MMA) is a molecule of the amphetamine class. 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 Rα. It contains a methoxy (OCH3) functional group bound to the R4 carbon of the phenyl ring, as well as a methyl substitution at RN. It is the methylated version of PMA and the 4-Methoxy analog of Methamphetamine.

Pharmacology

This pharmacology section is incomplete.

You can help by adding to it.

PMMA, like PMA most likely acts as a selective serotonin releasing agent (SSRA) with weak effects on dopamine and norepinephrine transporters. However, relative to MDMA, it is considerably less effective as a releaser of serotonin with properties more akin to a reuptake inhibitor in comparison. It evokes robust hyperthermia while producing only modest hyperactivity and serotonergic neurotoxicity, substantially lower than that caused by MDMA. Anecdotal reports suggest it is not particularly euphoric at all, perhaps even dysphoric in contrast. PMMA has also been shown to act as a potent, reversible inhibitor of the enzyme MAO-A with no significant effects on MAO-B, and the combination of this property and serotonin release is likely responsible for its high lethality potential. It is likely metabolized to PMA, just like methamphetamine is metabolized to amphetamine in the body.

It appears that PMMA elevates body temperatures dramatically; the cause of this property is suspected to be related to its ability to inhibit MAO-A and at the same time releasing large amounts of serotonin, effectively causing serotonin syndrome. It appears that PMMA activates the hypothalamus much more strongly than MDMA and other drugs like ephedrine, thereby causing rapid increases in body temperature (which is the major cause of death in PMMA mortalities).[citation needed]

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

Cognitive effects

Visual effects

At moderate to high dosages, PMMA is capable of producing typically mild or moderate visual distortions, which are usually more common and pronounced than with MDMA, but significantly less when compared with most psychedelics, such as 2C-B or LSD.

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.

PMMA and its relative PMA [[Toxicity::can be considered extremely toxic when compared to other substances such as Methamphetamine or MDMA ]]. [[Toxicity::Ingestion of PMMA has been associated with severe tachycardia (abnormally high heart rate), seizures, dehydration, hyperthermia, and death]]. PMMA has a relatively slow onset, causing many users to redose which causes excess toxicity.

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

  • Canada: PMMA is a Schedule I substance.
  • Germany: PMMA is an Anlage I controlled substance.
  • United States: PMMA is unscheduled, but can be considered an analog of PMA under the Federal Analog Act.
  • United Kingdom: PMMA is a Class A drug.
