Summary sheet: 3-MeO-PCE

It has recently become available on the online grey area research chemical market and has a similar effect profile to that of 3-MeO-PCP or PCP.

Chemistry

3-MeO-PCE, or N-Ethyl-1-(3-methoxyphenyl)cyclohexan-1-amine, is classed as an arylcyclohexylamine drug. Ayrlcyclohexylamine drugs are named for their structures which include a cyclohexane ring bound to an aromatic ring along with an amine group. 3-MeO-PCE contains a phenyl ring with a methoxy (CH₃-O-) substituent at R₃ bonded to a cyclohexane ring. Bound to the same carbon (R₁) of the cyclohexanone ring is an amino ethyl chain -NCH₂CH₃. 3-MeO-PCE, like MXE contains an amino ethyl chain rather than the amino methyl chain found in DCK and ketamine. 3-MeO-PCE is analogous to MXE, but lacks a R₂ substituted ketone. It is also homologous to 3-MeO-PCP buts lacks the additional carbons to complete a piperidine ring.

Pharmacology

Main article: NMDA receptor antagonist

3-MeO-PCE acts principally as an NMDA receptor antagonist. NMDA receptors allow for electrical signals to pass between neurons in the brain and spinal column; for the signals to pass, the receptor must be open. Dissociatives close the NMDA receptors by blocking them. This disconnection of neurons leads to loss of feeling, difficulty moving, and eventually an almost identical equivalent of the famous “k-hole.”

3-MeO-PCE has Ki values of 61 nM for the NMDA receptor, 115 nM for the serotonin transporter, 4519 nM for the σ1 receptor and 525 nM for the σ2 receptor.

Subjective effects

3-MeO-PCE can be said to share extremely similar properties to that of 3-MeO-PCP but with a considerably higher risk of inducing dangerous psychosis which may make it dangerous to use regardless of the setting.

It is significantly more stimulating and less sedating than other dissociatives such as ketamine or MXE. It's far more comfortable than O-PCE, MXP, Diphenidine and other noradrenaline reuptake-inhibiting dissociative compounds which suggests that it may have a higher affinity for dopamine or serotonin.

The effects listed below are based upon the subjective effects index and personal experiences of PsychonautWiki contributors. The listed effects will rarely (if ever) occur all at once, but heavier dosages will increase the chances and are more likely to induce a full range of effects.

Physical effects

• Motor control loss
• Perception of decreased weight
• Physical autonomy
• Physical euphoria - At lower to moderate dosages the sensation itself can be described as feelings of physical comfort, warmth and euphoria which spreads throughout the body. However, at heavier dosages this sensation becomes neutral or potentially uncomfortable in terms of its enjoyability.
• Spatial disorientation
• Spontaneous tactile sensations - The body high of this compound can be described in terms of its style variations as a motionless, constant, sharp, all-encompassing, euphoric general activation of nerve endings across the body. This feels half way between the same sensations induced by 3-MeO-PCP and O-PCE.
• Stimulation - This drug is extremely stimulating in comparison to other dissociatives such as ketamine, MXE, or DCK. The stimulation it presents is clean and comfortable in a manner which is far closer to that of 3-MeO-PCP than that of O-PCE.
• Tactile disconnection
• Tactile suppression
• Increased heart rate - an uncomfortably increased heart rate may become present at heavier dosages but is not noticeable at low to moderate dosages. It tends to become more prominent towards the offset of the trip.

Cognitive effects

• Amnesia
• Anxiety suppression
• Consciousness disconnection
• Compulsive redosing
• Conceptual thinking
• Creativity enhancement
• Déjà vu
• Depersonalization
• Derealization
• Disinhibition
• Dream potentiation
• Existential self-realization
• Euphoria
• Mania - This effect is seemingly more common on 3-MeO-PCE than other dissociatives (such as 3-Meo-PCP, ketamine or MXE). It commonly occurs during the offset of the trip particularly if one has been binging or consuming large amounts.
• Memory suppression
  • Ego death
• Immersion enhancement
• Increased music appreciation
• Information processing suppression
• Introspection
• Psychosis - This effect is seemingly more common on 3-MeO-PCE than other dissociatives (such as 3-Meo-PCP, ketamine or MXE). It commonly occurs during the offset of the trip particularly if one has been binging or consuming large amounts. Anecdotal evidence suggests that this compound is potentially the most psychotomimetic dissociative currently available on the research chemical market, even more so than 3-MeO-PCP.
• Time distortion
• Thought deceleration

Visual effects

• Color enhancement

Suppressions

• Visual disconnection - This eventually results in 3-MeO-PCE's equivalent of the famous "k-hole" or more specifically, holes, spaces and voids alongside of structures. However although it is possible to achieve, this may be significantly more dangerous than other dissociatives due to the accompanying psychosis.
• Double vision
• Frame rate suppression
• Pattern recognition suppression
• Visual acuity suppression

Distortions

• Perspective distortions
• Scenery slicing
• Visual drifting

Geometry

The visual geometry found within 3-MeO-PCE can be described as very dark and bland when compared to that of ketamine or DXM and often consists of many tiny interlocking and woven lines. It does not extend beyond level 4 and can be comprehensively described through its variations as simplistic in complexity, algorithmic in style, synthetic in feel, unstructured in organization, dimly lit in lighting, multicoloured in scheme, glossy in shading, soft in edges, small in size, slow in speed, smooth in motion, equal in rounded and angular corners, immersive in depth and consistent in intensity.

Hallucinatory states

• Internal hallucinations (autonomous entities; settings, sceneries, and landscapes; alterations in perspective and scenarios and plots)

Auditory effects

• Suppression and enhancement
• Distortions
• Hallucinations

Toxicity and harm potential

Main article: Research chemicals § Toxicity and harm potential

The toxicity and long-term health effects of recreational 3-MeO-PCE use do not seem to have been studied in any scientific context and the exact toxic dosage is unknown. This is because 3-MeO-PCE has very little history of human usage.

Psychosis

3-MeO-PCE has been reported to cause psychosis and mania at a significantly higher rate than other dissociatives such as ketamine, diphenidine, or MXE. There are a large number of experience reports online which describe states of "psychotic delirium, amnesia, mania, and other serious consequences" after abusing the drug.

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

• Users should avoid taking the drug multiple days in a row or becoming addicted to it as this increases the risk of severe adverse effects.
• The recommended dosage range should not be exceeded as high doses can trigger these effects as well.
• Users should start with extremely low doses and work their way up as slowly as possible. Volumetric liquid dosing should preferably be used due to the drug's potency; most standard milligram scales cannot accurately weigh out doses below 10-15mg.
• Compulsive redosing before one has fully sobered up is not recommended and can result in too high of a dose.

Due to the risk of psychosis, it is not recommended to combine this drug with other substances, especially stimulants, psychedelics, or other dissociatives like MXE. Independent research should always be done to ensure that a combination of two or more substances is safe before consumption.

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

Tolerance and addiction potential

The chronic use of 3-MeO-PCE can be considered highly addictive with a high potential for adverse side effects such as psychosis. In comparison to other dissociatives, 3-MeO-PCE has been reported to be more addictive than MXE, diphenidine, ephenidine, and ketamine. When addiction has developed, cravings and withdrawal effects may occur if a person suddenly stops their usage. There have been multiple reports across the internet of people becoming seriously addicted daily users of this substance so serious precautions and considerations should be taken before trying this substance.

Tolerance to many of the effects of 3-MeO-PCE 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). 3-MeO-PCE presents cross-tolerance with [[Cross-tolerance::all dissociatives]], meaning that after the consumption of 3-MeO-PCE, all dissociatives will have a reduced effect.

Urinary tract effects

In terms of its long-term health effects when used repeatedly and with excess for extended periods of time, 3-MeO-PCE seems to exhibit almost identical bladder and urinary tract problems to those found within ketamine, but to a lesser extent. This is because 3-MeO-PCE is far more potent than ketamine so significantly less of drug needs to be consumed. Symptoms of ketamine-induced cystitis can become extremely serious and can be described as:

• Urinary frequency - Urinary frequency is the need to empty the bladder every few minutes.
• Urinary urgency - This can be described as a sudden, compelling need to urinate.
• Urinary pressure - This is experienced as a constant sensation of fullness in the bladder that is unrelieved by urination.
• Pelvic and bladder pain - Pain can develop suddenly and severely, particularly as the bladder fills with urine.
• Hematuria - Hematuria is visible blood in the urine.
• Incontinence - This is the leakage of urine.

All of these, however, can easily be avoided by simply not using 3-MeO-PCE on a daily or even weekly basis and consciously limiting one's usage of the substance.

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.

• Psychedelics - This combination is not advised because 3-MeO-PCE has been reported to cause extreme psychological disturbances such as psychosis and mania at a significantly higher rate than other dissociatives.
• Stimulants - This combination is not advised because 3-MeO-PCE has been reported to cause extreme psychological disturbances such as psychosis and mania at a significantly higher rate than other dissociatives.
• Stimulants - Both stimulants and dissociatives carry the risk of adverse psychological reactions like anxiety, mania, delusions and psychosis and these risks are exacerbated when the two substances are combined.
• Depressants - Because both depress the respiratory system, this combination can result in an increased risk of suddenly falling unconscious, vomiting and choking to death from the resulting suffocation. If nausea or vomiting occurs, users should attempt to fall asleep in the recovery position or have a friend move them into it.
