Methoxphenidine (MXP) or 1-[1-(2-methoxyphenyl)-2-phenylethyl]piperidine is a hallucinogenic dissociative compound of the piperdine chemical class. It has similar effects to that of the arylcyclohexylamine and morphinan classes of dissociatives.

It induces a state referred to as “dissociative anesthesia” and is used as a recreational drug. Very little is known about this substance but it has recently become freely available through online research chemical vendors where it is being sold as a designer drug and marketed as a replacement for MXE despite many users reporting it as qualitatively different in its effects and closer to that of DXM. It has yet to be studied within humans in any formal context.

In terms of its chemistry, MXP is classed as a piperdine drug. The piperdine molecule in MXP is attached to a benzene group via two carbon atoms on one side and a methoxybenzene molecule attached to one carbon on the other side. It is usually produced in its freebase form, which is insoluble in water. When consumed orally, the molecule is converted to the hydrochloride salt in the stomach. The HCl salt is reported to raise blood pressure, and peak effects are felt around 2 hours in, whereas the citrate salt has been observed to peak at around 30 minutes with less blood pressure concern. This is the same principal as DXM which is more potent in its citrate salt.

As for its pharmacology, MXP has antagonistic action on NMDA receptors, which leads to anaesthetic and dissociative effects. Although it has not been formally studied, the feelings of physical and emotional euphoria which many users report suggests that it may also have action as a dopamine reuptake inhibitor.

The MXP experience contains a complex and wide array of effects which based on the predefined potential subjective effects index found here, I will now begin to breakdown and describe.

Physical effects:

The subjective physical effects of MXP are most similar to that of DXM than any other commonly used dissociative. They can be broken down into seven components all of which progressively intensify proportional to dosage. These are described below and generally include:

• Disconnection from tactile input - this results in typical states of progressive physical disconnection but is far more consciously controllable than that of other dissociatives. This allows one to choose how much of their body they are currently aware of and connected to simply by directing their focus towards it even throughout higher states of disconnection and out of body experiences.
• Spontaneous tactile sensations - the MXP body high is a soft, pleasurable vibrating sensation. It can be felt all over the body and progressively intensifies throughout the onset before dissipating once the peak has been reached.
• Suppression of touch - this partially to entirely suppresses one’s own sense of touch, creating feelings of numbness within the extremities. It is responsible for the anaesthetic properties of this substance.
• Physical autonomy
• Loss of motor control - a loss of gross and fine motor control alongside of balance and coordination is prevalent within MXP and becomes especially strong at higher dosages. This means that one should be sitting down before the onset unless they are experienced in case of falling over and injuring oneself.
• Euphoria - this results in feelings of physical euphoria which range between mild pleasure to powerful all encompassing bliss.
• Decreased bodily weight - this creates the sensation that the body is floating and has become entirely weightless. This effect is strangely stimulating and encourages physical activities at low - moderate dosages by making the body feel light and effortless to move.
• Dizziness

Cognitive effects:

The head space of MXP is often described as particularly clear headed even at heavy dosages. It is far more controllable, less disorientating and confusing at dosages of equal subjective intensity to that of MXE, DXM and Ketamine. The cognitive effects of MXP can be broken down into 6 separate subcomponents which are listed and described below:

• Disconnection from consciousness
• Acceleration of thought
• Ego suppression, loss and death
• Time distortion - feelings of time dilation and more time having passed than it actually has are common at moderate to strong dosages.
• Euphoria
• Conceptual thinking

Visual effects:

The visual effects of MXP are unique in comparison to other dissociatives as they do not include open eye visual suppression, geometry or distortions but still remain very powerful at appropriate dosages. The present effects progressively intensify according to dosage and commonly include:

• Disconnection from visual input - this eventually results in the MXP’s equivalent of the famous “K-hole” or more specifically, holes, spaces and voids alongside of level 1 - 4 structures. In comparison to other substances, this effect is unique however as it is far more consciously controllable than that of other dissociatives. It allows one to choose how disconnected they currently are by simply directing their focus towards the external environment even throughout higher states of disconnection and out of body experiences.
• Internal hallucinations - these hallucinatory states can be described as dream like in nature while often containing imagery, landscapes, plots, settings, autonomous entity contact and scenarios. They are more common within dark environments and can be described as internal in their manifestation, lucid in believability, mostly unimmersive in style and extremely controllable in their content in a way which allows one to choose what they wish to see.

Auditory effects:

The auditory effects of MXP are common in their occurrence but unlike other more commonly used dissociatives, they are unlikely to suppress or distort auditory input and exhibit a small range of effects which exclusively includes:

• Enhancements

Afterglow:

The afterglow is a feeling that occurs within the 24 hours after the trip itself. It is long lasting and as equally enjoyable as the trip itself to many people. It can be be described in terms of its physical sensation as one of euphoria, rejuvenation, relaxation and a light bounciness. In terms of its mental thought processes however, it can be described as a complete loss of anxiety, feelings of contentedness and an extremely high appreciation for music which dissipates within a day or so after the experience.

Health effects, addiction potential and tolerance:

The toxicity and long term health effects of recreational MXP use does not seem to have been studied in any scientific context and the exact toxic dosage is unknown. This is because MXP is a research chemical with very little history of human usage. Anecdotal evidence from people who have tried MXP within the community suggests that there are no negative health effects attributed to simply trying this drug at low to moderate doses or using it very sparingly (but nothing can be completely guaranteed).

There is a very strong tolerance build up with MXP which results in the need to consume increasingly large doses in order to achieve the same level of effects. This should reset to baseline after 1 - 2 weeks. There may well be some addictive potential but this is still unknown.

Tolerance may be mitigated via preparing the citrate salt by mixing the chemical with citric acid or lemon juice, which will aid in absorption and increase effects.

Legal Issues:

MXP is currently a legal grey area world wide and freely available through the use of online research chemical vendors. This does not mean that you are guaranteed to be immune from legal prosecution should you be found in possession of this substance as it is likely to vary from country to country.

Conclusion:

This new dissociative is an extremely novel, capable and interesting compound. The potential negative effects are currently unknown so tread carefully and start with light dosages if you are so inclined.

2C-I or 2,5-dimethoxy-4-iodophenethylamine is a psychedelic phenethylamine of the 2C-x family. It was first synthesized by Alexander Shulgin. It was described in Shulgin’s 1991 book PiHKAL: A Chemical Love Story. The drug is used recreationally for its psychedelic and entactogenic effects and is sometimes confused for the analog 25I-NBOMe. 2C-I is commonly sold in its hydrochloride salt form, which is a fluffy, sparkling, white powder, which can sometimes be pressed into tablet form. 2C-I has been explored as a potential stimulant nootropic in doses between 1-8mg.

In terms of its chemistry, 2C-I is a substituted phenethylamine with methoxy groups attached carbons R2 and R5 as well as an iodine molecule attached to carbon R4. It is thought to have efficacy at the 5-HT2A receptor as a partial agonist.

The 2C-I experience contains a complex and wide array of effects which based on the predefined potential subjective effects index found here, I will now begin to breakdown and describe.

Physical effects:

The physical effects of 2C-I can be broken down into five components all of which progressively intensify proportional to dosage. These are described below and generally include:

• Spontaneous tactile sensations - The body high of 2C-I is manifested as one of the most proportionally intense in comparison to almost all of the classical psychedelics. The sensation itself can be described as an intense and slightly uncomfortable energetic pins and needles sensation that constantly encompasses a person’s entire body. It is usually felt over every square inch of the skin but occasionally manifests itself in the form of a continuously shifting tingling sensation that travels up and down the body in spontaneous waves. Alongside of this, many users commonly report that the body high can be particularly uncomfortable and sometimes accompanied by dysphoric aches and urges to shift the position of one’s body and prolonged tensing of unusual combinations of muscle groups.
• Euphoria - Feelings of frequent but unpredictable rushes of warm physical euphoria are extremely common and very pleasurable. These move from the top of the head downwards before envoloping ones whole body.
• Stimulation - In terms of its effects on the physical energy levels of the tripper, 2C-I is usually considered to be very energetic and stimulating in a fashion that is quite comparable to that of MDMA although encouraged instead of forced.
• Increased bodily control
• Enhancement of touch
• Nausea - Mild to extreme nausea is consistently reported when consumed in moderate to high dosages and either passes once the tripper has vomited or gradually fades by itself as the peak sets in.
• Loss of temperature regulation
• Head aches - Some users report mild but uncomfortable head pressures which can occasionally intensify during the offset of the experience.

Cognitive effects:

The head space of 2C-I is described by many as one which is relatively normal in its thought processes even at moderate to high dosages. It is often said to lack insight when compared to that of 2C-E, 2C-B and LSD.
The total sum of these cognitive components regardless of the setting generally includes:

• Increased empathy, love and sociability - This component is consistently manifested only in the context of social settings in which one is within the company of others. These feelings of sociability, love and empathy are a little weaker and less sharp than those found on substances such as MDMA and 2C-B but still prove strong enough to provide long lasting therapeutic effects.
• Time distortion
• Feelings of fascination, importance and awe
• Sexual arousal
• Enhancement of current mind state
• Ego suppression, loss and death
• States of unity and interconnectedness

Visual effects:

Enhancements

2C-I presents a full and complete array of possible visual enhancements which generally includes:

• Increased visual acuity
• Enhancement of colour
• Enhanced pattern recognition

Distortions

2C-I presents a full and complete array of possible visual distortions which generally includes:

• Drifting (melting, flowing, breathing and morphing) - In comparison to other psychedelics, this effect can be described as simplistic and bland in detail, slow and smooth but sometimes jittery in motion, static in appearance and unrealistic/cartoon-like in style.
• Tracers
• Symmetrical texture repetition - In comparison to other psychedelics such as LSD and 2C-E this particular effect is bland and simplistic.
• Colour shifting
• Scenery slicing

Geometry

The visual geometry that is present throughout this trip can be described as more similar in appearance to that of LSD or 2C-B than that of 2C-E, psilocin, or ayahuasca although it is much more bland and less detailed. They can be comprehensively described as unstructured in their organization, algorithmic in geometric style, intricate in complexity, large in size, fast and smooth in motion, colourful in scheme, glossy in colour, both soft and sharp in their edges as well as equally rounded and angular in their corners. They seem high in algorithmic visuals such as fractals and at higher dosages are significantly more likely to result in states of Level 7A visual geometry over Level 7B.

Hallucinatory states

Like LSD, while 2C-I is capable of producing a full range of low and high level hallucinatory states, this is extremely rare and inconsistent at higher levels but common at lower and generally includes the following effects:

• External hallucinations - The experience of effects such as open eye transformations are common within 2C-I but not consistent.
• Internal hallucinations - Although 2C-I is technically capable producing of hallucinatory states in a fashion that is on par with psilocin or DMT in its vividness and intensity, in comparison, these effects are extremely rare and inconsistent. Whilst traditional psychedelics such as LSA, Ayahuasca and Mescaline will induce internal hallucinations near consistently at level 5 geometry and above, 2C-I hallucinations will not extend beyond imagery and higher dosages will for most will simply go straight into Level 7A visual geometry. This lack of consistently induced hallucinatory breakthroughs means that for most, 2C-I is simply not as deep of an experience as certain other psychedelics.

Auditory effects:

The auditory effects of 2C-I are common in their occurrence and exhibit a full range of effects which commonly include:

• Enhancements
• Distortions
• Hallucinations

Health effects, addiction potential and tolerance:

The toxicity and long term health effects of recreational 2C-I use does not seem to have been studied in any scientific context and the exact toxic dosage is unknown. This is because 2C-I is a research chemical with very little history of human usage. Anecdotal evidence from people who have tried 2C-I within the psychedelic community suggests that there are no negative health effects attributed to simply trying this drug at low to moderate doses or using it very sparingly (but nothing can be completely guaranteed).

There is a short period of tolerance after 2C-I use. Using 2C-I two days in a row is likely to lead to a diminished experience the second day. However, this effect is nearly non-existent when spaced 5-7 days apart.

Legal issues:

• European Union: In December 2003, the European Council issued a binding order compelling all EU member states to ban 2C-I within three months.
• Denmark: It is a controlled substance.
• Germany: It is a controlled substance.
• Greece: It is a controlled substance.
• Ireland: The drug is a controlled substance.
• Italy: It is a controlled substance.
• Netherlands: It is a controlled substance.
• Poland: It is a controlled substance.
• Sweden: Sveriges riksdag added 2C-I to schedule I (“substances, plant materials and fungi which normally do not have medical use”) as narcotics in Sweden as of March 16, 2004. 
• United Kingdom: It is controlled as a Class A substance.
• USA: As of July 9, 2012, in the United States, 2C-I is a Schedule I substance under the Synthetic Drug Abuse Prevention Act of 2012, making possession, distribution and manufacture illegal.

Conclusion:

2C-I is a worthwhile experience but is not as deep as other drugs of the same family. It is a substance which works better for some than others. For example, while many find it to be extremely uncomfortable others find it perfect for recreational use in public and social environments.
