'''2C-D''' ('''2,5-dimethoxy-4-methylphenethylamine''', also known as '''2C-M''') is a [[psychedelic]] drug of the [[2C-z]] family that is sometimes used as an [[entheogen]]. It was first synthesized in 1970 by a team from the Texas Research Institute of Mental Sciences,<ref>https://www.ncbi.nlm.nih.gov/pubmed/5412084</ref> and its activity was subsequently investigated in humans by [[Alexander Shulgin]]<ref>Alexander Shulgin - PIHKAL | http://www.erowid.org/library/books_online/pihkal/pihkal033.shtml</ref>. The full name of the chemical is '''2,5-dimethoxy-4-methylphenethylamine'''. In his book PiHKAL (Phenethylamines i Have Known And Loved), Shulgin lists the dosage range as being from 20 to 60 mg and many people recommend higher doses. Lower doses (generally 10 mg or less) of 2C-D have been explored as a potential nootropic, albeit with mixed results. 2C-D is generally taken orally, though may be insufflated (i.e. taken nasally). Insufflating tends to cause intense pain, however, and the dosage level is usually much lower, typically in the region of 1 to 15 mg.
Not much information is known about the toxicity of 2C-D, as no major studies have been conducted. According to Shulgin, the effects of 2C-D typically last for 4–6 hours. Shulgin himself referred to this substance as a “pharmacological tofu,” meaning that when mixed with other substances, it can extend or potentiate their effects without coloring the experience too much, in a manner similar to how tofu absorbs the flavors of sauces or spices it is cooked with. Some people have claimed 2C-D is relatively uninteresting on its own, but many other users have strongly disagreed with this assessment and believe that 2C-D is a true psychedelic in its own right.
'''2,5-Dimethoxy-4-methylphenethylamine''' (also known as '''2C-M''', '''LE-25''' and more commonly as '''2C-D''') is a synthetic [[Psychoactive class::psychedelic]] of the [[Chemical class::phenethylamine]] chemical class that produces short-lived [[psychedelic]] effects when [[routes of administration|administered]]. Its sensory and cognitive effects profile has been described as being the most similar to that of [[mescaline]] among members of the [[2C-x family]], albeit with a significantly shorter duration.
In modern times, it is used as a recreational drug and an [[entheogen]], rarely sold on the streets and almost exclusively obtained as a grey area research chemical through the use of online vendors. Therefore, it is relatively uncommon and has only a short history of human use.

Many anecdotal reports suggest that it is calmer, easier to handle and more comfortable on the body than other closely related [[psychedelic]] [[phenethylamines]]. While not especially visual or physically euphoric at common doses, it is reported to be very lucid, analytical and unimpaired in its headspace - a quality it retains even as the dose is increased.

Today, 2C-D is used both recreationally and as an [[entheogen]]. It is rarely sold on the streets and almost exclusively distributed as a gray area [[research chemical]] by online vendors.
==History and culture==
The synthesis of 2C-D was first published in 1970 by a team from the Texas Research Institute of Mental Sciences,<ref name="Ho1970"/>, but initial trials by [[Alexander Shulgin]] at sub-threshold doses were carried out in 1964. Further investigations at higher doses were carried out by Shulgin and his fellow researchers between 1974 and 1978.<ref name="Shulgin1976"/> The name '2C-D' derives from the chemical's structure - it is the 2-Carbon analogue of [[DOM]].
Shulgin notably referred to 2C-D as a “pharmacological tofu,” meaning it can extend or potentiate the effect of other substances without overly coloring the experience, in a manner similar to how tofu absorbs the flavors of sauces or spices it is cooked with.{{citation needed}} While some use this as evidence that 2C-D is relatively uninteresting as a psychedelic on its own, others strongly disagree with this assessment and hold that 2C-D is an unusually versatile and fully-fledged [[psychedelic]] in its own right.

However, the role of these interactions and how they result in the [[psychedelic]] experience continues to remain elusive due to lack of research and funding.
==Subjective effects==
The head space of 2C-D is described by many as being lucid, insightful and relatively normal in its thought processes even at moderate to high doses. The feeling of unaltered consciousness may be unsatisfying to users who want an intense experience because the head space is fairly normal, stable and therefore sometimes uninteresting to those who are new to hallucinogenic experiences.
==Subjective effects==
{{Preamble/SubjectiveEffects}}
The effects listed below are based upon the [[subjective effects index]] and personal experiences of [[PsychonautWiki]] [[Special:TopUsers|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.
{{effects/base
===Physical effects===
The physical effects of 2C-D can be broken down into several components which progressively intensify proportional to dosage. These are described below and generally include:
*'''[[Effect::Spontaneous tactile sensations]]''' - The "body high" of 2C-D can be described as a pleasurable, all-encompassing comfort sensation. This maintains a consistent presence that steadily rises with the onset and hits its limit once the peak has been reached.
|{{effects/physical|
*'''[[Effect::Sedation]]''' - In terms of its effects on the physical energy levels of the tripper, the 2C-D experience begins with mild sedation that increases as the trip progresses, and lacks the distinctive energetic feeling associated with most [[phenethylamines]].
*'''[[Effect::Stimulation]]''' - In terms of its effects on the physical energy levels of the user, the 2C-D experience begins with mild sedation that gives way to moderate stimulation as the experience progresses. It lacks the forceful energetic push associated with most psychedelic [[phenethylamines]].
*'''[[Effect::Nausea]]''' - Although nausea remains present, in comparison to other [[phenethylamines]] such as [[2C-E]], [[2C-I]] or [[2C-B]], this remains extremely mild and dissipates quickly even with higher dosages. It is a very kind and mild [[psychedelic]] for this reason.
*'''[[Effect::Spontaneous physical sensations]]''' - The "body high" of 2C-D can be described as a pleasurable, all-encompassing comfort sensation. This maintains a consistent presence that steadily rises with the onset and hits its limit once the peak has been reached.
*'''[[Effect::Bodily control enhancement]]''' and '''[[Motor control loss]]''' - Whilst at lower doses one may find that their bodily control is enhanced, at higher dosages it seems to become suppressed.
*'''[[Effect::Bodily control enhancement]]''' - Whilst at lower doses one may find that their bodily control is enhanced, at higher dosages it seems to become suppressed.
*'''[[Effect::Nausea]]''' - In comparison to other [[phenethylamines]] such as [[2C-E]], [[2C-I]] or [[2C-B]], any nausea produced by this substance tends to be very mild and dissipates quickly even with higher dosages.
*'''[[Effect::Pupil dilation]]'''

===Cognitive effects===
}}
The head space of 2C-D is described by many as one which is both insightful and relatively normal in its thought processes even at moderate to high dosages. The feeling of "unaltered consciousness" may be bothersome to trippers that are willing to experience events and concepts from a shifting point of view, since on 2C-D everything is fairly normal, stable and therefore rather uninteresting.
{{effects/visual|
Compared to other members of the 2C-x family like [[2C-B]], the visual effects of 2C-D have been noted for being understated until heavier doses are reached. After this point, a full spectrum of hallucinatory visual phenomena begin to appear.
The total sum of these cognitive components regardless of the setting generally includes:
*'''[[Effect::Analysis enhancement]]'''
*'''[[Effect::Thought acceleration]]'''
*'''[[Effect::Time distortion]]'''
*'''[[Effect::Novelty enhancement]]'''
*'''[[Effect::Conceptual thinking]]'''
*'''[[Effect::Thought connectivity]]'''
*'''[[Effect::Current mind state enhancement]]''' - The following three effects combine as a whole to provide an objective look into the current headspace of the tripper, often introspective and analytical.
*'''[[Effect::Personal bias suppression]]'''
*'''[[Effect::Memory suppression]]'''
**'''[[Effect::Ego death]]'''

*'''[[Effect::Drifting]]''' ''([[Drifting#Melting|melting]], [[Drifting#Flowing|flowing]], [[Drifting#Breathing|breathing]] and [[Drifting#morphing|morphing]])'' - In comparison to other psychedelics, this effect can be described as low in detail, slow and smooth in motion, static in appearance and realistic in style.
*'''[[Effect::Drifting]]''' ''([[Drifting#Melting|melting]], [[Drifting#Flowing|flowing]], [[Drifting#Breathing|breathing]] and [[Drifting#morphing|morphing]])'' - In comparison to other psychedelics, this effect can be described as highly detailed, slow and smooth in motion, static in appearance and realistic in style.

====[[effect::Geometry]]====
The visual geometry that is present throughout this trip can be described as more similar in appearance to that of [[DOM]] or [[25D-NBOMe]] than that of [[LSD]], [[2C-B]] or [[2C-I]]. They can be comprehensively described as structured in their organization, organic in style, intricate in complexity, large in size, slow and smooth in motion, colourful in scheme, bright in colour, blurred in its edges and equally rounded and angular in its corners. They give off a natural feel to them at higher dosages. Whilst the final level of 2C-D geometry 2C-D has yet to be formally confirmed, it seems more likely that it would result in states of [[Effect::8B Geometry|Level 8B]] visual geometry over [[8A Geometry|Level 8A]].

====Hallucinatory states====
====Hallucinatory states====
2C-D produces a full range of high level hallucinatory states in a fashion that is more consistent and reproducible than that of many other commonly used psychedelics. This holds particularly true in comparison to other substances within the [[phenethylamines|phenethylamine]] family. These effects include:
*'''[[Effect::Transformations]]'''
*'''[[Effect::Internal hallucination]]''' (''[[effect::autonomous entities]]''; ''[[effect::settings, sceneries, and landscapes]]''; ''[[effect::perspective hallucinations]]'' and ''[[effect::scenarios and plots]]'') - In comparison to other psychedelics such as [[LSD]], 2C-D is low in hallucinations embedded within visual geometry. However, when it does occur this particular effect commonly contains hallucinations with scenarios, settings, concepts and autonomous entity contact. They are more common within dark environments and can be described as internal in their manifestation, lucid in believability, and interactive in style.
*'''[[Effect::External hallucination]]''' (''[[effect::settings, sceneries, and landscapes]]''; ''[[effect::perspective hallucinations]]'' and ''[[effect::scenarios and plots]]'') - 2C-D is capable of external hallucinations embedded within visual geometry. This particular effect commonly contains hallucinations with scenarios, settings, concepts and autonomous entity contact. They can be described as external in their manifestation, lucid in believability, and fixed in style.

*'''[[Effect::Internal hallucinations]]''' (''[[effect::autonomous entities]]''; ''[[effect::settings, sceneries, and landscapes]]''; ''[[effect::alterations in perspective]]'' and ''[[effect::scenarios and plots]]'') - In comparison to other psychedelics such as [[LSD]], 2C-D is high in hallucinations embedded within visual geometry. This particular effect commonly contains hallucinations with scenarios, settings, concepts and autonomous entity contact.

===Auditory effects===
}}
The auditory effects of 2C-D are common in their occurrence and exhibit a full range of effects which commonly include:
*'''[[Effect::Synaesthesia]]''' - In its fullest manifestation, this is a very rare and non-reproducible effect. Increasing the dosage can increase the likelihood of this occurring, but seems to only be a prominent part of the experience among those who are already predisposed to synaesthetic states.

===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:
{{further|Research chemicals#Toxicity and harm potential|Responsible use #Hallucinogens}}
The toxicity and long-term health effects of recreational 2C-D use do not seem to have been studied in any scientific context and the exact [[Toxicity::toxic dose is unknown]]. This is because 2C-D is a [[research chemical]] with very little history of human usage.
===Lethal dosage===
Anecdotal evidence from those within the community who have tried 2C-D suggests that there are no negative health effects attributed to simply trying the substance by itself at low to moderate doses and using it very sparingly (but nothing can be completely guaranteed). [https://www.google.com Independent research] should always be done to ensure that a combination of two or more substances is safe before consumption.
The toxicity and long-term health effects of recreational 2C-D use do not seem to have been studied in any scientific context and the median lethal dose (LD50) is unknown. This is because 2C-D is a research chemical with very little history of human usage. Anecdotal evidence from those who have used 2C-D would suggest that there are little to no immediate or short-term negative health effects attributed to the consumption of the drug up to 50mgs. The validity of these statements, however, cannot be confirmed.
It is strongly recommended that one use [[responsible drug use|harm reduction practices]] when using this substance.
===Tolerance and addiction potential===
===Tolerance and addiction potential===
The addictive potential of 2C-D has not yet been formally studied, but anecdotal evidence would suggest that 2C-D is not physically addictive.
2C-D is [[Addiction potential::not habit-forming]] and the desire to use it can actually decrease with use. It is most often self-regulating.
Tolerance to the effects of 2C-D is built [[Time to full tolerance::almost immediately after ingestion]]. After that, it takes about [[Time to half tolerance::3 days]] for the tolerance to be reduced to half and [[Time to zero tolerance::7 days]] to be back at baseline (in the absence of further consumption). 2C-D presents cross-tolerance with [[Cross-tolerance::all [[psychedelic]]s]], meaning that after the consumption of 2C-D all psychedelics will have a reduced effect.
Many users describe a self-regulating quality and commonly report a tolerance build up when using the drug consecutively many days in a row. A build up in tolerance may lead to weakened effects and a diminished experience, however, this effect is nearly non-existent when consumption periods are spaced 5-7 days apart.

WARNING: Always start with lower doses due to differences between individual body weight, tolerance, metabolism, and personal sensitivity. See responsible use section.

2,5-Dimethoxy-4-methylphenethylamine (also known as 2C-M, LE-25 and more commonly as 2C-D) is a synthetic psychedelic of the phenethylamine chemical class that produces short-lived psychedelic effects when administered. Its sensory and cognitive effects profile has been described as being the most similar to that of mescaline among members of the 2C-x family, albeit with a significantly shorter duration.
The synthesis of 2C-D was first published in 1970 by a team from the Texas Research Institute of Mental Sciences.[1] Initial trials by Alexander Shulgin at sub-threshold doses in humans were carried out in 1964.[2]
Many anecdotal reports suggest that it is calmer, easier to handle and more comfortable on the body than other closely related psychedelicphenethylamines. While not especially visual or physically euphoric at common doses, it is reported to be very lucid, analytical and unimpaired in its headspace - a quality it retains even as the dose is increased.
Lower doses of 2C-D (generally 10 mg or less) have been explored for its use as a potential nootropic, albeit with mixed results.[3]
Today, 2C-D is used both recreationally and as an entheogen. It is rarely sold on the streets and almost exclusively distributed as a gray area research chemical by online vendors.
The synthesis of 2C-D was first published in 1970 by a team from the Texas Research Institute of Mental Sciences,[1], but initial trials by Alexander Shulgin at sub-threshold doses were carried out in 1964. Further investigations at higher doses were carried out by Shulgin and his fellow researchers between 1974 and 1978.[2] The name '2C-D' derives from the chemical's structure - it is the 2-Carbon analogue of DOM.
Shulgin notably referred to 2C-D as a “pharmacological tofu,” meaning it can extend or potentiate the effect of other substances without overly coloring the experience, in a manner similar to how tofu absorbs the flavors of sauces or spices it is cooked with.[citation needed] While some use this as evidence that 2C-D is relatively uninteresting as a psychedelic on its own, others strongly disagree with this assessment and hold that 2C-D is an unusually versatile and fully-fledged psychedelic in its own right.
Despite showing promise as a very functional psychostimulant[4][5] with successful studies investigating the use in psychotherapy in Germany,[6] 2C-D has not found widespread use. This has been argued to be due to the previously limited diversity of substances on the market - a consumer dynamic which has changed significantly with the advent of the internet - allowing a broader freedom of choice for explorers of psychedelic phenethylamines.[7] Of these, it tends to be substantially harder to find and notably more expensive by weight.[citation needed]
Chemistry
Generic structure of a phenethylamine molecule
2C-D, or 2,5-dimethoxy-4-methylphenethylamine, is a substituted phenethylamine featuring a phenyl ring bound to an amino (NH2) group through an ethyl chain. 2C-D contains methoxy functional groups CH3O- attached to carbons R2 and R5 as well as a methyl group attached to carbon R4 of the phenyl ring.
2C-D belongs to the 2C family of phenethylamines which contain methoxy groups on the 2 and 5 positions of the benzene ring.
2C-D's psychedelic effects are believed to come from its efficacy at the 5-HT2A receptor as a partial agonist. However, the role of these interactions and how they result in the psychedelic experience continues to remain elusive.
Subjective effects
The head space of 2C-D is described by many as being lucid, insightful and relatively normal in its thought processes even at moderate to high doses. The feeling of unaltered consciousness may be unsatisfying to users who want an intense experience because the head space is fairly normal, stable and therefore sometimes uninteresting to those who are new to hallucinogenic experiences.
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 PsychonautWikicontributors. 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
Stimulation - In terms of its effects on the physical energy levels of the user, the 2C-D experience begins with mild sedation that gives way to moderate stimulation as the experience progresses. It lacks the forceful energetic push associated with most psychedelic phenethylamines.
Spontaneous physical sensations - The "body high" of 2C-D can be described as a pleasurable, all-encompassing comfort sensation. This maintains a consistent presence that steadily rises with the onset and hits its limit once the peak has been reached.
Bodily control enhancement - Whilst at lower doses one may find that their bodily control is enhanced, at higher dosages it seems to become suppressed.
Nausea - In comparison to other phenethylamines such as 2C-E, 2C-I or 2C-B, any nausea produced by this substance tends to be very mild and dissipates quickly even with higher dosages.
Compared to other members of the 2C-x family like 2C-B, the visual effects of 2C-D have been noted for being understated until heavier doses are reached. After this point, a full spectrum of hallucinatory visual phenomena begin to appear.
Drifting(melting, flowing, breathing and morphing) - In comparison to other psychedelics, this effect can be described as low in detail, slow and smooth in motion, static in appearance and realistic in style.
The visual geometry of 2C-D be described as more similar in appearance to that of DOM or 25D-NBOMe than that of LSD, 2C-B or 2C-I. It can be comprehensively described as structured in its organization, organic in style, intricate in complexity, large in style, slow and smooth in motion, colorful in scheme, bright in color, blurred in its edges and equally rounded and angular in its corners. It gives off a natural feel at higher dosages. While the final level of 2C-D geometry has yet to be formally confirmed, it seems more likely that it would result in states of level 8B visual geometry over level 8A.
Internal hallucination (autonomous entities; settings, sceneries, and landscapes; perspective hallucinations and scenarios and plots) - In comparison to other psychedelics such as LSD, 2C-D is low in hallucinations embedded within visual geometry. However, when it does occur this particular effect commonly contains hallucinations with scenarios, settings, concepts and autonomous entity contact. They are more common within dark environments and can be described as internal in their manifestation, lucid in believability, and interactive in style.
External hallucination (settings, sceneries, and landscapes; perspective hallucinations and scenarios and plots) - 2C-D is capable of external hallucinations embedded within visual geometry. This particular effect commonly contains hallucinations with scenarios, settings, concepts and autonomous entity contact. They can be described as external in their manifestation, lucid in believability, and fixed in style.
Synaesthesia - In its fullest manifestation, this is a very rare and non-reproducible effect. Increasing the dosage can increase the likelihood of this occurring, but seems to only be a prominent part of the experience among those who are already predisposed to synaesthetic states.
There are currently no anecdotal reports which describe the effects of this compound within our experience index. Additional experience reports can be found here:
The toxicity and long-term health effects of recreational 2C-D use do not seem to have been studied in any scientific context and the exact toxic dose is unknown. This is because 2C-D is a research chemical with very little history of human usage.
Anecdotal evidence from those within the community who have tried 2C-D suggests that there are no negative health effects attributed to simply trying the substance by itself at low to moderate doses and using it very sparingly (but nothing can be completely guaranteed). Independent research should always be done to ensure that a combination of two or more substances is safe before consumption.
2C-D is not habit-forming and the desire to use it can actually decrease with use. It is most often self-regulating.
Tolerance to the effects of 2C-D is built almost immediately after ingestion. After that, it takes about 3 days for the tolerance to be reduced to half and 7 days to be back at baseline (in the absence of further consumption). 2C-D presents cross-tolerance with [[Cross-tolerance::all psychedelics]], meaning that after the consumption of 2C-D all psychedelics will have a reduced effect.
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.
[[Wikipedia:Lithium_(medication)|DangerousInteraction::Lithium]] - Lithium is commonly prescribed for the treatment of bipolar disorder. There is a large body of anecdotal evidence that suggests taking it with psychedelics significantly increases the risk of psychosis and seizures. As a result, this combination is strictly discouraged.
"[[UncertainInteraction" contains a listed "[" character as part of the property label and has therefore been classified as invalid.]] - Cannabis may have an unexpectedly strong and unpredictable synergy with the effects of 2C-D. Caution is advised with this combination as it can significantly increase the risk of adverse psychological reactions like anxiety, paranoia, panic attacks, and psychosis. Users are advised to start off with only a fraction of their normal cannabis dose and take long breaks between hits to avoid unintentional overdose.
"[[UnsafeInteraction" contains a listed "[" character as part of the property label and has therefore been classified as invalid.]] - Tramadol is well-documented to lower the seizure threshold[8] and psychedelics may act to trigger seizures in susceptible individuals.[citation needed]
