4-Chloro-2,5-dimethoxyphenethylamine (commonly known as 2C-C) is a lesser-known psychedelic substance of the phenethylamine class that produces psychedelic effects when administered.[1] It is a member of the 2C-x family of psychedelic phenethylamines, all of which were derived from the systematic modification of the mescaline molecule.

2C-C was first synthesized by Alice C. Cheng and Neal Castagnoli Jr. in 1983 as an intermediate in a study evaluating the neurotoxicity of 6-hydroxydopamine analogs.[2] Its activity in humans was later investigated and documented by Alexander Shulgin in his book PiHKAL ("Phenethylamines I Have Known and Loved").

Many users report that the effects of 2C-C are gentler, more relaxed, and sedating than other closely related psychedelic phenethylamines such as 2C-B, 2C-I, and 2C-E. It is one of the least potent members of the 2C-x family, with muted visual effects and a relatively unaltered headspace.

Very little data exists about the pharmacological properties, metabolism, and toxicity of 2C-C, and its history of human use is limited. Today, it is used for recreational and therapeutic purposes. It is rarely sold on the streets and distributed online as a grey area research chemical.


Generic structure of a phenethylamine molecule

2C-C or 2,5-dimethoxy-4-chlorophenethylamine is a substituted phenethylamine featuring a phenyl ring bound to an amino (NH2) group through an ethyl chain. 2C-C contains methoxy functional groups CH3O- attached to carbons R2 and R5 as well as a chlorine atom attached to carbon R4 of the phenyl ring. 2C-C belongs to the 2C family of phenethylamines which contain methoxy groups on the 2 and 5 positions of the benzene ring.[1]


Further information: Serotonergic psychedelic

2C-C'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 is the subject of ongoing scientific investigation.

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 ☠.

Combinational effects

  • Cannabis - Cannabis majorly intensifies and extends both the sensory and cognitive effects of 2C-C. Extreme caution should be exercised with this combination as it can also elevate the anxiety, confusion and psychosis risk of cannabis.
  • Dissociatives - When combined with dissociatives, the geometry, euphoria, dissociation and hallucinatory effects are often greatly enhanced. Dissociative-induced holes, spaces, and voids while under the influence of 2C-C have significantly more vivid visuals than dissociatives alone. It also results in more intense internal hallucinations and corresponding confusion which can develop into delusions and psychosis.
  • Nitrous - Nitrous oxide is commonly used in combination with psychedelics. The two are known to possess powerful cross-synergistic effects, including the capacity to send the user directly into an "ego death" state. The speed and intensity with which this occurs is very rapid and the euphoria that can result often leads to the urge to compulsively redose.
  • MDMA - When combined with MDMA, the physical and cognitive effects of 2C-C become strongly amplified. The visual, physical and cognitive effects of 2C-C are also intensified with strong sensations of euphoric pleasure manifested through distinct body highs and headspaces, and uniquely colorful visuals. The synergy between these substances is unpredictable, and it is best to start with markedly lower dosages than one would take for both substances individually. This combination may increase the neurotoxic effects of MDMA based on its similarity to LSD, which has been found to increase MDMA neurotoxicity.[3]
  • Alcohol - Alcohol can increase the disinhibiting and euphoric effects of 2C-C which lends to its use in recreational settings. It can be used in light doses to "take the edge off" a trip as well as dull its psychedelic effects in a fashion somewhat similar to benzodiazepines. However, this is not typically recommended due to alcohol’s ability to cause dehydration and nausea and physical fatigue which can negatively affect a trip if taken in moderate to high dosages. Heavy drinking is strongly discouraged as it can easily lead to black outs and unpredictable behavior.
  • Benzodiazepines - Benzodiazepines can, depending on the dosage, slightly to completely reduce the intensity of the cognitive, physical and visual effects of a 2C-C trip. They are very efficient at stopping "bad trips" at the cost of amnesia and reduced trip intensity. Caution is advised when acquiring them for this purpose due to their very high abuse and addiction potential.
  • Psychedelics - When used in combination with other psychedelics, each substance's physical, cognitive and visual effects intensify and synergize strongly. The synergy between those substances is unpredictable, and for this reason generally not advised. If choosing to combine psychedelics, it is recommended to start with significantly lower dosages than one would take for either substance individually.

Toxicity and harm potential

The toxicity and long-term health effects of recreational 2C-C use do not appear to have been studied in any scientific context and the exact toxic dose is unknown. This is because 2C-C is a research chemical with a limited history of human use.

Anecdotal reports from those who have tried this compound suggest 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 (although nothing can be completely guaranteed). Independent research should always be conducted 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 substance.

Tolerance and addiction potential

Although no formal studies have been conducted, it is not unreasonable to assume that like psychedelics in general, 2C-C is not habit-forming and that the desire to use it can actually decrease with use.

Tolerance to the effects of 2C-C is not built almost immediately after ingestion. Similar to 2C-B there seems to be no apparent tolerance buildup if used repeatedly for a few days. 2C-C does however produce cross-tolerance with other serotonergic psychedelics, meaning that after the use of 2C-C 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.
