Psychedelic Research Chemicals or RC Chems are new synthetic substances which are structurally similar to the original drug, while being functional analogs. Data on their effects limited due as they’re fairly new and do not have a lot of human consumption history.

Psychedelics are substances (natural or laboratory made) which cause profound changes in a one’s perceptions of reality. While under the influence of hallucinogens, users might hallcuniate visually and auditorily.

Disclaimer: Psychedelic drugs offer some of the most powerful and intense psychological experiences. Additionally these substances are illegal in many places. We understand that even though these substances are illegal, their use occurs frequently. We do not condone breaking of the law. By providing accurate information about these substances, we encourage the user to make responsible decisions and practice harm reduction.

Auditory Effects

Psychological Effects

The cognitive effects of 3C-E are described as primarily stimulating and slightly confusing especially at higher dosages. The total sum of these cognitive components regardless of the setting generally includes:

Pharmacological Effects

3C-E’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.

Physical Effects

Sensory Effects

  • 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 only to be a prominent part of the experience among those who are already predisposed to synaesthetic states.

Subjective Effects

Disclaimer: The effects listed below are cited from the Subjective Effect Index (SEI), which relies on assorted anecdotal reports and the personal experiences of PsychonautWiki contributors. As a result, they should be taken with a healthy amount of skepticism. It is worth noting that these effects will not necessarily occur in a consistent or reliable manner, although higher doses (common+) are more likely to induce the full spectrum of reported effects. Likewise, adverse effects become much more likely on higher doses and may include serious injury or death.

Visual Effects

The visuals of 3C-E are generally not that apparent and consist more so of distortions than colors and drifting.




The visual geometry that is present throughout this trip can be described as more similar in appearance to that of DOC or mescaline than that of 2C-B, psilocin or LSD. It can be comprehensively described through its variations as intricate in complexity, abstract in form, synthetic in feel, structured in organization, brightly lit, multicolored in scheme, glossy in shading, sharp in edges, large in size, fast in speed, smooth in motion, equally rounded and angular in its corners, non-immersive in-depth and consistent in intensity.

Hallucinatory states

3C-E and other substituted amphetamines produce 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 phenethylamine family. These effects include:
