25C-NBOMe Stats & Data
COc1ccccc1CNCCc1cc(OC)c(Cl)cc1OCFJFPOGCVVLUYAQ-UHFFFAOYSA-NHistory & Culture
25C-NBOMe was discovered in 2003 by Ralf Heim at the Free University of Berlin. The compound was subsequently investigated by a research team at Purdue University led by David Nichols, and was first formally described in the scientific literature by Anders Ettrup and colleagues in 2010. Research interest in 25C-NBOMe has centered on its potential applications in neuroimaging. Scientists have studied its carbon-11 radiolabelled form as a ligand for mapping the distribution of serotonin 5-HT2A receptors in the brain using positron emission tomography (PET). The compound had virtually no history of recreational human use prior to 2010, when it first emerged on the online research chemical market. Its exceptional potency—approximately sixteen times that of its parent compound 2C-C—allows effective doses to fit onto blotter paper, similar to LSD. This characteristic has led to instances where 25C-NBOMe has been found on blotter mimics sold as LSD, contributing to safety concerns and prompting regulatory responses across numerous jurisdictions beginning in 2011.
Subjective Effects
Physical
The physical effects of 25C-NBOMe can be broken down into several components which progressively intensify proportional to dosage.
- Stimulation and Sedation: In terms of its effects on the subject's physical energy levels, 25C-NBOMe is considered to be energetic and well as sedating, leaving the subject in a state of equilibrium between being stationary and moving. The physical stimulation manifested by this substance can be described as similar to 2C-B, and is commonly experienced as simultaneously easygoing and physically difficult, sometimes presenting overstimulation which results in bodily shakes and teeth grinding. The levels of stimulation can be considered less intense than 25I-NBOMe and the sedation can be considered slightly less intense than other psychedelics such as Psilocin and 2C-C.
- Sublingual numbing: Assuming the substance has been taken sublingually, the very first physical effect which a person will notice immediately after sublingual absorption is a strong, unpleasant metallic chemical taste. This is accompanied by a very obvious feeling of general numbness of the tongue and mouth which can stay for up to an hour after the blotter paper has been consumed. This is the key difference when it comes to determining whether your blotter paper contains LSD or one of the NBOMe series.
- Temperature regulation loss
- Spontaneous tactile sensations: The body high itself can be described as a generally mild, all-encompassing, soft but euphoric tingling sensation. This tingling sensation is also accompanied by spontaneous rushes of euphoria that become longer and more drawn out proportional to the dosage consumed.
- Perception of decreased weight: In terms of the body's perceived weight, this substance consistently leaves people feeling extremely light, often to the point of total weightlessness.
- Tactile hallucinations
- Changes in gravity: Compared to classic tryptamines, this effect is considerably less intense than what is commonly experienced with DMT and Psilocin.
- Nausea: As the tripper begins to come up, nausea is not uncommon and can sometimes result in initial vomiting, but passes once this has either happened or the trip begins to fully set in. In comparison to other psychedelics such as psilocin, LSD, 2C-E and 2C-I, this could actually be very considered very mild in its intensity.
- Vasoconstriction
- Increased heart rate
- Pupil dilation
- Wakefulness
- Increased blood pressure
Cognitive
The cognitive effects of 25C-NBOMe are described by many as remarkably light and underwhelming in comparison to more traditional psychedelics. It is not uncommon for people to report feeling that their thought stream has maintained general normality in its specific style throughout low to moderate dosages. At high dosages, however, mild to overwhelming cognitive alterations become present; this dosage seems to be lower in proportion to physical effects when compared to 25I-NBOMe.
- Analysis enhancement: This component is consistently manifested only in the context of a non-social setting in which the user is alone and is introspection dominant.
- Empathy, love and sociability enhancement: The entactogenic effects range from mild to powerful, but are inconsistently manifested. Entactogenic effects for people who try this substance usually become prominent in the presence of others. These feelings of increased sociability, love and empathy do not seem to be quite as strong or profound as those found within other entactogens (such as MDMA, 2C-B and AMT)
- Thought acceleration
- Time distortion
- Immersion enhancement
- Novelty enhancement
- Conceptual thinking
- Thought connectivity
- Current mind state enhancement
- Personal bias suppression
- Memory suppression
- Ego death
Sensory
- Enhancements
- Distortions
- Hallucinations
- Drifting: (Melting, flowing, breathing and morphing) - In comparison to other psychedelics this effect can be described as highly detailed, slow and smooth in motion, static in their appearance and unrealistic/cartoon-like in style.

25C-NBOMe presents a full and complete array of possible visual enhancements.
- Visual acuity enhancement
- Colour enhancement
- Pattern recognition enhancement
25C-NBOMe is capable of producing a full range of hallucinatory states within the level 1 - 3 range extremely consistently. However, level 4 - 5 hallucinatory breakthroughs are reported but very uncommon and inconsistent in comparison to other more commonly used psychedelics such as psilocin, 2C-E and DMT. This can be considered as on par with and identical in behaviour to that of LSD and 25I-NBOMe.
- Transformations
- Internal hallucinations: (Autonomous entities; settings, sceneries, and landscapes; alterations in perspective and scenarios and plots) These are more common within dark environments and can be described as internal in their manifestation, lucid in believability, interactive in style and almost exclusively of religious, spiritual, mystical or a transcendental nature in their overall theme.
- External hallucinations: (Autonomous entities; settings, sceneries, and landscapes; alterations in perspective and scenarios and plots). These are often manifesting as rapidly moving, interactive solid and typically asymmetrical matter or physical beings reflecting imagined concepts. They are more common in bright environments and can be described as external in their manifestation, equally lucid and delirious in believability, interactive in style, autonomous in interaction, and almost exclusively alien, mystical, or a transcendental nature in their overall theme.

Toxicity
PsychonautWiki25C-NBOMe is a relatively new substance, and little is known about its pharmacological risks or its interaction with other substances. The LD50 has not yet been determined although it can be fatal at heavy dosages. It is advised that due to 25C-NBOMe's extreme potency it should not be insufflated (snorted) as this method of administration has been attributed to several fatal overdoses due to improper dosing. It is strongly recommended that one use harm reduction practices when using this substance.
Addiction & dependence
25C-NBOMe 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 25C-NBOMe is built almost immediately after ingestion.

Also reported in combinations. In the 53 25C-NBOMe reports where another drug was taken too, 7 (13.2%) mention hospital, emergency services or an overdose, 2 (3.8%) a seizure and 5 (9.4%) psychosis. In the 60 single-substance reports: 15.0%, 5.0% and 0.0%. These are not in the figures above: they cannot be put down to 25C-NBOMe alone, and a mention is not always something that happened to the writer.
