|Summary sheet: 25C-NBOMe|
|Common names||25C-NBOMe, Cimbi-36, 25C|
|Routes of Administration|
25C-NBOMe (also known as Cimbi-36, 2C-C-NBOMe, and "N-Bomb", although this term is used broadly to refer to the entire 25x-NBOMe family) is a novel synthetic psychedelic substance of the phenethylamine chemical class. It produces an array of visually-dominant and stimulating psychedelic effects when administered.
The name 25C-NBOMe, which short-hand for 2C-C-NBOMe, is a derivative of the phenethylamine psychedelic 2C-C. It was discovered in 2003 by Ralf Heim at the Free University of Berlin, and subsequently investigated by a team at Purdue University led by David Nichols. It has been studied in its 11C radiolabelled form as a potential ligand for mapping the distribution of 5-HT2A receptors in the brain, using positron emission tomography (PET).
It is worth noting that compounds of the NBOMe family are not orally active and should be administered sublingually by placing and holding it into one's mouth and allowing it to absorb over a period of 15-25 minutes. 25C-NBOMe can also be vaporized and inhaled; this is known to cause significantly more rapid and powerful effects and a shorter duration. However, this route of administration is highly advised against due to the difficulties of measuring and handling substances that are both active in the microgram range as well as having a low therapeutic index.
This substance had no history of human use before being sold online as a designer drug in 2010. Extremely little is known about the pharmacological properties, metabolism, and toxicity of 25C-NBOMe in humans, and it has been associated with many deaths and hospitalizations. Along with its highly sensitive dose-response and unpredictable effects, many reports also suggest that this substance may be overly difficult to use safely. Therefore it is highly advised to approach this poorly understood psychedelic substance with the proper amount of precaution and harm reduction practices if choosing to use it.

25C-NBOMe or 2C-C-NBOMe is a serotonergic N-benzyl derivative of the substituted phenethylamine psychedelic known as 2C-C. 25C-NBOMe is a substituted phenethylamine with methoxy groups CH3O- attached to carbons R2 and R5 as well as a chlorine atom attached to carbon R4. It differs from 2C-C structurally through a substitution on the amine (NH2) with a 2-methoxybenzyl (BOMe) group as shown in the image to the right. 25C-NBOMe shares this 2-methoxybenzyl substitution with other chemicals of the NBOMe family. This NBOMe addition contains a methoxy ether CH3O- bound to a benzene ring at R2.
25C-NBOMe has efficacy at the 5-HT2A receptor where it acts as a potent partial agonist. However, the role of these interactions and how they result in the psychedelic experience continues to remain elusive.
In comparison to 2C-C, the addition of an NBOMe group to the structure results in a sixteen fold increase in potency, allowing even the most extreme of dosages to fit in liquid form onto tabs and blotter paper, which people often mistake for LSD. In comparison to LSD however it is only a third of the potency.
The effects listed below are based upon the subjective effect index and personal experiences of PsychonautWiki 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.
- 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.
- Mouth 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 one's blotter paper contains LSD or one of the NBOMe series.
- Temperature regulation suppression
- Spontaneous physical 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 bodily lightness - 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 felt gravity - Compared to classic tryptamines, this effect is considerably less intense than what is commonly experienced with DMT and Psilocin.
- Nausea - As the user 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.
- Abnormal heartbeat
- Increased heart rate
- Increased blood pressure
- Muscle contractions
- Muscle cramps
- Muscle tension
- Gustatory hallucinations
- Appetite suppression
- Stomach cramps
- Dry mouth
- Difficulty urinating or Frequent urination
- Restless legs
- Pupil dilation
- 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 appearance and unrealistic/cartoon-like in style.
- After images
- Colour shifting
- Environmental cubism
- Scenery slicing
- Symmetrical texture repetition
The visual geometry that is present throughout this trip is often described as very similar in appearance to that of LSD. They can be comprehensively described as algorithmic in geometric style, intricate in complexity, fine and zoomed out in detail, fast and smooth in motion, structured in shape, colourful in scheme, glossy in colour, sharp around the edges and mostly rounded across their corners. In comparison to other more commonly used psychedelics, they can be described as significantly more intricate than the visual geometry found within 2C-I and most of the 2C-x family in general as well as completely on par with LSD, Psilocin and DMT at appropriately high dosages, which seem lower in proportion to the accompanying physical effects when compared to that of 25I-NBOMe.
In terms of their behaviour, 25C-NBOMe’s geometry leads onto Level 8A visual geometry with Level 8B remaining so far unconfirmed within this substance. They also seem to consistently build up in visual intensity when the tripper stares at a central point. This eventually envelopes the visual field and creates the sensation that the tripper has broken through into a continuously shifting geometric landscape or structure with a vast sense of immersive physical size attributed to it.
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.
These effects include:
- 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 a personal, religious, spiritual, science-fiction, fantasy, surreal, nonsensical or 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.
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.
The most prominent of these cognitive effects generally include:
- Analysis enhancement - This effect is generally only present at low doses.
- Thought acceleration and Thought deceleration - Although one of 25C-NBOME's effects is thought acceleration, the opposite may occur at higher doses.
- Conceptual thinking - This effect is considered to be very mild compared to traditional psychedlics.
- Anxiety & Paranoia - This effect seems to occur more readily than other psychedelics, perhaps due to its very prominent stimulating properties
- Feelings of impending doom - This is generally only experienced during the comedown period or if one has taken a large amount of the substance.
- Empathy, affection, 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)
- Language suppression
- Memory suppression
- Novelty enhancement
- Immersion enhancement
- Emotion enhancement
- Increased sense of humor
- Increased music appreciation
- Personal bias suppression
- Increased libido
- Time distortion
- Dosage independent intensity - While the reasons for this are not understood, many reports suggest that this substance can produce unexpectedly strong or weak effects even when taken at the seemingly same dose in an unpredictable manner. This may contribute to the relative risk it is poses compared to most other psychedelics.
- 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.
- While they are occasionally reported, the transpersonal effects produced by this substance seem to be significantly less consistent and reproducible than other psychedelics, which perhaps corresponds with the mild alterations in the cognitive alterations it produces.
Anecdotal reports which describe the effects of this compound within our experience index include:

- Experience:2mg 25C-NBOMe - Experimental trip to test personal limits of NBOMes

Toxicity and harm potential
25C-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. 25C-NBOMe overdoses have also been linked to multi-organ failure.
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 substances.
Tolerance and addiction potential
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 are built almost immediately after ingestion. After that, it takes about 7 days for the tolerance to be reduced to half and 14 days to be back at baseline (in the absence of further consumption). 25C-NBOMe presents cross-tolerance with all psychedelics, meaning that after the consumption of 25C-NBOMe all psychedelics will have a reduced effect.

Although many substances are safe on their own, they can become dangerous and even life-threatening when combined with other substances. The list below contains some common potentially dangerous combinations, but may not include all of them. Certain combinations may be relatively harmless in low doses of each but can still increase the risk of unpredictable injury or death. Independent research should always be done to ensure that a combination of two or more substances is safe before consumption.
- Tramadol - Tramadol lowers the seizure threshold and psychedelics may act as triggers for seizures, particularly in those who are predisposed to them.
- Stimulants - Stimulants affect many parts of the brain. Combined with psychedelics, stimulation can turn into uncontrollable anxiety, panic, thought loops and paranoia. This interaction may cause elevated risk of psychosis.
- Lithium - Lithium is often used as treatment for bipolar disorder. It may possibly cause elevated risk of seizures and psychosis due to its glutaminergic and GABAergic effects.
