25I-NBOMe (also known as 2C-I-NBOMe, NBOMe-2C-I, Cimbi-5, Smiles, and one of many drugs referred to as N-Bomb) is a novel psychedelic substance of the phenethylamine chemical class that produces an array of visually-dominant and stimulating psychedelic effects when administered.

The name 25I-NBOMe, which short-hand for 2C-I-NBOMe, is a derivative of the phenethylamine psychedelic 2C-I. It was first synthesized and documented in 2003 by Ralf Heim at the Free University of Berlin.[3] It was further researched by a team at Purdue University led by David Nichols.[4] 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).[5][6]

It is worth noting that compounds of the NBOMe family (any of which could be referred to as "N-Bomb", especially 25I-NBOMe and 25N-NBOMe) 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.

Extremely little is known about the pharmacological properties, metabolism, and toxicity of 25I-NBOMe in humans. It had no history of human use before being sold online as a designer drug in 2010.[citation needed]. It has been associated with many deaths and hospitalizations. Anecdotal reports suggest that this substance may be difficult to use safely due to its highly sensitive dose-response and unpredictable effects.

Chemistry

25I-NBOMe or 2C-I-NBOMe is a serotonergic N-benzyl derivative of the substituted phenethylamine psychedelic known as 2C-I. 25I-NBOMe is a substituted phenethylamine with methoxy groups CH3O- attached to carbons R2 and R5 as well as an iodine atom attached to carbon R4. It differs from 2C-I structurally through a substitution on the amine (NH2) with a 2-methoxybenzyl (BOMe) group. 25I-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.

Pharmacology

Further information: Serotonergic psychedelic

25I-NBOMe has efficacy at the 5-HT2A receptor where it acts as a Full agonist.[5] However, the role of these interactions and how they result in the psychedelic experience continues to remain elusive.

Among psychedelics, this compound is considered to be pharmacologically unique in terms of the high potency, affinity, and selectivity with which it binds to the 5-HT2a receptor.[5] Contrary to popular belief, it is not a "full agonist"[citation needed], although questions have been raised about how the effects it produces differ from other 5-HT2a partial agonists, which include the range of traditional psychedelics.

The Ki values of the following targets were greater than 500 Ki: 5-HT1A, D3, H2, 5-HT1D, α1A adrenergic, δ opioid, serotonin reuptake transporter, 5-HT5A, 5-HT1B, D2, 5-HT7, D1, 5-HT3, 5-HT1E, D5, muscarinic M1-M5, H3, and the dopamine reuptake transporter.[7]

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 ☠.

Auditory effects
 

Multi-sensory effects
 

    • 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.[citation needed] 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.

Toxicity and harm potential

Further information: Research chemicals § Toxicity and harm potential, and Responsible use § Hallucinogens

Short-term as well as long-term damage of NBOMes have been occasionally tied to serious physical and mental problems on seemingly random people, including memory and speech difficulties, heart problems, HPPD and in some cases Anxiety and PTSD, from particularly difficult experiences.

25I-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 is potentially fatal at heavy dosages.[1] PsychonautWiki advises that due to 25I-NBOMe's extreme potency it should not be insufflated as this method of administration appears to have led to several deaths in the past year.

This substance came to media attention in early 2012 after a cluster of seven non-fatal overdoses with the drug were reported in or around Richmond, Virginia.[8][9] As of May 2013, 25I-NBOMe has reportedly led to five overdose deaths in the United States.[10] In June 2012, two teens in Grand Forks, North Dakota and East Grand Forks, Minnesota fatally overdosed on a substance that was allegedly 25I-NBOMe, resulting in lengthy sentences for two of the parties involved and a Federal indictment against the Texas-based online vendor.[11]

A 21-year-old man from Little Rock, Arkansas died in October 2012 after taking a liquid drop of the drug nasally at a music festival. He was reported to have consumed caffeinated alcoholic beverages for "several hours" beforehand. It is unclear what other drugs he may have consumed, as autopsies usually do not test for the presence of research chemicals.[12]

A man in Australia died from injuries sustained by running into trees and power poles while intoxicated by 25I-NBOMe.[13]

A Brazilian 16-year-old died from overdose in April 2016.[citation needed]

The addition of 5-HTP can greatly increase the effects of 25i-NBOME and should be avoided.[citation needed]

It is strongly recommended that one use harm reduction practices when using this substance.

Tolerance and addiction potential

25I-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 25I-NBOMe is built almost immediately after ingestion. After that, it takes about 1 week for the tolerance to be reduced to half and 2 weeks to be back at baseline (in the absence of further consumption). 25I-NBOMe presents cross-tolerance with all psychedelics, meaning that after the consumption of 25I-NBOMe all psychedelics will have a reduced effect.

Overdose

Due to the very high potency and seemingly unpredictable effects the margin between a normal and an overdose of NBOMe compounds is extremely small when compared to many other substances. The exact toxic dose is unclear since it seems to depend a lot on personal physiology, rather than predominantly dose. However, various anecdotal reports suggest that dangerous side effects begin to appear when exceeding 1000 μg and it possibly becoming lethal for the more sensitive people at roughly 2000 μg. Reports of other people surviving much higher doses, sometimes even without any major side effects have been documented as well.

There is also the uncertainty of dosage on blotter paper since it is rather difficult to lay such an exact dosage. Insufflating, vaporizing or drinking tinctures of this substance is highly discouraged because of this and has been tied to many documented deaths[1][14][2]. One study found that 25I‐NBOMe and 25C‐NBOMe blotter papers contained 'hotspots' with higher quantities of the drug, implying an inherent risk of overdosing.[15]

The overdose effects of NBOMes are typically a dangerously high heart rate, blood pressure, hyperthermia and significant vasoconstriction[16][17] also accompanied by confusion, delusions, panic attacks, aggressive behavior, numbness or pain, amnesia and often seizures. The risks in an overdose include anything from organ failure to cardiac arrest and death[citation needed]. There are also multiple reports of people lethally injuring themselves or falling to death[18][19]. Benzodiazepines or antipsychotics can help with the psychological effects during an overdose although medical attention should always be called in even a possible overdose of 25I-NBOMe.

Dangerous interactions

 

This dangerous interactions section is a stub.

As such, it may contain incomplete or invalid information. You can help by expanding upon or correcting it.

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. Due to the highly unpredictable nature of the NBOMe series, it is generally advised to avoid mixing them with other psychoactive substances.

  • 2C-T-X - The 2C-T-X phenethylamines can be unpredictable in their interactions and the NBOMes are known to be unpredictable even alone. As a result, this combination should be avoided.
  • 5-MeO-xxt - The 5-MeO tryptamines can be unpredictable in their interactions and the NBOMes are known to be unpredictable even alone. As a result, this combination should be avoided.
  • Amphetamines - Amphetamines and NBOMes both provide considerable stimulation. When combined they can result in tachycardia, hypertension, vasoconstriction and, in extreme cases, heart failure. The anxiogenic and focusing effects of stimulants are also not good in combination with psychedelics as they can lead to unpleasant thought loops. NBOMes are known to cause seizures and stimulants can increase this risk.
  • aMT
  • Caffeine - Caffeine can bring out the natural stimulation from psychedelic drugs to make it uncomfortable. High doses can cause anxiety which is hard to handle while tripping.
  • Cannabis - Cannabis has an unexpectedly strong and unpredictable synergy with the effects of psychedelics. 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 over intake.
  • Cocaine - Cocaine and NBOMes both provide considerable stimulation. When combined they can result in severe vasoconstriction, tachycardia, hypertension, and in extreme cases heart failure.
  • DOx
  • DXM
  • Lithium - Lithium is commonly prescribed in the treatment of [https://en.wikipedia.org/wiki/Bipolar_disorder 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.
  • MAOIs - MAO-B inhibitors can increase the potency and duration of phenethylamines unpredictably.
  • MDMA
  • MXE - As an NMDA antagonist, MXE potentiates NBOMes which can be unpleasantly intense.
  • Tramadol - Tramadol is well known to lower seizure threshold and NBOMes have also shown a tendency to cause severe seizures
