25B-NBOMe (also known as Cimbi-36, NBOMe-2C-B and 2C-B-NBOMe) is novel psychedelic substance of the phenethylamine class. It is a member of the 25x-NBOMe series, a recently discovered group of potent psychedelic compounds derived from the 2C-x family. The name 25B-NBOMe, which is short-hand for 2C-B-NBOMe, indicates it is a derivative of the phenethylamine psychedelic 2C-B.
25B-NBOMe was discovered in 2004 by Ralf Heim at the Free University of Berlin. [2] It acts as a potent partial agonist for the 5-HT2A receptor. [3] It has been used in clinical trials with an evaluation dose for safety consideration to humans of only 1 microgram. Such a dose was determined to be only 1/300th the dose expected to be hallucinogenic to humans and that recreational use would greatly exceed doses determined to be safe to humans. [3] This substance had no history of human use before being sold online as a designer drug in 2010. [ citation needed ]
Subjective effects include stimulation, open and closed-eye visuals, time distortion, euphoria, and ego loss. Anecdotal reports suggest 25B-NBOMe to be an active hallucinogen at a dose of as little as 250–500 µg, making it a similar potency to other phenethylamine derived hallucinogens such as Bromo-DragonFLY. [4] It is worth noting that compounds of the NBOMe class are not orally active and should therefore be taken sublingually by placing them into one’s mouth and allowing it to absorb over a period of 15-30 minutes.
Extremely little is known about the pharmacological properties, metabolism, and toxicity of 25B-NBOMe in humans. Numerous members of the 25x-NBOMe series have been associated with hospitalizations and deaths. 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 use harm reduction practices if using this substance.

Chemistry
25B-NBOMe or 2C-B-NBOMe is a serotonergic N-benzyl derivative of the substituted phenethylamine psychedelic known as 2C-B. 25B-NBOMe is a substituted phenethylamine with methoxy groups CH3O- attached to carbons R2 and R5 as well as a bromine atom attached to carbon R4. It differs from 2C-B structurally through a substitution on the amine (NH2) with a 2-methoxybenzyl (BOMe) group. 25B-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.
The compound has a density of 1.3 (±0.1) g/cm^3.
Pharmacology
25B-NBOMe has efficacy at the 5-HT2A receptor where it acts as a potent partial agonist. [5] [6] [7] [8] However, the role of these interactions and how they result in the psychedelic experience continues to remain elusive.
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 much more likely with increasing doses and may include addiction, serious injury, or death ☠.

Geometry
The visual geometry that is present throughout this trip is often described as 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.
In terms of their behaviour, 25B-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 user stares at a central point. This eventually envelops the visual field and creates the sensation that the user has broken through into a continuously shifting geometric landscape or structure with a vast sense of immersive physical size attributed to it.

Toxicity and harm potential
25B-NBOMe is a relatively new substance, and little is known about its pharmacological risks or its interaction with other substances. The lethal dosage has not yet been determined. One case has been reported on where 25B-NBOMe was identified as the cause of death for a 17-year-old boy. [9]
It is advised that due to 25B-NBOMe’s extreme potency it should not be insufflated as this method of administration is potentially fatal at heavy dosages. [10]
25B-NBOMe has been used in clinical trials with an evaluation dose for safety consideration to humans of only 1 microgram; Such a dose is 300× lower than the dose expected to be hallucinogenic to humans and it is expected that recreational use would greatly exceed doses determined to be safe to humans. [11]
It is strongly recommended that one use harm reduction practices when using this substance.
Tolerance and addiction potential
25B-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 25B-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). 25B-NBOMe presents cross-tolerance with all psychedelics, meaning that after the consumption of 25B-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.
Dangerous interactions
Disclaimer: Psychoactive substances that are reasonably safe to use on their own can suddenly become dangerous or even life-threatening when combined with other substances. The following list includes some known dangerous interactions (although it is not guaranteed to include all of them).
Independent research (e.g. Google, DuckDuckGo) should always be conducted 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.
Да ребята, присоединюсь. Ничего сильнее в жизни не пробовал. Время можно было остановить, перемотать, первый опыт общения с создателем (опыт бога), нахождение в 2 местах одновременно, животный страх и леденящий ужас в коктейле с пребыванием в раю и лучшем месте для разума и это всё одновременно. Миры и вселенные создаются и рушатся триллионы раз в мгновение. Повторить так и не решился. Если честно, после увиденного и умирать не страшно!
кто подскажет 3000mg n-boma на одного это много?
КМП США обращается к «торчкам» в своих рядах: «Ради Бога, прекратите «закидываться» кислотой!» [1]
Примечание 1. Это не мои формулировки, а журнала КМП США «Task&Purpose», в чем можно убедиться по ссылке [1].
Сообщение об этом было размещено на сайте DVIDS (Defense Visual Information Distribution Service)- официальном информационно- мультимедийном портале американского Министерства Обороны- 30 ноября 2020 г [2].
Сообщается, что данные результаты были получены в результате выборочных тестов; кандидаты для тестирования были отобраны произвольным образом. Результаты тестирования озвучил командир 2-й дивизии КМП США генерал- майор Фрэнсис Л. Донован, признав, что «во 2-й дивизии морской пехоты существует проблема употребления наркотиков» [1][2].
Здесь надо сказать, что военнослужащие в США и ранее неоднократно тестировались на наличие в организме следов наркотических препаратов, но данные тесты проводились только по запросам правоохранительных органов. Однако, «ряд инцидентов» с участием моряков и морпехов 2-й дивизии (2 MARDIV) заставил командование дивизии запустить широкомасштабное тестирование [1][2].
База ВВС F.E. Warren.
Но вернемся обратно к Корпусу морской пехоты. Из заявлений командира 2-й дивизии следует, что КМП США продолжает придерживаться принципа «нулевой терпимости» по отношению к употреблению наркотиков. Это заявление поддержал ряд других должностных лиц [2].
Примечание 2. Ну как тут не вспомнить программу MKUltra.
Как шутит «Task&Purpose», вероятно, майор придерживается принципа «если не можешь запретить, то возглавь», а некоторые особо ретивые военнослужащие просто буквально восприняли его советы по «расширению сознания и улучшению работы мозга» [1].
