2C-B (4-bromo-2,5-dimethoxyphenethylamine) is a psychedelic phenethylamine of the 2C-x family; it was first synthesized by Alexander Shulgin in 1974.
This substance first saw use among the psychiatric community as an aid during therapy. It was considered one of the best drugs for this purpose because of its short duration, relative absence of side effects, and comparably mild nature.
Like many 2c-x substances, this drug is a highly dose sensitive psychedelic known for its entactogenic effects, bright visuals, and intense body load. This substance is often described by users as feeling half way between LSD and MDMA. Many reports suggest that while 2C-B’s entactogenic effects are less pronounced than MDMA, the visual effects are described as more pronounced and colourful.
The 2C-B experience contains a complex and wide array of psychedelic effects which I will now begin to breakdown and describe…
Physical effects:
The body high of 2C-B is not necessarily one of the most intense, but one of the most complex compared to other psychedelics, sharing components of MDMA, 2C-E, and LSD. This is first characterized by an intense soft warm glow that grows over the body and is capable of becoming extremely physically euphoric, this is most similar to MDMA and is consistently manifested throughout the experience. This is contrasted by an intensely pleasurable yet sharp, cold electric tingling sensation which moves up and down the body, this is most similar to LSD and is also consistently manifested throughout the trip. The final physical effect noticed throughout the experience is an intense and slightly uncomfortable, energetic pins and needles sensation that manifests itself in the form of a continuously shifting tingling sensation that travels up and down the body in spontaneous waves, this is most similar to 2C-E and is not entirely consistent throughout the trip.
In terms of its effects on the physical energy levels of the tripper 2C-B is usually considered to be very energetic and stimulating in a fashion that is quite comparable to that of MDMA.
A commonly felt physical component of the 2C-B trip is the way in which it heightens and enhances sexual arousal. When experienced, this sensation is not overwhelming or out of control but simply remains something that the tripper is constantly aware of. If sexual activities of any kind are engaged in, they are found to be immensely more pleasurable beyond anything that could be possible sober, with orgasm becoming difficult to reach but completely possible to obtain. When obtained the orgasm itself is capable of temporarily increasing the effects of the drug, this is most commonly experienced as visual effects dramatically increasing in a short yet powerful burst.
Bodily enhancements,
2C-B presents a full and complete array of bodily enhancements which generally includes,
- Enhanced tactile sensations
- Increased bodily awareness
- Increased muscle control
Cognitive effects:
The head space of 2C-B is described by many as one which is both insightful and relatively normal in its thought processes even at moderate to high dosages. This manifests itself as two different styles of head space that depend entirely on the setting. For example, when taken with others these effects manifest themselves as very strong entactogenic effects, when taken alone however psychedelic introspection is present. These feelings of sociability, love and empathy are a little weaker and less sharp than those found on substances such as MDMA but still prove stronger and more consistent than other psychedelics of any class, this is capable of providing long lasting therapeutic effects.
The total sum of these cognitive components regardless of the setting generally includes,
- Entactogenic effects (increased empathy and sociability)
- Sexual arousal
- Acceleration of thought
- Enhancement of current mindstate
- Feelings of fascination, importance and awe
- Introspection
- Suppression of cultural filter
- Conceptual thinking
- Ego suppression, loss and death
- Time distortion
Visual effects:
The visual effects experienced with 2C-B are commonly reported to manifest themselves in waves of increasing intensity and can be broken down into the following categories…
Enhancements,
2C-B presents a full and complete array of possible visual enhancements which generally includes,
- Increased visual acuity
- Enhancement of colours
- Enhanced pattern recognition
Distortions,
As for visual distortions and alterations, effects experienced are detailed below:
- Visual 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.
- Tracers
- After images
- Texture repetition
- Colour shifting
- Scenery slicing
Geometry,
The visual geometry that is present throughout this trip can be described as more similar in appearance to that of LSD than that of 2C-E, psilocin, or ayahuasca. They can be comprehensively described as unstructured in their organization, algorithmic in geometric style, intricate in complexity, large in size, fast and smooth in motion, colourful in scheme, glossy in colour, sharp in their edges and angular in their corners. They seem high in algorithmic visuals such as fractals and at higher dosages are significantly more likely to result in states of Level 7A visual geometry over Level 7B.
Hallucinatory states,
Like LSD, while 2C-B is capable of producing a full range of low and high level hallucinatory states, this is extremely rare and inconsistent at higher levels but common at lower.
- Transformations
- Imagery
- Hallucinations - While most traditional psychedelics such as LSA, Ayahuasca and Mescaline will induce hallucinations near consistently at level 5 geometry and above, 2C-B will for most simply go straight into Level 7A visual geometry.
Auditory effects:
The auditory effects of 2C-B are more common than some psychedelics in their occurrence and are capable of producing a full range of effects which commonly includes,
- enhancements
- distortions
- hallucinations
Physical health effects, potential addiction and tolerance:
There is no current data for the lethal dosage of 2C-B, but it is thought to be extremely high. Alexander shulgin reported in his book PIHKAL that an accidental dosage of 100mg resulted in no physical or psychological damage.
Since the invention of this substance in 1974, not a single person has yet to accidentally or deliberately experience a fatal overdose with this substance. This suggests that 2C-B is very safe but please keep in mind that clinical studies assessing its safety have not been performed in any scientific context.
In terms of its tolerance, 2C-B can be redosed repeatedly with little to no loss in the strength of its subjective effects. This means that is theoretically possible to become addicted to it but thanks to its psychedelic properties users experience a powerful self regulating quality to this substance.

Conclusion:
The main bulk of the 2C-B subjective effects breakdown for this particular article was not written by myself but the Encyclopedia Psychonautica admin known as Cocoanatta. I have tried 2C-B on two separate occasions and can confirm that the descriptions are indeed accurate.
As for the substance itself, 2C-B is an incredibly fun and therapeutically beneficial substance, this makes it extremely useful for both recreational and introspective purposes. It is in my opinion, the most suitable psychedelic for a beginner in existence due to its clear, euphoric headspace and proportionally mild visual effects in comparison to that of LSD or mushrooms.
LSA, broken down and described

Onset : 30- 180 min
Duration : 4 - 10 hours
Normal After Effects : 2 - 24 hours
LSA, also known as Ergine, d-lysergic acid amide and d-lysergamide, is an alkaloid of the ergoline family that occurs in various species of vines, the morning glory flower and some species of fungi. It is the dominant alkaloid found in the seeds of several varieties of morning glories in concentrations of approximately 10 µg per seed, as well as Hawaiian baby woodrose seeds, at a concentration of around 0.13% of dry weight. It has structural similarity’s to LSD, putting it in the lysergamide family of psychedelics.
A traditional use of morning glory seeds by Mexican Native Americans was first described by Richard Schultes in 1941 in a short report documenting their use going back to Aztec times. Further research was published in 1960, when Don Thomes MacDougall reported that the seeds of morning glory flowers were used as sacraments by certain Zapotecs, sometimes in conjunction with the seeds of Rivea corymbosa, another species of morning glory which has a similar chemical composition, containing lysergol instead of LSA.
The LSA experience contains a complex and wide array of psychedelic effects which I will now begin to breakdown and describe…
Physical effects:
The body high of LSA can be described as a mild yet pleasurable, soft tingling sensation. This is largely noticed in high doses and is accompanied by strong waves of euphoria which are usually manifested spontaneously at different unpredictable points throughout the trip but can also maintain a consistent presence, in either case however they steadily rise with the onset and hit their limit once the peak has been reached.
In terms of its effects on the physical energy levels of the tripper, LSA tends to be sedating however it can be setting dependent. For example, when taken in settings with large amounts of stimulus or during physically strenuous activities such as walking, running, climbing or dancing it is fully capable of becoming stimulating and energetic. In contrast however, when taken in calm environments such as darkened rooms with comfortable seating it is consistently relaxing, peaceful and quite sedating.
Cognitive effects:
The head space of LSA is described by many as extremely relaxing yet lucid and clear headed in its style when compared to other commonly used psychedelics such as LSD or Psilocin. Although the head space is primarily sedating, this is accompanied by fast paced bursts of thought which is complemented by a powerful enhancement of the ability to visualize concepts. This ability eventually becomes so drawn out proportional to dosage that it leads to full blown hallucinatory states that are entirely lucid and for the most part controllable.
LSA contains a large number of psychedelic cognitive effects. The most prominent of these typical effects include,
- Increased connectivity of thought
- Introspection
- Acceleration of thought
- Enhancement of current mind state
- Feelings of fascination and awe
- Conceptual thinking
- Ego suppression, loss and death
- Time distortion
- Communication with the subconscious
- Deja-vu
Visual effects:
The visual effects of LSA are mostly present when large doses have been consumed.
Enhancements,
LSA presents a full and complete array of possible visual enhancements which generally includes,
- Increased visual acuity
- Enhancement of colours
- Enhanced pattern recognition
Distortions,
As for visual distortions and alterations,these are significantly more simplistic from that of open eye distortions found with other psychedelics. Effects experienced are detailed below,
- Visual drifting (Melting, Flowing, Breathing and morphing) - In comparison to other psychedelics this effect can be described as mild but highly detailed yet cartoon like in appearance. They are fast yet smooth in motion and fleeting in their permanence. This is an inconsistently manifested effect with some never reporting such distortions.
- Colour shifting
Geometry,
The visual geometry that is present throughout this trip can be described as more similar in appearance to that of 4-AcO-DMT, Ayahuasca and 2C-E than LSD or 2C-B. They can be comprehensively described as structured in their organization, organic in geometric style, intricate in complexity, zoomed out and small in size, fast and smooth in motion, colourful in scheme, glossy in colour, blurred in their edges and rounded in their corners. They have a much more “natural” feel to them than LSD and at higher dosages are significantly more likely to result in states of Level 7B visual geometry over Level 7A.
Hallucinatory states,
LSA produces a full range of high level hallucinatory states in a fashion that is very consistent when taken in large doses. The effects of such states include,
- Transformations - these partially follow the content of the users current thought process
- Imagery - in comparison to other psychedelics such as LSD, LSA is extremely high in imagery embedded within the visual geometry.
- Hallucinatory states - unlike LSD, LSA consistently produces moderate to high level hallucinatory states in high doses. This particular effect can be compared to a lucid dream state and commonly contains hallucinations with plots, settings, autonomous entity contact and scenarios. They are more common within dark environments and can be described as internal in their manifestation, lucid in believability, interactive in style and almost exclusively religious, spiritual, mystical or transcendental nature in their overall theme. Compared to other hallucinatory states, LSA is more similar to ayahuasca than a dissociative or a deliriant.
Auditory effects:
The auditory effects of LSA are common in their occurrence and exhibit a full range of effects which commonly includes,
- enhancements
- distortions
- hallucinations
Natural sources:
Morning glory seeds,
The seeds of many species of morning glory contain lysergamide alkaloids such as the psychedelic known as LSA. The seeds are found in many gardening stores; however, it’s worth noting that the seeds from commercial sources are often coated in some form of pesticide or methylmercury which can result in extreme nausea if ingested. Seeds without these pesticides can be purchased cheaply online and are freely available through search engines such as google.
When using morning glory seeds the dosage for oral consumption is generally considered to be,
- Light : 50 - 100 seeds / 1.5 - 3 g
- Common : 100 - 250 seeds / 3 - 6 g
- Strong : 250 - 400 seeds / 6 - 10 g
- Heavy : 400 + seeds / 10 + g

Hawaiian baby woodrose seeds,
Hawaiian baby woodrose is a perennial climbing vine that is native to the Indian subcontinent and introduced to numerous areas worldwide, including Hawaii, Africa and the Caribbean. Hawaiian Baby Woodrose seeds may be consumed for their various lysergamide alkaloids, such as LSA. These seeds are found in many gardening stores; however, the seeds from commercial sources are often coated in some form of pesticide or methylmercury which can result in extreme nausea if ingested. Seeds without these pesticides can be purchased cheaply online and are freely available through search engines such as Google.
When using morning glory seeds the dosage for oral consumption is generally considered to be,
- Threshold : 1 - 4 seeds
- Light : 3 - 6 seeds
- Common : 5 - 8 seeds
- Strong : 7 - 12 seeds
- Heavy : 12 + seeds

Physical health effects, potential addiction and tolerance:
The toxic dosage of LSA is unknown as there has never been a single reported over dose. This suggests that LSA is perfectly safe to simply try on the odd occasion.
However, LSA should not be used on a frequent basis. When used repeatedly over a short period of time the vasoconstriction effects build up while the psychoactive effects get weaker. If you’re feeling sore legs, this is a sign of the vasoconstriction effects building up in your body. The legs feel sore because not enough blood is getting to the muscles. Your upper leg muscles are the largest, most energy eating muscles in your body, and they will feel sore if blood flow to them is lowered even a little bit. If you’ve taken HBWR seeds, morning glory seeds, pure LSA and are experiencing sore legs you need to hold off for a while. Let your body get back to baseline before using them again. This is more important with LSA (HBWR, morning glories, etc.). With LSA it can take up to 3 days of abstinence to get back to baseline.
It’s important to note that LSA is non-habit-forming and that the desire to use it can actually decrease with use, it is most often self-regulating. You also build an almost immediate tolerance to LSA after ingestion, preventing you from experiencing its full effects more often than every 4-7 days, unless you increase your dose significantly.
Legal issues:
- Consumption of LSA containing materials is prohibited under state legislation in most Australian states.
- LSA is not listed in Canada’s Controlled Drugs and Substances act and is therefore not illegal to possess. It is probably illegal to sell for human consumption as a drug, though the plants that contain it are not controlled in Canada.
- LSA is not legally classified as a drug, consumption or possession of LSA or LSA containing-materials is not prohibited.
- LSA is controlled in the Netherlands. This makes it illegal to possess, distribute, and produce without a license.
- Chemical LSA is controlled as a drug in New Zealand. The plants and seeds of morning glory species are legal to possess, cultivate, buy, and distribute. Seeds are reportedly sprayed and warnings included on the packets not to consume the seeds.
- Status of LSA as chemical unknown. LSA-containg plants appear to be uncontrolled in poland.
- Sweden is planning to control a number of chemicals as of May 1, 2007 including LSA, 2C-T-4, DXM, and DOI.
- LSA is a Class A substance within the United Kingdom, categorized as a precursor to LSD (Misuse of Drugs Act 1971).
Preparation methods:
LSA containing seeds can be prepared in a number of different ways. Click the links below for detailed step by step techniques,
- Extraction of LSA tincture - This extraction uses household chemicals such as naptha and ethanol to extract the LSA into a pure and nausea free liquid form. It is perfectly safe if performed correctly and can take between a few hours to several days depending on the desired potency.
- Nausea free LSA extraction with garlic - This extraction uses cold tap water and a refrigerator to extract the LSA from the seeds and into a glass of water. It uses garlic to minimize the nausea and takes at least 4 hours in total.
- LSA Adducts - This preparation method is not an extraction and merely theoretical but based around well reasoned chemistry and consistently themed anecdotal reports. It uses common household herbs such as Peppermint and cinnamon bark essential oil to convert LSA into other substances with radically altered subjective effects including LSH and CDLSA.
Reader submitted trip report:
In Conclusion:
The entirety of the LSA subjective effects breakdown for this particular article was not written by myself but the Encyclopedia Psychonautica admin known as Cocoanatta. I have tried LSA myself on numerous occasions and can confirm that this article is indeed accurate.
As for the substance itself, although LSA is well known across the psychedelic community, this substance has a pretty bad reputation for causing painful states of nausea, vomiting and vasioconstriction despite the fact that this can be greatly reduced depending on the method of preparation. Along side of this LSA is also perceived as a substance which only causes very mild visual and cognitive effects in comparison to other more “classical” psychedelics.
This assumption however is simply untrue. LSA goes just as deep as LSD, Mushrooms, Ayahuasca or any other psychedelic and you simply need to find the right dosage and extract it correctly. This makes LSA an excellent choice for any psychonaut, especially when considering how cost effective and widely available the natural plant sources are.
