|Summary sheet: 5F-AKB48|
|Common names||5F-AKB48, 5F-APINACA|
|Chemical class||Indazolecarboxamide / Adamantane|
|Routes of Administration|
Cannabinoids are commonly smoked or vaporized to achieve a quick onset of effects and rapid offset. 5F-AKB48 is orally active when dissolved in a lipid, which can increase the duration significantly. Like other cannabinoids, it is insoluble in water but dissolves in ethanol and lipids.
Unlike cannabis, the chronic abuse of synthetic cannabinoids has been associated with multiple serious injuries deaths and more dangerous side effects and toxicity in general. Therefore, it is strongly discouraged to take this substance for extended periods of time or in excessive doses.
5F-AKB48, or N-(adamantan-1-yl)-1-(5-fluoropentyl)-1H-indazole-3-carboxamide, is a synthetic indazolecarboxamide as it contains a substituted indazole group. This indazole moeity is substituted at R1 with a fluoropentyl chain, a substitution shared with 5F-PB-22. Additionally, the indazole is substituted at R3 with a carboxamide group. This carboxamide group is N-substituted at its terminal amine group with an adamantane group. This group consists of four fused cyclohexane rings in a unique structure called a diamondoid. 5F-AKB48 is an analog of STS-135 in which the core indole structure is substituted with an indazole base.
Although this substance has not been formally studied, from analysis of the structure, it is presumed that 5F-AKB48 has a similar binding profile to that of other cannabinoids and matches many of the in vivo properties of Δ9-THC. However, the role of these interactions and how they result in the cannabinoid high continues to remain elusive.
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 ☠.
- Spontaneous physical sensations - The "body high" of 5F-AKB48 can be described as a sharp, uncomfortable, all-encompassing, and electric tingling sensation that spreads over the body after initial ingestion. It maintains a consistent presence that quickly rises with the onset and hits its limit once the peak has been reached before immediately dissipating.
- Motor control loss - This substance causes a partial to moderate suppression of motor control which intensifies proportional to dose, but rarely results in a complete inability to walk and perform basic movements.
- Appetite enhancement - As with many other cannabinoids, 5F-AKB48 causes an increase in appetite, known colloquially as "the munchies" in popular American and United Kingdom culture. Clinical studies and survey data have found that cannabis increases food enjoyment and interest in food. This is thought to be due to the way in which endocannabinoids in the hypothalamus activate cannabinoid receptors that are responsible for maintaining food intake.
- Pain relief - Cannabinoids have been clinically demonstrated to provide pain relief via agonism of cannabinoid receptors CB1 and CB2, which extends to synthetic cannabinoid receptor agonists.
- Perception of bodily lightness
- Changes in gravity
- Dehydration- This is known colloquially as "cotton mouth" in popular American and United Kingdom culture.
- Anxiety - In comparison to other cannabinoids, this compound is particularly prone to inducing feelings of anxiety and it should therefore be avoided by people who are particularly prone to this state of mind.
- Emotion enhancement
- Thought connectivity
- Thought deceleration
- Conceptual thinking
- Analysis suppression
- Dream suppression
- Psychosis - The prolonged usage of synthetic cannabinoids may increase one's disposition to psychosis, particularly in vulnerable individuals with risk factors for psychotic illnesses (like a past or family history of schizophrenia).
- Increased music appreciation

Toxicity and harm potential
The toxicity and long-term health effects of recreational 5F-AKB48 use do not seem to have been studied in any scientific context and the exact toxic dosage is unknown. This is because 5F-AKB48 has very little history of human usage. Anecdotal evidence from people who have tried 5F-AKB48 within the community suggest that there do not seem to be any negative health effects attributed to simply trying this drug at low to moderate doses by itself and using it sparingly (but nothing can be completely guaranteed). Informal experiments have shown that overdose will cause physical discomfort including heart palpitations, vertigo and sedation at much lower than dangerous doses, usually causing the user to suffer large amounts of anxiety or to fall asleep.
It has often been recommended that those with severe pre-existing mental conditions should not ingest these substances due to the way they strongly increase one's current state of mind and emotions. Also, like THC, prolonged usage of synthetic cannabinoids including 5F-AKB48 may increase one's disposition to mental illness and psychosis, particularly in vulnerable individuals with risk factors for psychotic illnesses (like a past or family history of schizophrenia).
As synthetic cannabinoids are active in the milligram range (with below 5mg being a common dose), it is important to use proper precautions when dosing to avoid a negative experience.
It is strongly recommended that one use harm reduction practices when using this drug.
Tolerance and addiction potential
As with other synthetic cannabinoids, the chronic use of 5F-AKB48 can be considered moderately addictive with a high potential for abuse and is capable of causing psychological dependence among certain users. When addiction has developed, cravings and withdrawal effects may occur if a person suddenly stops their usage.
Tolerance to many of the effects of 5F-AKB48 develops with prolonged and repeated use. This results in users having to administer increasingly large doses to achieve the same effects. After that, it takes about 3 - 7 days for the tolerance to be reduced to half and 1 - 2 weeks to be back at baseline (in the absence of further consumption). 5F-AKB48 presents cross-tolerance with all cannabinoids, meaning that after the consumption of 5F-AKB48 all cannabinoids will have a reduced effect.
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.
