THE

Studies

Recent research on 5-MeO-DMT, a psychedelic compound, has shown promising results in improving symptoms of depression, anxiety, PTSD, and substance use disorders. The substance has low addiction potential and may have psychotherapeutic effects.

​

A study conducted by Johns Hopkins researchers found that individuals with depression and anxiety experienced significant improvements in their symptoms after taking 5-MeO-DMT in a structured group setting. The intensity of the mystical experience from the substance was linked to these improvements.

​

In another study using animal models, researchers explored the behavioral effects of 5-MeO-DMT on brain regions associated with depression. They found that the substance, similar to psilocybin, reduced social vocalizations in mice and altered their vocalization patterns.

​

Additionally, the researchers used two-photon microscopy imaging to study the impact of 5-MeO-DMT on nerve cell structures called dendritic spines. They observed that a single dose of 5-MeO-DMT increased the number of dendritic spines, which are crucial for neural plasticity and cognitive functions like learning and memory. This increase persisted for a month after the dose.

​

These findings suggest that 5-MeO-DMT has potential therapeutic benefits for mental health conditions by promoting neural plasticity and altering behavioral responses. However, further research is needed to fully understand its mechanisms and long-term effects.

The study on 5-MeO-DMT found that the psychedelic dramatically reorganizes low-frequency brain activity, leading to disorganized, fleeting neural patterns rather than the coherent waves seen in typical brain states like sleep or anesthesia. Despite this disruption, the brain entered a more stable, low-dimensional state with fewer global shifts in activity. These findings offer new insights into how 5-MeO-DMT alters brain dynamics, providing a unique perspective compared to other psychedelics and suggesting potential therapeutic applications​.

5-MeO-DMT, distinct from classic psychedelics such as LSD, psilocybin, and mescaline, appears to primarily target a different subset of serotonin receptors, particularly the 5-HT1A receptor, rather than the 5-HT2A receptor, which is typically linked to the hallucinogenic effects of other psychedelics. While classical psychedelics are known for their activation of the 5-HT2A receptor, a crucial element for producing vivid sensory hallucinations and altered states of consciousness, 5-MeO-DMT diverges in its receptor interactions.

​

Studies suggest that 5-MeO-DMT’s effects—characterized by rapid onset, disorientation, and a sense of profound detachment from the environment—are more closely tied to the activation of 5-HT1A receptors.

 

This receptor subtype, associated with mood regulation and anxiolytic effects, points to a fundamentally different mechanism of action compared to the 5-HT2A pathway. When volunteers are pretreated with 5-HT2A blockers before taking substances like LSD, they report no detectable psychoactive effects. This highlights the critical role of 5-HT2A in classical psychedelic experiences. However, 5-MeO-DMT's unique, intense experiences seem less reliant on this pathway, possibly explaining its distinct, non-hallucinogenic effects.

​

Recent research published in Nature has advanced our understanding of this difference by investigating the dual activation of 5-HT1A and 5-HT2A receptors by 5-MeO-DMT. These findings indicate that the two receptor subtypes contribute in different ways to the drug’s effects, with 5-HT1A playing a more dominant role in shaping 5-MeO-DMT’s intense and disorienting experiences.
