As with DMT, CYB004 is a potent agonist of the serotonin 5-HT 2A receptor and produces psychedelic-like effects in animals. [ 1 ] [ 5 ] [ 3 ] However, CYB004, due to its deuteration, is more resistant to metabolism than DMT and shows a longer elimination half-life (by 2.5- to 2.9-fold) and slower clearance (by 38 to 55%) in animals.

[6] [7] [8] They can completely block or reduce the effects of hallucinogens [6] or they can simply provide anxiety relief and sedation. [3] Examples of trip killers, in the case of serotonergic psychedelics , include serotonin receptor antagonists , like antipsychotics and certain antidepressants , and benzodiazepines .
These two studies are some of the first large controlled studies measuring the effects of psychedelic therapy on depression and anxiety in cancer patients. [64] Across clinician-ratings and self-ratings, the psychedelic treatment produced statistically significant lowered anxiety and depression, with sustenance for at least 6 months.
[162] [164] [165] Similarly to DMT, 5-MeO-DMT is a biased agonist of the serotonin 5-HT 2A receptor, with minimal β-arrestin2 recruitment, and likewise has been associated with little tolerance to its hallucinogenic effects. [166] [140] As DMT has been shown to have slightly better efficacy (EC 50) at human serotonin 2C receptor than at the 2A ...
The drug does not produce hallucinogen-like stimulus generalization in animal drug discrimination tests and similarly does not produce the head-twitch response, an animal behavioral proxy of psychedelic-like effects. [1] [2] [4] [6] As such, it is not expected to be hallucinogenic in humans.
To date studies have explored the utility of psilocybin in a variety of diseases, including TRD, [14] [15] smoking addiction, [16] [17] and anxiety and depression in people with cancer diagnoses. [18] LSD is being tested in phase 2 trials for cluster headaches and anxiety. [19] DMT is being studied for depression. [20]
Dizziness, blurred vision, dry mouth, hypertension, nausea, increased or decreased body temperature, or feeling flushed are the common (>10%) non-psychiatric side effects. All these adverse effects are most pronounced by the end of the injection, dramatically reduced 40 minutes afterward, and completely disappear within 4 hours after the injection.
[5] [21] [1] [4] In fact, there may even be sensitization to the effects of 5-MeO-DMT. [4] The lack of tolerance development with 5-MeO-DMT may be due to biased agonism of the serotonin 5-HT 2A receptor. [5] More specifically, 5-MeO-DMT activates the G q signaling pathway of the serotonin 5-HT 2A receptor with much less potency in recruiting β ...
