Psilocybin-assisted therapy for anxiety has primarily focused on clients with a chronic or serious illness who are experiencing end-of-life anxiety or existential distress which will be discussed in further detail in another module.
While there is limited evidence to support MDMA-assisted therapy for anxiety, some areas of focus have been social anxiety, particularly adults with autism. Danforth et al. (2018) found that at the 6-month follow up, the participants displayed positive results for their social anxiety.
There is limited but growing evidence to support ketamine and ketamine-assisted therapies in anxiety spectrum disorders. There are published case reports, case series, and controlled trials demonstrating positive effects and proof of concept. A 2019 review of the literature for ketamine effects on anxiety-spectrum disorders included OCD and PTSD, as the DSM-5 still acknowledges anxiety is a significant component of these conditions (Banov et al., 2019).
Please read the abstracts of the studies below which focus on ketamine-assisted therapy for anxiety.
A cross-sectional survey of 2510 adults looked at classic, plant-based psychedelic use and found that psychedelic use was linked to a better emotional wellbeing and a decrease in the symptoms of depression and anxiety. Although improvements were noted after just one use, increased psychedelic exposure increased these improvements with great magnitude (Raison et al., 2022).
