Researchers at Johns Hopkins gave psilocybin to healthy participants after they had undergone a 1–2 month preparatory training in meditation and spiritual practice (Griffiths et al. 2018). The results provided evidence that high support for spiritual practices increased both the acute and enduring effects of psilocybin.
In another recent study aimed at evaluating the synergistic effects of meditation and psychedelics, psilocybin was given to expert meditators during a meditation retreat (Smigielski et al. 2019). Remarkably, during acute drug effects, experienced meditators were able to remain engaged in their usual meditation practice and psilocybin was perceived as deepening the meditative state, without anxiety.
A study based on an online survey assessed the relationship between religion and mystical experiences (Neitzke-Spruill et al. 2018). The findings indicated that respondents who used psychedelics for specifically religious purposes, as well as those who identified with a religion, were more likely to score higher on the Mysticism Scale than those who did not.
A survey conducted by our collaborators at Imperial College aimed to evaluate the possibility of predicting acute and longer-term responses to psychedelics based on personality traits or other prior factors (Haijen et al 2018). The authors reported that having “clear intentions” for the experience as well as the ‘absorption’ personality trait was more conducive to mystical-type experiences.
