A review of studies on psychedelic-assisted therapy found no evidence that the number of therapy hours affects depression outcomes. The authors caution that this conclusion is tentative because the studies included small numbers of participants, varied widely in methods, and poorly documented the therapy provided. They call for future research to use more rigorous methods and standardized reporting to better understand the role of therapy.
