It seems the design of this study is questionable.

Since they couldn't blind the psylocybin group from the effect, they gave 1mg daily to the SSRI group.

Basically it's a study that compares psylocybin with SSRI + psylocybin micro dosing.

They claim that the micro dose don't have an effect, but there is not a large body of evidence to support that claim.
