Psychedelics for Moral Bioenhancement in Healthy Individuals—A Violation of the Non-Maleficence Principle?

Several authors have advanced the idea that psychedelics such as psilocybin might be effective means for achieving moral bioenhancement (MBE). Here, I discuss some reservations on this assertion from both neuropharmacological and bioethical perspectives, and surmised that there is little, if any, good justification for such a claim. The indication of psychedelics for MBE is undermined by their hallucinogenic properties and the risk of adverse psychosis. There is also a lack of sound bioethical basis for using psychedelics to enhance morality. Based on our current understanding, the use of psychedelics specifically for MBE in healthy individuals would violate the ethical principle of non-maleficence. Unless there is unequivocal demonstration that psychedelics could enhance morality, or that new non-hallucinogenic derivatives become available, an indication for psychedelics in MBE would be untenable.
