Neuroimaging evidence suggests that some patients diagnosed as being in a persistent vegetative state are actually conscious. This paper critically examines that evidence, arguing that while alternative interpretations remain possible, it strongly suggests consciousness in some patients. However, the ethical significance is less than often assumed. Different kinds of consciousness have different moral weight: phenomenal consciousness (qualitative feel) makes patients moral patients whose welfare matters, but only access consciousness (global availability of information to cognitive systems) confers personhood with full moral status. Further research is needed to determine whether these patients possess the sophisticated access consciousness required for personhood.

Consciousness is relevant to three distinct ethical issues: an entity's moral status, moral responsibility for actions, and the acquisition of moral knowledge. Despite these different connections, it remains unclear what exactly about consciousness makes it intuitively important for each area. The chapter explores whether there might be a common thread linking these issues, concluding that this possibility remains open.

As interest in psychedelics like psilocybin, ketamine, and MDMA revives and their legal status changes in many places, ethical guidelines are urgently needed for both medical and non-medical use. This paper argues that focusing only on medical applications neglects potentially valuable uses in other contexts and raises ethical issues including hype, exceptionalism, informed consent, therapeutic touch, data collection, and balancing access with safety. The authors call for renewed attention to the treatment-versus-enhancement distinction from bioethics and stress that guidelines should be flexible and context-sensitive. They recommend incorporating diverse stakeholder perspectives and cross-sector collaboration in future research and policy for psychedelic bioethics.
