A 54-year-old man with terminal throat cancer received a single dose of LSD (100 μg) as part of psychedelic-assisted therapy delivered at his home. The treatment helped him experience relief from existential distress and feelings of peace. Six months later, he was in better psychological health, more motivated to pursue meaningful activities, and had discontinued pain medications while maintaining stability. This case demonstrates that psychedelic therapy can be safely administered at home for patients with life-threatening illnesses seeking existential relief.
