The Johns Hopkins group reported that psilocybin decreased clinician- and patient-rated depressed mood, anxiety and death anxiety, and increased quality of life, life meaning and optimism. Six months after the final session of treatment, about 80 percent of participants continued to show clinically significant decreases in depressed mood and anxiety, with about 60 percent showing symptom remission into the normal range. Eighty-three percent reported increases in well-being or life satisfaction. Some 67 percent of participants reported the experience as one of the top five meaningful experiences in their lives, and about 70 percent reported the experience as one of the top five spiritually significant lifetime events.
