Psilocybin caused large significant positive changes to life purpose and altruism

> Altruism: Comparing LD-SS to HD-SS, the effect size was 1.36, which statisticians consider “very large.” Comparing LD-SS to HD-HS, the effect size was 1.95, considered “very large,” almost “huge.”

This is interesting to me. I wonder what a world would look like if everyone had therapeutic access to a substance that had a 'very large' effect size on increasing altruism.

> Compared with low-dose, high-dose psilocybin produced greater acute and persisting effects. At 6 months, compared with LD-SS, both high-dose groups showed large significant positive changes on longitudinal measures of interpersonal closeness, gratitude, life meaning/purpose, forgiveness, death transcendence, daily spiritual experiences, religious faith and coping, and community observer ratings. Determinants of enduring effects were psilocybin-occasioned mystical-type experience and rates of meditation/spiritual practices. Psilocybin can occasion enduring trait-level increases in prosocial attitudes/behaviors and in healthy psychological functioning.

The science seems pretty clear by now: psilocybin can have dramatic positive effects. How much longer can people claim this stuff is banned because it's dangerous? Beer and cheeseburgers are probably worse.
