Co-using a low dose of MDMA with psilocybin or LSD is associated with less intense challenging experiences—such as grief and fear—and increased feelings of self-compassion, love, and gratitude, compared to using psilocybin or LSD alone. In a survey of 698 people planning to use these substances, the 27 who also took a low dose of MDMA reported these benefits without a reduction in mystical-type experiences or compassion. Medium-to-high MDMA doses did not show the same effects. The findings suggest MDMA may buffer against some difficult aspects of psychedelic experiences, but the study's small, non-experimental convenience sample limits certainty.
People who have used psychedelics, either currently or in the past, report higher levels of compassionate love, self-compassion, and life satisfaction compared to those who have never used psychedelics. Current users also show greater self-compassion and life satisfaction than past users. Lifetime mystical-type experiences are positively linked to these aspects of positive psychological functioning across all groups, not just among psychedelic users. The findings, based on a cross-sectional survey of 984 people, suggest that psychedelic use and mystical experiences may support well-being, but the study is limited by self-reporting, its cross-sectional design, and a homogenous sample.
