Abstract

Essence

Survey participants who took psychedelics with a romantic partner reported greater shared understanding and more positive relationship changes than those who did not take them together.

Evidence

This cross-sectional survey of 798 participants, including 81 couples, used multilevel dyadic analyses and found that taking a psychedelic together was associated with greater shared reality and better relational outcomes, while shared reality mediated those positive changes.

Caveat

The evidence is limited by the cross-sectional design and low dyadic participation, so the findings cannot show that shared psychedelic use caused the relationship changes.

Simplified

The resurgence in research with classic psychedelics (e.g. LSD, psilocybin) underscores their potential for improved well-being; however, the interpersonal context and mechanisms of psychedelic impacts remain unknown. In a sample of 798 participants (81 couples), this survey study tested whether use of a psychedelic with a romantic partner (v. not together) was associated with couples' shared understanding (i.e. shared reality) and changes in relational well-being. Multilevel dyadic analyses provided overwhelming support for hypotheses that taking a psychedelic together would be associated with greater shared reality and more positive relational changes (e.g. improved physical intimacy, emotional closeness, satisfaction). Shared reality mediated positive relational changes. Taking a psychedelic alone was indirectly associated with the decision to end a romantic relationship. Although limited by cross-sectional design and low dyadic participation, results emphasize the importance of a socially informed approach to the development of psychedelic therapies, with potential to increase treatment effectiveness and mitigate harms.
