Area of Science:

• Psychology
• Psychopharmacology
• Sociology

Background:

• Growing interest in the psychological benefits of psychedelic substances.
• Need to understand the impact of psychedelics on human connection and relationships.

Purpose of the Study:

• To systematically review existing literature on the association between psychedelic drug use and intimacy.
• To synthesize findings on how psychedelics affect various aspects of interpersonal connection.

Main Methods:

• Systematic literature review of 5,902 studies, with 19 meeting inclusion criteria.
• Analysis of studies with diverse methodologies, including laboratory experiments and retrospective self-reports.

Main Results:

• Laboratory studies consistently reported positive intimacy outcomes: enhanced relationship satisfaction, connectedness, empathy, and reduced social anxiety.
• Retrospective self-reports showed mixed results, with six studies indicating positive effects (e.g., closeness, interconnection) and four reporting negative experiences (e.g., distrust, dissatisfaction).

Conclusions:

• Psychedelic drug use in research-controlled settings is associated with predominantly positive effects on intimacy.
• Further research is required to determine optimal settings and long-term impacts of psychedelics on intimacy and relationships.
