Research Paper: The Psychological Effects of the Administration of Psychedelics on the Minds of Healthy Individuals: A Systematic Review

This comprehensive paper offers a structured and thematic review of contemporary research on the phenomenological effects of classical psychedelics in healthy individuals. Synthesizing findings from the past three years, it provides a clear, organized analysis of how users describe their subjective experiences during psychedelic states.

Key themes include various modes of communication with perceived entities—ranging from intuitive to kinesthetic interactions—mystical-type experiences characterized by intense euphoria or distress, and the inter-relational roles these entities play, from nurturing to intimidating. The research methodology follows established qualitative guidelines (SPIDER and thematic synthesis), ensuring credibility and academic rigor.

This review is ideal for psychology students, academic researchers, and professionals interested in consciousness studies, mental health, or psychedelic therapy. It offers a valuable synthesis of emerging evidence and presents thoughtful insights into both the short- and long-term psychological impact of psychedelic substances.
