James Fadiman, an early psychedelic researcher, and co-author Jordan Gruber’s MICRODOSING FOR HEALTH, HEALING AND ENHANCED PERFORMANCE is the first comprehensive book on microdosing, using new research and extensive reports from individuals to describe the possibilities of the practice.

Microdosing is proving to be a safe and powerful approach to a wide range of health conditions and enhanced performance. Partly responsible for modern microdosing’s development and current popularity, the authors answer hundreds of questions, blending extensive research with detailed personal accounts from contributors worldwide. The book also contains wide-ranging microdosing history, research, and science.

People have microdosed successfully:

· to alleviate symptoms of depression, ADHD, chronic pain, and long COVID
· for enhanced focus, mental acuity, and physical abilities (including sports)
· to help taper off pharmaceuticals, especially antidepressants and stimulants
· to improve food habits, sleep, and relationships
· to become more aware of personal habit patterns, others’ feelings, and natural surroundings
· to reduce stress and anxiety
· to help over 30 specific health concerns

This book does not provide medical or legal advice. Readers should speak to their doctor before engaging in any course of microdosing.
