This book, by Charles T. Tart, world famous authority on altered states of consciousness, describes the results of a landmark study of 150 experienced marijuana users. What do they actually feel vs. propaganda about marijuana? Effects on vision, hearing, touch, social interaction, sexual sensations, space and time perception, thinking processes, spiritual experiences and ESP are among the many discussed. This is what can happen in the natural settings people use marijuana in, not the artificial conditions of the laboratory.
“This book will become the standard work on the subjective effects of marijuana.”
