This book investigates the multifaceted behavioral and social consequences of marijuana use. Ernest L. Abel, a researcher in the field, compiles existing knowledge to examine how marijuana affects individual behavior, cognitive functions, and social interactions. The work synthesizes findings from various studies to present a comprehensive overview of the known effects, considering both potential benefits and drawbacks.

The book is likely to be regarded as a foundational text for understanding the early research into marijuana's effects. Its 1973 publication date suggests it captures the scientific understanding and societal discourse of that era. The work probably provides a comprehensive, albeit dated, overview of the psychological and social implications of cannabis use as understood at the time of its writing.
