Tell Your Children is a well-written, well-researched, and easy to read book that outlines the relationship between marijuana use, mental illness, and violence. Berenson marshals the evidence and lays out his case in a compelling manner that is largely grounded in science yet remains accessible to the lay reader. As such, this book is a must-read for young people and parents alike, as well as for state legislators grappling with the issue of marijuana legalization.
