Tell Your Children: The Truth About Marijuana, Mental Illness and Violence

Tell Your Children: The Truth About Marijuana, Mental Illness and Violence is a 2019 book by Alex Berenson. In it, Berenson makes claims that cannabis use directly causes psychosis and violence, claims denounced as alarmist and inaccurate by many in the scientific and medical communities. Scientists state that Berenson is drawing inappropriate conclusions from the research he cites, primarily by inferring causation from correlation, as well as cherry picking data that fits his narrative, and falling victim to selection bias via his use of anecdotes to back up his assertions.

The title "Tell Your Children" was also the original title for Reefer Madness, a 1936 American propaganda film which gained cult popularity in the 1970s for its alarmist claims about cannabis. In an interview, Berenson said he made this choice deliberately: "I expected I would face serious backlash for this book and instead of running from it I decided to lean in."
