Father and son David and Nic Sheff draw on their personal experiences to explore the effects of drug use on young people.

Drug use is hugely prevalent across the U.S. and the world. Millions suffer the effects of substance abuse, however mild they may think their usage is.

Drug addiction totally changes the brain chemistry, and can make people almost unrecognisable, which can rip families apart and lead to tragic consequences.

In their 2019 book, High, bestselling authors and father and son David and Nic Sheff unravel the dangers of drug use, particularly in teenagers, detailing the specific risks of various substances.

Drawing on their own journey through son Nic's addiction, the Sheffs provide guidance for teenagers and their families about what to look out for, how to understand the effects of different drugs, and how to avoid addiction.
