Just Say Know! With drug education for children more important than ever, this nonfiction book draws on the experiences of the NY Times bestselling father/son team of David and Nic Sheff to provide all the information teens and tweens need to know about drugs, alcohol, and addiction. From David Sheff, author of Beautiful Boy (2008), and Nic Sheff, author of Tweak: Growing Up on Methamphetamines (2008), comes the ultimate resource for learning about the realities of drugs and alcohol for middle grade readers.      This book tells it as it is, with testimonials from peers who have been there and families who have lived through the addiction of a loved one, along with the cold, hard facts about what drugs and alcohol do to our bodies. From how to navigate peer pressure to outlets for stress to the potential consequences for experimenting, Nic and David Sheff lay out the facts so that middle grade readers can educate themselves.
