In the past, adults told kids to "just say no." We say, "just say know." Know yourself. Figure out what you want in life. Weigh the risks of using. Know the truth and decide. David and Nic Sheff may be father and son, but they're also experts on drug and alcohol use and addiction. They've lived through it, and now they want you to learn from their experiences. This award-winning duo covers everything from marijuana legalization, to the opioid crisis, to peer pressure, and uses research, interviews, and testimonials to answer questions you might be nervous to ask out loud. This book isn't full of easy answers, because there are none. Instead, High provides factual, reliable information so you can make educated decisions without having to rely on rumors to get a glimpse of what drug and alcohol use and addiction really look like.
