The study in this book focused on the Minnesota Adult and Teen Challenge in Minneapolis, Minnesota, USA. However, the subjects of the study came from different states for treatment at MNTC in Minneapolis. As a part of the study, different Adult and Teen Challenge (ATC) locations were reviewed. For the residential programs, the basic components are the same. MNTC was the chosen focus for this study as it was near the author’s home, thus making access to staff and graduates easier for the study.

The graduates in this study on substance use disorder treatment were from Minnesota, North Dakota, South Dakota, and one from Florida. The reasons for their treatment in Minneapolis, Minnesota, were varied. Many who came from Minnesota were at MNTC as part of a plea agreement with the courts, which offered reduced time if they completed the program. Others were at MNTC because a relative was trying to help them with their substance abuse and sent them to this location.

According to the Adult and Teen Challenge USA website https://teenchallengeusa.org/, there are 220 locations in North America alone. Help is available if someone just looks for it.
