Obesity and substance abuse during adolescence have reached epidemic proportions, and both are among the leading major public health problems in the United States. There is a significant amount of weight and Body Mass Index (BMI) gain in adolescent ex-addicts during supervised and confirmed abstinence from drugs and alcohol. The primary purpose of this secondary data analysis was to examine the effectiveness of two interventions implemented to address weight management in residential facilities treating adolescent substance use disorders. The secondary purpose was to establish if the outcome was a function of mandated smoking cessation and prescribed psychotropic medications. The results of the study suggest adolescents experienced weight gain in all groups, however there was no interaction effect for smokers and those adolescents on psychotropic medication for either outcome variable.
