This study will examine the effect of N-Acetylcysteine (NAC), an over-the-counter antioxidant supplement on brains of youth (ages 15-19) using magnetic resonance imaging (MRI). 55 adolescents will receive, in a counterbalanced order, a 10-day course of NAC 1200 mg twice daily and a subsequent 10-day course of matched placebo twice daily, separated by 11 days. Urine samples will be collected at screening and urine and blood samples will be collected before and after each course of medication treatment. Participants will receive a 1- hour MRI scan at baseline and after each treatment trial. There will be a control group of 30 adolescents who will undergo the screening and baseline visit only.
