Methamphetamine (MA) use is of great concern in the state of Utah (UT) because it is the primary drug threat in the state, and accounts for 15.6% of substance abuse treatment admissions. It UT, MA is more widely abused than heroin, cocaine, or prescription drugs, and it's the primary drug of choice in females between the ages of 18 and 24 years. Depression among females is also a great concern in UT. Females are prescribed antidepressants at a rate of more than twice that of males. Consistent research findings have reported a prevalence of major depressive disorder (MDD) in female MA users as being two to three times greater than males. There are limited treatment options for treating MDD in female MA users. Limited studies of creatine monohydrate supplementation in adolescent females with MDD who have not responded to SSRI-treatment suggest that creatine is safe and reduces depressive symptoms, but there are no reports of creatine supplementation in depressed female MA users.

The primary hypothesis of the study is that eight weeks of oral creatine supplementation will result in improvements in depression rating scores in female MA users. Secondary hypotheses include the following: 1) creatine supplementation will result in a decrease in the number of positive MA screens; 2) NAA and Cr concentrations will increase after eight weeks of oral creatine supplementation; and 3) PCr/β-NTP levels in the frontal lobe using 31P MRS will increase after eight weeks of creatine monohydrate oral supplementation.
