The investigators hypothesize that opioid use in African-Americans will be associated with hypodopaminergic alleles that alter the threshold for activating feelings of reward and pleasure within the dopaminergic system, and that these allelic frequencies will differ significantly from European Americans. Planned is a targeted system to study genetic risks for reward deficiency using risk gene panel to assign a genetic addiction risk score (GARS), comprehensive surveys to determine quality of life and exposure to stressors and trauma. This system will allow prediction of addiction and relapse potential and delivery of personalized treatment.

Individuals seeking treatment for Opioid Use Disorder in the Washington DC metro area will be recruited to this Study, which consists of 1) early pre-disposition diagnosis using the Genetic Addiction Risk Score (GARS); 2) Assessment of reward deficiency, co-morbid neuropsychiatric disease, quality of life/happiness, stressors/trauma and other psychometric measurements using validated questionnaires; Urine drug testing during actual treatment that uses comprehensive analysis of reported drugs to determine compliance with prescription medications and non-abstinence to illicit drugs; and 4) adjunctive treatment with neuroadaptogen amino acid therapy (NAAT), a glutaminergic-dopaminergic optimization nutraceutical (generic name: KB220) compared to placebo, aimed to prevent relapse by induction of dopamine homeostasis.

Inclusion Criteria:

• Must be able to consent and understand questions being asked during surveys
• Must be willing to undergo pharmacogenetic testing
• Must be able to swallow tablets

Exclusion Criteria:

The genetic data will be shared when compiled

within 18 months following completion of the study, and the cleaning of clinical and genomic data
