A system for treating addictions includes genetic testing to determine the presence of allelic variants of genes shown to be associated with impulsive/addictive behaviors and a tailored rehabilitation regimen of specific physical exercise, special diet and particular dietary supplements to optimize the way mood elevation is achieved in the patient. The system further includes individual and group counseling and initial oxygen therapy. The genetic testing assesses the presence of gene polymorphism in at least one of D2 dopamine receptor gene (DRD2), dopamine transporter gene (DAT1), dopamine beta-hydroxylase gene (DBH) and serotonin transporter (SERT) gene. The dietary supplements are tailored to stimulate production of neuromediators or neurotransmitters, depending upon the polymorphism determined. The exercises include static and dynamic routines also tailored to the results of the genetic testing. After completion of the inpatient portion of the system, further therapies include daily exercise and dietary supplement programs tailored for each polymorphism discovered.
