Participants were able to participate in one or both phases of the study. Methamphetamine abusers were held as inpatients and abstained from methamphetamine use during the entirety of the study. Phase I covered the 1st week of abstinence and Phase II covered the next 3-4 weeks of abstinence. Control subjects participated as outpatients at timeframes which corresponded to the assessments taken of methamphetamine users. The following outlines the procedures in more detail. After initial telephone screening, in-person screening and recruitment procedures took place at the UCLA Neuropsychiatric Institute. Each methamphetamine abuser subject entered the study after completing an interview and questionnaires on drug use history, and providing a positive urine test for methamphetamine. The evaluation included a psychiatric diagnostic interview according to the Structured Clinical Inventory for DSM-IV (SCID-IV), a medical history and physical examination, blood tests [including a complete chemistry panel, hepatic panel, and tests for hepatitis-C and HIV]. Urine samples were also taken for drug screening of illicit drugs, and to test for pregnancy (female subjects). The methamphetamine abusers were then admitted to the General Clinical Research Center (CRC) and participated on a residential basis, where they were administered daily questionnaires about drug craving, withdrawal and mood. The current study makes available phenotype and genotype data, and interested investigators may contact the principal investigator regarding potential sharing of fMRI data.
