What is the study measuring?

Primary Outcome Measures

Outcome Measure	Time Frame
Hamilton Depression Rating Scale (HAMD) Scores	This data will be assessed after 12 participants have completed the study and again after a completed sample size of 24 is achieved. The data will be presented at study completion (anticipated: 12 months after study initiation).
Hamilton Anxiety Rating Scale (HAMA) Scores	This data will be assessed after 12 participants have completed the study and again after a completed sample size of 24 is achieved. The data will be presented at study completion (anticipated: 12 months after study initiation).

Secondary Outcome Measures

Outcome Measure	Time Frame
Self-reported methamphetamine use	This data will be assessed after 12 participants have completed the study and again after a completed sample size of 24 is achieved. The data will be presented at study completion (anticipated: 12 months after study initiation).
Incidence of treatment-emergent adverse events	Adverse events will be reviewed monthly for safety concerns and presented at study completed (anticipated: 12 months after study initiation).
Percent of positive urine drug screens for methamphetamine	This data will be assessed after 12 participants have completed the study and again after a completed sample size of 24 is achieved. The data will be presented at study completion (anticipated: 12 months after study initiation).
