Patients who have a DSM 5 diagnosis of Methamphetamine Use Disorder, if consented, will have serial doses of 56, 108, 164, and 216 mg of Methylphenidate sustained release (OROS methylphenidate) tablet with an increase in the dose used every day followed by five hours of post dose monitoring each day.

The dose will be administered as one dose daily after review of side effects, Blood Pressure had Heart rate, and a rapid urine drug screen. The dose will increase daily for four consecutive days.

Statistical methods / analysis
Most of the statistical plan is descriptive. We will tabulate the number of participants who completed all four days of the trial, the timing of any discontinuation, and the reason for discontinuation. We will graph the pooled data for each day over time. From previous work, we expect that there may be an increase in blood pressure and heart rate, which will decrease over time for each participant. We will compare the mean, median peak blood pressure, and heart rate by dose. We will report the interquartile range, and if the distribution is parametric, the standard deviation.

We will describe the mean results for the psychosis screener, Hamilton depression scale, Brief Craving scale and young mania rating scale.
