Methamphetamine substance use is common worldwide. No approved pharmacologic treatments for methamphetamine dependence exist. paliperidone are Second generation antipsychotics,and have effects of blocking dopamine2(D2) and 5-hydroxytryptamine 2A(5-HT) receptors neurotransmitters.To determine whether mirtazapine would reduce methamphetamine use among methamphetamine addicts.

Primary Outcome Measures:
  • Time (day) to first psychosis relapse from baseline to 84 days [ Time Frame: up to 84 days ]
    psychosis assessement was made once a week.Psychotic symptom relapse was defined as one or more of the following: (1) hospitalization for psychotic symptoms; deliberate self-injury or violent behavior, or suicidal or homicidal ideation that was clinically significant;25% increase in PANSS total score;for patients who scored >40 at randomization, or a 10-point increase for patients who scored ≤40 at randomization for two consecutive assessments (within 1 week), and (4) increase in prespecified individual PANSS items scores (P1, P2, P3, P6, P7 and G8) to ≥5 for patients whose score was ≤3 at randomization, or to ≥6 for patients whose score was 4 at randomization for two consecutive assessments (within 1 week)

Secondary Outcome Measures:
  • Change from baseline in PANSS total scores at 84 days [ Time Frame: up to 84 days ]
    psychosis assessment was made by PANSS once a week, and calculated the total scores

  • Change from baseline in CGI-S scores at 84 days [ Time Frame: up to 84 days ]
    general condition assessment was made by CGI-S once a week, and calculated the total scores

  • Change from baseline in Visual Analogue Scale (VAS) at 84 days [ Time Frame: up to 84 days ]
    Methamphetamine craving assessment was made by VAS once a week, and calculated the total scores

  • The time-to-first(day) positive methamphetamine urine test [ Time Frame: up to 84 days ]
    Made urine test once a week at hospital.

  • Treatment Effectiveness Score [ Time Frame: up to 84 days ]
    The sum of the number of METH-free urine samples submitted per participant

  • longest period of methamphetamine abstinence during the 84 days [ Time Frame: up to 84 days ]
    Made urine test once a week at hospital.

  • number of treatment day which calculated from randomization to the last visiting point [ Time Frame: up to 84 days ]
    record the follow up time
