Alcohol use problem is defined as two levels separately, level one is excessive and hazardous drinking, level two is alcohol abuse and dependence. METHODS: This is a prospective follow-up study. Study population includes 438 patients retaining more than 6 months in MMT from the Fong-Yuan Hospital and Tau-Yuan Psychiatric Center. Demographic and clinical characteristics were collected for each patient at the beginning, and treatment-related variables were collected during treatment process. Excessive drinking and hazardous drinking, alcohol abuse and dependence were measured by Chinese Version Alcohol Use Disorders Identification Test (Chinese Version AUDIT) and breath alcohol concentration. RESULT: The prevalence rate of excessive drinking and hazardous drinking among MMT patients is 31.4%, and the prevalence rate of alcohol abuse and dependence is 12.0%. The predictors of excessive and hazardous drinking among MMT patients include attendance rate more than 90%（OR=0.54，95%CI=0.30-0.97）, age older than 35 years old（OR=0.48，95%CI=0.27-0.86）,and alcohol use at intake（OR=5.30，95%CI=2.87-9.76） is a risk factor. The predictors of dropout among MMT patients include methadone dose less than 60 mg (Wald test p-value<0.001), without governmental fund (Wald test p-value<0.001). CONCLUSION：The high prevalence rate of excessive and hazardous drinking among MMT patients underscores the needful screening and intervention for alcohol use problem .Those patients who are younger and have poor adherence, alcohol use at intake should be screened for excessive and hazardous drinking.
