Sequence B(n=20) receive EAR acupressure alone for four weeks first, and followed by one week wash-out period, then ear acupressure combined with electroacupuncture for another four weeks. Measures of methadone dosage and using the craving visual analog scale (VAS) to assess the craving severity for 8 weeks.
