Eight-six heroin addicts were randomly divided into the treatment group by electroacupuncture plus Methadone and the control group by single Methadone for comparison of the therapeutic effects. Statistically there was no significant difference in the therapeutic effect (score reduction rate) between the treatment group and the control group (P＞ 0.05). In the treatment group, the dose of Methadone was half of routine dose, but the therapeutic effect was similar and side effect was less, in comparison with full dose in the control group.
