Heroindependents were randomly assigned to usual treatment with or without CET combined with BT.
Craving, skin conductance (SC), and muscle electromyography (MEG) were recorded.
After treatment, the craving, SC and MEG in experiment group were lower than control group.
Experimental group had a greater decrease in craving, SC, and MEG from baseline after the treatment.
CET combined with BT is effective in reducing craving in heroin dependents.
