Abstract: Due to the experience of drug abuse, the identity of community drug rehabilitation people is solidified by social misunderstandings and prejudices. And the single identity leads to the lack of sustained motivation in community drug rehabilitation. Multi-level identity construction from the perspective of social identity enables individuals to obtain different emotional experience stimuli in different transformations of identity, providing motivation for continuous transformation. Peer education service for the community drug rehabilitation people in S city builds three levels of identity, "peer candidate-quasi peer counsello-peer counsellor". Activities such as salons, growth groups, counseling and service in peer education are designed according to different levels of identity, so that the community drug rehabilitation people can obtain different emotional experiences and corresponding identities, ultimately achieving the goal of "self-help, mutual help and helping society" and gaining social recognition. In addition to individual subjectivity, the community drug rehabilitation people also need more support and help from society for their returning and integration.

Key words: social identity, community detoxification rehabilitation, identity construction, peer education
