Objective

Methadone maintenance treatment MMT was introduced to China in 2004 to reduce the harm of injecting drug users IDUs. However, little is known about continued drug use, especially methamphetamine MAMP, among MMT patients.

Methods

A survey was conducted among patients attending five major MMT clinics in Dehong Prefecture in 2014 to investigate the heroin and MAMP use and their associated risk factors. Participants were administered with face-to-face interviews, and urine tests for morphine and MAMP.

Results

A total of 2,121 were eligible and participated in the study. Among them, 220 10.4% were only positive for morphine, 12.9% were only positive for MAMP, and 196 9.2% were positive for both morphine and MAMP. Compared with neither use of heroin nor MAMP during MMT, heroin use not using MAMP was associated with ethnicity, shorter duration of MMT, lower dose of methadone, and having had no more than two sex partners in the past year; MAMP use not using heroin was associated with ethnicity, longer duration of MMT, higher dose of methadone and being aged <30 years vs. ≥50 years; use of both heroin and MAMP was associated with being Dai minority vs. Han, a marital status of divorced or widowed, having used drugs for ≥10 years and shorter duration of MMT.

Conclusion

These findings indicate the complexity in the treatment of heroin users and underscore the importance in prescribing appropriate methadone dosages in order to reduce both heroin and MAMP use.
