To date, however, there has been little evidence about smoking patterns among people receiving opioid-dependence treatment in developing countries. We examined self-reported nicotine dependence and associated factors in a large sample of opioid-dependent patients receiving methadone mai...

Pain and cigarette smoking are very common in heroin-dependent patients (HDPs) receiving methadone maintenance treatment (MMT) and both have substantial negative effects on HDPs' physical and mental health. Nevertheless, very few studies have assessed the relationship between the two in HDPs. This study examined the association between pain intensity and smoking in Chinese methadone-maintained ...

Managing pain in patients with heroin addiction is challenging, because most pain medications are addictive. A promising way to relieve pain of heroin addicts is to identify and address modifiable psychosocial factors associated with pain. This study examined the association between loneliness and pain intensity in Chinese heroin addicts receiving methadone maintenance treatment (MMT). A consec...

UNLABELLED Following the findings of perceived poor sleep and of chronic pain among former heroin addicts, current methadone maintenance treatment (MMT) patients, and its possible relation to methadone dose, we studied these patients' objective sleep parameters. Former heroin addicts maintained on "Low" (n=19, <80 mg/d) or "High" (n=25, >150 mg/d) methadone doses, underwent one-night polysomnog...

Patients from five MMT clinics were divided into three groups receiving MMT only, MMT with counseling psychology (CP) or MMT with contingency management (CM). A five-year follow-up was carried out with daily records of medication, monthly random urine...

We review drug abuse treatment as a means of preventing infection with HIV. Thirty-three studies, with an aggregate of over seventeen thousand subjects, were published in peer-reviewed journals from 1988-1998. Research on the utility of drug abuse treatment as an HIV prevention strategy has focused primarily on methadone maintenance treatment (MMT) rather than other modalities such as residenti...

BACKGROUND There is equivocal evidence regarding whether people who use heroin substitute heroin for alcohol upon entry to methadone maintenance therapy (MMT). We aimed to examine the impact of MMT enrolment on the onset of heavy drinking among people who use heroin. METHODS We derived data from prospective, community-based cohorts of people who inject drugs in Vancouver, Canada, between Dece...

Continuous abstinence was associated with a longer duration of MMT treatment, but there was no significant association between abstinence and past-y...
