Background: There have been few studies conducted on the oral health status of illegal drug users in China, affecting the development of preventive and therapeutic approaches. The aim of the present study was to investigate and analyze the oral health status of former heroin users treated with methadone in Chengdu, the capital of Sichuan Province in southwestern China.
Material/Methods: The presence of caries (decayed tooth and root), missing teeth, residual roots, dental prosthetic restoration and periodontal health were investigated in 445 former heroin users treated with methadone (317 males and 128 females). Their ages ranged from 20 to 59 years old.
Results: Among the study subjects, the prevalence of decayed/filled teeth was 64.72%, and the mean of decayed/filled teeth score was 2.92. The prevalence of decayed/filled roots was 21.80%, and the mean of decayed/filled roots score was 0.62. The prevalence of missing teeth was 31.46%, and the mean missing teeth score was 0.62. The prevalence of residual roots was 42.02%, with a mean score of 1.06. The rates of gingival bleeding, calculus, shallow pockets periodontal pocket, and deep periodontal pocket were 99.55%, 96.63%, 30.34%, and 2.70%, respectively.
Conclusions: The oral health status among the studied former heroin users in Chengdu was poorer than the general population. Better dental care for the former heroin users is needed to promote their oral health.

Objective: This study examined the predictors of self-efficacy in reducing risky injection behaviors among heroin users receiving methadone maintenance treatment (MMT). Method: The Methadone Maintenance Treatment Outcome Study was an 18-month prospective study from March 2007 to July 2008. Data collection was conducted in the substance use disorders treatment outpatient clinics of three hospitals in southern Taiwan. A total of 368 opioid-dependent heroin users (13.6% women) were interviewed at baseline and at 3-, 6-, 9-, 12-, 15- and 18-month follow-ups. The level of self-efficacy in reducing risky injection behaviors was repeatedly assessed using the Self-Efficacy Scale for HIV Risk Behaviors. Demographic and substance use characteristics, HIV serostatus, family function, depression, and pros and cons of heroin use were collected at baseline, and methadone dosage at each follow-up interview and the duration of retention in the MMT program were also recorded. Results: The results of the generalized estimating equation indicated that a lower educational level, concurrent methamphetamine use, a younger age at first heroin use, a lower methadone dosage, a higher level of depression, and a shorter duration of retention in the MMT program were predictive of a lower level of self-efficacy in reducing risky injection behaviors. Conclusions: This study found that personal and MMT-related factors were predictive of a lower level of self-efficacy among heroin users receiving MMT. Programs implemented to promote a higher level of self-efficacy should be provided to heroin users in the MMT program. (J. Stud. Alcohol Drugs, 73, 469-476, 2012).

The purpose of the study was to compare the detection rate of illicit drugs in urine and hair specimens. The samples were taken from subjects trying to regain their revoked driver’s license after a drug- or alcohol-related traffic offence. In 2010, we screened 14 000 urine and 3900 hair samples for amphetamines, methamphetamines, cannabinoids, cocaine, opiates, methadone, and benzodiazepines as well as for ethylglucuronide. We used the low threshold values of the new German guidelines for Medical Psychological Assessment (MPA). Positive screening tests were confirmed with gas chromatography-mass spectrometry (GC-MS), gas chromatography-tandem mass spectrometry (GC-MS/MS) or liquid chromatography-tandem mass spectrometry (LC-MS/MS). The results show that positivity rates for methamphetamines, MDMA, cocaine, and monoacetylmorphine were 1.7-, 5.7-, 3.8- and 9.3-fold higher in hair than in urine. In contrast, the detection rate for benzodiazepines was higher in urine than in hair (oxazepam, 0.21% versus 0%, nordiazepam 0.10% versus 0.03%). The positivity rate in hair for ethylglucuronide was 6-fold (12.7%) that for urine testing (2.1%). The study reveals that in the control of abstinence in the context of driving license re-granting there are in part large differences of positivity rates for some drugs or metabolites between hair and urine samples. These differences should be kept in mind by physicians and psychologists in traffic medicine who are ordering the drug testing. Copyright © 2012 John Wiley & Sons, Ltd.
