Background: According to statistical data of the Vietnam Ministry of Health, there were 124,223 people with positive HIV, 23,661 AIDS patients and 13,649 AIDS- related deaths up to April 30th 2007. The major transmission route is injection. Objectives: (1) To compare the characteristics of drug use in users with different time. (2) To describe the health issues and health service access of young male drug users. Subjects and method: A cross-sectional survey was carried out using a combination of medical anthropology and epidemiology methods. 1.115 young male drug users in Ha Noi between September 2004 and September 2005 were divided into 4 groups of the equivalence number, but with different drug using history. Results and conclusion: The newer drug users (within 2 years) started using drug later than the older ones, more of them started using by injecting; they transfer from smoking/sniffing to injecting as well as trying and using more different types of drugs together in shorter time than others. The proportion of HIV (+) infection in these people was higher, which states the necessity of intervention to help them enhance their knowledge to prevent HIV infection amongst themselves. Mental health care is also needed for drug users, the demand for mental health care increases with the time of drug usage.

OBJECTIVE: To explore the epidemic situation of cannabis use among drug users with compulsory detained detoxification treatment in China. METHODS: Using the data from the Drug Abuse Population Estimation in the Key Cities of the Ministry of Public Security, we analyzed the sociodemographic characteristics and substance use of cannabis abusers with compulsory detained detoxification treatment in 55 provincial capital cities and key cities of China. Chi-square test, Fisher exact test and Kruskal-Wallis rank sum test were used to compare the prevalence of cannabis, heroin, synthetic and mixed drug use among patients with detoxification treatment, as well as the differences in polydrug use and areas among cannabis users. RESULTS: In the study, 25 366 drug users with compulsory detained detoxification treatment were recruited, of whom 2.2% (546/25 366) used cannabis in the previous year before the treatment. The proportion of males was 83.5%, and the proportion of ethnic minorities was 41.0%. Those who received junior high school education or above accounted for 30.8%, and the unemployed accounted for 44.1%. The average age was (33.3±8.2) years, the average age of beginning drug use was (24.8±7.7) years, and the average duration between the first drug abuse and first detoxification treatment was (5.4±4.6) years. The prevalence of cannabis use was higher among those drug users who were 35-year-old and younger, ethnic minorities, employees and residents in Xinjiang. Of the cannabis users, 91.4% used polydrug, 13.6% combined with heroin alone, 42.1% combined with synthetic drugs alone and 35.7% combined with both of heroin and synthetic drugs. Of the cannabis users, 49.6% came from 3 regions: Xinjiang Uygur Autonomous Region, Jiangsu Province and Shanghai City. The cannabis users in Xinjiang had a high proportion of ethnic minorities who received junior high school education and below. Moreover, 79.6% of them combined cannabis use with heroin. The cannabis users in Jiangsu, Zhejiang and Shanghai areas had a higher proportion of ethnic Han who received better education (high school and above). Moreover, 92.7% of them combined cannabis use with methamphe-tamine. CONCLUSION The prevalence of cannabis use among the population with compulsory detained detoxification treatment is higher than that among drug users under surveillance, but there are obvious regional cluster effect and high possibility of polydrug abuse. Thus, it's important to strengthen the monitoring of cannabis use, to increase the control of cannabis and to formulate China's anti-cannabis policy among different population.

OBJECTIVETo explore the factors associated with retention in a community-based methadone maintenance treatment(MMT) among drug users in Urumqi.

METHODSWith national MMT guideline( drift) for heroine addicted drug users, local heroine-dependent people were admitted to community-based MMT program affiliated to Xinjiang Uigur Autonomous Region Center for Mental Health. Data on outpatients' social-demo characteristics, baseline behaviors on drug use and daily stabilized dose of drugs were entered to MMT database.

RESULTSUp to 10, Feb. , 2006,353 persons withdrew MMT treatment among 709 heroin dependant drug users. Between 11, Aug., 2005 and 10, Feb., 2006, with median duration as 77 days, cumulative drop-out rate of 90 days and 180 days after first dose of MMT were 73.8% among 455 and 99.4% among 355 drug users, respectively. The incidence of drop-outs was 29.8 per 100 person-month. The median length of stay (days) in MMT was 68.0 (95% CI: 59.0- 78.0). Correlates of retention were found as: Being Uigur(HR = 1.35;95% CI :1.09-1.67), duration of drug use (HR =0.74; 95% CI:0.55-0.99) and stabilized dose(HR = 0.60;95% CI: 0.48-0.74) was found in multiple Cox proportional hazard regression model.

CONCLUSIONRetention of MMT among drug users in Urumqi was low. Uigur people should be given individual counseling to help them increase the compliance rate. Within the ranges of clinic dosage, adjustment of the methadone dose on an individual base might serve as an appropriate approach to increase the effectiveness of the program.
