There is a lack of evidence of effectiveness of the included interventions. Motivational interviewing and some family interventions may have some benefit. Cost-effectiveness has not yet been addressed in any studies, and further research is needed to determine whether any of these interventions can be recommended.
Community-based trial to prevent drug use among youths in Yunnan, China.
This study evaluated a community-based program in China to prevent initiation of drug use in young men.
                Similar intervention and control areas were selected. Village leaders, teachers, and women and youth leaders were recruited to participate in the program. Community activities were organized and intervention activities in schools were implemented. Incidence of new drug users was estimated.
                There was a 2.7-fold greater reduction in drug use initiation in the intervention area (1.59% vs 0.60%). Reduction was highest among males aged 15 to 19, single men, illiterate men, and the Jingpo minority. HIV/AIDS knowledge and attitudes and recognition of drug problems were all significantly better in the intervention area.
                Community-based intervention programs to prevent drug use can be successful in rural areas of China.
