对云南省陇川县１９８２年以来的吸毒情况进行了分析，我们发现８２至８５年吸食鸦片的人数逐年增加。可是从８６年出现吸食或注射海洛因以后，吸食或注射海洛因的人数逐年增加．而吸食鸦片烟的人数却逐年减少。男性鸦片和海洛因的吸毒率均显著高于女性（Ｐ〈０．００１）．傣族和景颇族男性和女性的鸦片与海洛因吸毒率均显著高于汉族（Ｐ〈０．００１），男性和女性的鸦片吸毒率与文化程度呈反方向剂量反应关系（Ｐ〈０．００１）。我们认为，在继续作好辑毒和戒毒工作的同时，应该加强预防青少年吸毒工作的力度。 The situation of drug abuse in Longchuan County, Yunnan Province since 1982 was analyzed. We found that the number of opiate users increased every year from 82 to 85 years. However, the number of people taking or injecting heroin increased year by year since the introduction of heroin in 1986. The number of people who smoke opium is decreasing year by year. Drug abuse rates for both male opiates and heroin were significantly higher than those for women (P <0.001). The rates of opiate and heroin abuse among Dai and Jingpo men and women were significantly higher than those from Han (P <0.001). The rates of opiate drug abuse among men and women were inversely proportional to the educational level (P <0.001). We believe that efforts should continue to be made to prevent juvenile drug abuse while continuing to make good use of drug and drug detoxification.
