本文对１１３例住院戒毒者进行了调查。从调查结果提示，鞍山地区毒品泛滥的特点之一是蔓延迅猛，始料不及，９３年迅猛增加为９０年的１４倍；特点之二是吸毒者应用毒品的种类变化很大，９０年以前所用毒品多为杜冷丁，以后为杜冷丁加海洛因，现在大多单用海洛因，由此可见已经由起初的医源性的被动使用麻醉品转变为积极寻求毒品的趋热；调查结果还提示，城市吸毒者占９０％，男性吸毒者近８０％，多为无业、个体及工人，因此应把城市２５－３０岁的无业及个体经营者视为高危人群，对其应加强毒品危害的教育及定期监测；关于戒毒机构的管理方式，我们进行了半封闭式与开放式两种管理方式对比，半封闭式虽然平均住院天数比开放式长８．２天，但疗效较好，两组疗效相比（Ｐ＜０．０５），呈显著性差异。 This article conducted a survey of 113 hospitalized drug addicts. From the survey results, it is suggested that one of the characteristics of drug abuse in Anshan area is that it spread rapidly and unexpectedly, rising rapidly in 1993 to 14 times of that in 1990. The second feature is that the types of drugs used by drug abusers vary greatly and are used 90 years ago Most of the drugs are pethidine, followed by pethidine and heroin, and most of them are now used alone. This shows that the initial iatrogenic passive use of narcotics has turned into an active drug seeking fever. The findings also suggest that urban drug use 90% of men and nearly 80% of male drug users are mostly jobless, self-employed and workers. Therefore urban unemployed and self-employed persons aged 25-30 should be regarded as high-risk groups and should be educated and regularly monitored for their drug hazards ; On the management of drug treatment agencies, we conducted a semi-closed and open comparison of two management methods, semi-closed although the average length of stay longer than open 8.2 days, but the effect is better, the two groups compared to ( P <0.05), showing significant differences.
