[Epidemiologic information on the improper use of psychoactive substances. Some strategies applied in Argentina].

In seeking epidemiologic information on the improper use of psychoactive substances it makes good sense to take advantage of available institutional resources, especially in situations where more usual research resources are in short supply or altogether lacking. This article describes several studies that availed themselves of institutional resources in Argentina for the purpose of obtaining this type of information. One of these was carried out by personnel at several rehabilitation centers dealing with problems related to improper use of psychoactive substances; another obtained information from physicians and auxiliary personnel providing emergency treatment at three general hospitals; and another used the facilities of labor organizations to investigate workers' problems. All in all, these projects show how innovative approaches can help to obtain key substance abuse information; they could also serve as worthwhile models for those interested in carrying out similar work with limited resources.
