Drug dependence: some research issues.

This paper examines some problems of drug dependence, stressing the importance of a balanced approach. Consideration must be given to the demand for, as well as the supply of, drugs. Without a demand, there would be no continuing supply of man-made agents and no need to control the availability of naturally occurring agents.To achieve a balanced approach, increased research is needed into the effects on man of taking various dependence-producing drugs (particularly when these are used for long periods of time), the natural history of drug taking, the relative effectiveness of various preventive, therapeutic and restorative approaches and techniques, and means of identifying substances that, because of their dependence-producing properties, are apt to induce individual or public health problems. Attention is also called to some problems that may inhibit, but do not preclude, the initiation of studies in the field of drug dependence.
