Volunteers at risk

An experiment is described in which three male volunteers, who fully understood the nature of the project, were given doses of heroin which could have led to addiction if the subjects had proved to be physiologically or psychologically vulnerable to developing a state of addiction. The experiment was discussed most carefully by the Ethics Committee of the unit where it was conducted, and the subjects were themselves the investigators. The objective was to learn about the initial stages of the adaptation to heroin, of which nothing was known as heroin addicts usually come to the doctor when the habit is firmly established. A physician, who has studied the subject of drug addiction in a special clinic, is the first commentator, the second a lawyer and the third an associate professor of social ethics. These three experts are not discussing the results or the methodology of the experiment but whether the decision of the Ethics Committe was the right one.
