An 11-year follow-up of a network of cocaine users.

This paper presents findings from an exploratory 11-year follow-up study of a small network of cocaine users. These findings suggest that while serious abuse potential exists, addiction is not a uniform outcome of sustained use and that long-term controlled use is possible. In all, four types of career use pattern are described, in addition to one case of regular abuse.
