Evidence suggests that cocaine dependence, similar to alcoholism, may have 2 subtypes, A and B (ie, type I and type II in the literature on alcoholism typology). Type A persons may develop cocaine dependence as a function of environmental influences, whereas type B persons may have certain premorbid risk factors that predispose them to a virulent form of cocaine abuse.

Ball et al studied 399 patients with cocaine abuse or dependence in the first multidimensional subtyping study of cocaine users. [39] The most common presentation, observed in 67%, was type A. Women and African Americans most commonly had type A dependency, whereas men and whites most commonly had type B dependency. Compared with persons with type A dependency, those with type B dependency had more severe abuse of alcohol and other drugs, addiction-related psychological impairment, antisocial behavior, and comorbid psychiatric problems.
