This report examines heroin use careers within a sample of 147 Black male heroin addicts and their nonaddicted friends. Based on the extent of their heroin use, subjects were classified into the following subgroups: "light" experimenters, "moderate" experimenters, "heavy" experimenters, and addicts. Our findings indicate that no single career line of pattern characterizes all heroin users. While some users quickly progress from initiation to heroin to regular, intermittent use or "chipping" to daily heroin use and physical dependence, others are deflected at various points along the way. In this report we describe some of the sociobehavioral processes or career contingencies associated with movement from one level of heroin use to the next.
本报告研究了147名黑人男性海洛因成瘾者及其未成瘾朋友样本中的海洛因使用历程。根据他们使用海洛因的程度，将受试者分为以下亚组：“轻度”使用者、“中度”使用者、“重度”使用者和成瘾者。我们的研究结果表明，没有单一的模式能表征所有海洛因使用者的历程。虽然一些使用者从开始使用海洛因迅速发展为定期、间歇性使用或“偶尔使用”，再到每日使用海洛因并产生身体依赖，但另一些使用者在这个过程中的不同阶段出现了偏离。在本报告中，我们描述了一些与从一个海洛因使用水平过渡到下一个水平相关的社会行为过程或历程突发事件。
