A discriminant function analysis was performed with data from 409 high-risk heroin addicts at intake into a methadone maintenance treatment program to determine the characteristics of cocaine users. Cocaine users presented a higher-risk profile for human immunodeficiency virus (HIV), engaged in a wider variety of criminal activities, were more likely to be African-American, reported more alcohol use, and showed more signs of psychological disturbance. A second discriminant function analysis determined that crack smokers differed from non-crack cocaine users in ethnicity, alcohol use, criminal activity, needle use, and marital status. Heroin addicts who use cocaine, in particular crack, represent a sub-group at higher risk and in need of targeted treatment planning and monitoring.
对409名进入美沙酮维持治疗项目的高危海洛因成瘾者在入院时的数据进行了判别函数分析，以确定可卡因使用者的特征。可卡因使用者呈现出更高的人类免疫缺陷病毒（HIV）感染风险，从事更多种类的犯罪活动，更有可能是非裔美国人，报告有更多的酒精使用情况，并且表现出更多心理障碍的迹象。第二次判别函数分析确定，吸食快克可卡因者在种族、酒精使用、犯罪活动、针头使用和婚姻状况方面与非快克可卡因使用者不同。使用可卡因，尤其是快克可卡因的海洛因成瘾者，是一个风险更高的亚群体，需要有针对性的治疗规划和监测。
