目前的研究利用了123名在住宅治疗中的市中心吸毒者的样本，比较了(A)海洛因和不可卡因/可卡因、(B)可卡因和不海洛因以及(C)海洛因和可卡因的主要吸毒者的性危险行为(SRB)。其他分析还检查了冲动作为药物选择和SRB的中介因素。结果表明，吸毒者SRB高于吸毒者，吸毒者和吸毒者SRB处于中等水平。除了SRB的差异外，在不同药物的冲动方面也发现了类似的模式。冲动性在药物选择与SRB之间的关系中起中介作用。尽管需要进一步的研究来建立因果关系，但这些结果支持SBR与可卡因/可卡因之间的关系，并表明包括冲动在内的去抑制过程可能是这种关系的基础。(C)2004年，爱思唯尔爱尔兰有限公司出版。
The current study utilized a sample of 123 inner-city drug users in residential treatment, comparing sexual risk behavior (SRB) across primary users of (a) heroin and not crack/cocaine, (b) crack/cocaine and not heroin, and (c) both heroin and crack/cocaine. Additional analyses also examined impulsivity as a mediator of drug choice and SRB. Results indicated that SRB was higher in primary crack/cocaine users than in primary heroin users, with those using both drugs evidencing intermediate levels of SRB. Beyond differences in SRB, a similar pattern across drugs was found for impulsivity. Finally, impulsivity mediated the relationship between drug choice and SRB. Although further research is necessary to establish causal relationships, these results support a relationship between SBR and crack/cocaine, and suggest that disinhibition processes including impulsivity may underlie this relationship.
