Black men who have sex with men (BMSM) are highest risk for HIV seroconversion in the United States. Little attention has been paid to marijuana use among BMSM and potential for HIV risk. A sample of 202 BMSM was generated through respondent driven sampling. The relationship between differential marijuana use and both HIV risk behavior and social network factors were examined using weighted logistic regression. Of the BMSM in this sample 60.4 % use marijuana in general and 20.8 % use marijuana as sex-drug. General marijuana use was significantly associated with participation in group sex (AOR 3.50; 95 % CI 1.10-11.10) while marijuana use as a sex drug was significantly associated with both participation in condomless sex (AOR 2.86; 95% CI 1.07-7.67) and group sex (AOR 3.39; 95% CI 1.03-11.22). Respondents with a moderate or high perception of network members who use marijuana were more likely to use marijuana both in general and as a sex-drug. Network member marijuana use, while not associated with risk behaviors, is associated with individual marijuana use and individual marijuana use in the context of sex is associated with risk practices. Targeting interventions towards individuals and their respective networks that use marijuana as a sex drug may reduce HIV risk.
在美国，与男性发生性关系的黑人（BMSM）感染艾滋病毒血清转化的风险最高。人们很少关注BMSM群体中的大麻使用情况及其潜在的艾滋病毒风险。通过应答者驱动抽样选取了202名BMSM作为样本。使用加权逻辑回归分析了不同的大麻使用情况与艾滋病毒风险行为以及社交网络因素之间的关系。在这个样本中的BMSM中，60.4%的人一般会使用大麻，20.8%的人将大麻用作性药。一般使用大麻与参与群交显著相关（调整后比值比[AOR]为3.50；95%置信区间[CI]为1.10 - 11.10），而将大麻用作性药则与无保护性行为（AOR为2.86；95% CI为1.07 - 7.67）和群交（AOR为3.39；95% CI为1.03 - 11.22）均显著相关。对使用大麻的网络成员有中度或高度认知的受访者更有可能一般使用大麻以及将大麻用作性药。网络成员使用大麻虽然与风险行为无关，但与个人使用大麻有关，并且在性行为中个人使用大麻与风险行为相关。针对将大麻用作性药的个人及其各自的社交网络开展干预措施可能会降低艾滋病毒风险。
