It is particularly important to survey substance use trends in populations most impacted by the consequences of substance use. Men who have sex with men (MSM) exhibit rates of methamphetamine and other substance use that exceeds those observed among other populations in the United States. Such substance use has been associated with numerous negative health sequelae.
An outreach program performed street encounters with 5599 unique substance-using MSM from January 1, 2008 through December 31, 2011 to collect data on self-reported sociodemographics and recent substance use. Data were aggregated into six-month cohorts for comparisons of recent substance use patterns across time
Participants averaged 33 years of age (SD=8), most were Caucasian/white (47%) or Hispanic/Latino (32%), and the self-reported HIV seroprevalence rate was 13.4%. Across cohorts, reported use of alcohol (range=91-93%), marijuana (range=36-46%), and/or methamphetamine (range=23-27%) was common; prevalence of amyl nitrite (max=14%), ecstasy (max=12%), powder cocaine (max=8%) and/or crack cocaine (max=4%) use, although less common, were still elevated relative to the United States general population.
Methamphetamine and other substance use remained common among substance-using MSM, demonstrating the need for continued substance use interventions geared toward this high-risk population.
调查受物质使用后果影响最大的人群中的物质使用趋势尤为重要。男男性行为者（MSM）表现出的冰毒和其他物质使用的比率超过了美国其他人群中观察到的比率。这种物质使用与许多负面的健康后果有关。
一项外展计划于 2008 年 1 月 1 日至 2011 年 12 月 31 日与 5599 名独特的有物质使用的男男性行为者进行街头接触，以收集关于自我报告的社会人口统计学和最近物质使用的数据。数据被汇总成六个月的队列，以比较随着时间的推移最近物质使用模式的变化。
参与者平均年龄为 33 岁（SD=8），大多数是白种人/白人（47%）或西班牙裔/拉丁裔（32%），自我报告的 HIV 血清阳性率为 13.4%。在所有队列中，报告的酒精使用（范围=91-93%）、大麻使用（范围=36-46%）和/或冰毒使用（范围=23-27%）很常见；虽然使用亚硝酸戊酯（最高=14%）、摇头丸（最高=12%）、粉末可卡因（最高=8%）和/或快克可卡因（最高=4%）的比例较低，但仍高于美国普通人群。
在有物质使用的 MSM 中，冰毒和其他物质使用仍然很常见，这表明需要继续针对这一高危人群进行物质使用干预。
