Researchers at the University of Illinois at Chicago are recruiting adults ages 21-55 to find out how cocaine affects brain functioning in men and women with HIV. Participants will complete tests of memory, attention and other abilities, and complete an MRI brain Scan.
• Individuals who have or have not used cocaine regularly in the past 2 years
• No other significant drug use history
• Age 21 to 55
• Must have no metal in your body
Participants will be compensated for their time on both the Screening and Scanning visits.
