RESUMO
We studied the motivations behind supply and demand of antiretroviral drugs (ARVs) in the illicit street markets of the metropolitan statistical area of Atlanta, Sandy Springs, and Roswell, Georgia. We found that these two market actions were largely interdependent: 39.53% of participants said that they sold their ARVs to pay for personal needs, and 20.93% said that they bought ARVs because they had previously sold them to pay for personal needs. The pattern that emerged suggests that illicit street markets have become mechanisms through which HIV patients cooperate to achieve competing goals: cover personal needs and keep up, however imperfectly, with their medication regime. We also found that HIV patients used illicit street markets because they faced institutional deficiencies, such as exclusion from the Ryan White/ADAP program, long waiting times to see a doctor, and prescription delays.
