Detailed Description:

Low levels of zinc are associated with an increased risk of HIV-related death and opportunistic infections in HIV infected individuals. Drug users are especially susceptible to zinc deficiency. The purpose of this trial is to evaluate the effectiveness of zinc therapy in preventing immune failure in HIV infected individuals who abuse drugs.

This trial will last 30 months. Participants will be randomly assigned to receive either zinc supplements or placebo. Male participants will receive 15 mg of zinc and female participants will receive 12 mg of zinc. Clinical and laboratory study visits will occur at 3 or 6 month intervals throughout the study.
