Implementation of harm reduction toward crack users in Brazil: barriers and achievements.

From 2002 to 2005, we evaluated five Brazilian harm reduction programs ran by active drug users who distributed pipes, condoms, educational material, and provided referral to crack users. System-wide barriers identified: funds discontinuation and legislation barriers toward fieldwork. Major achievements: increased access to health, social, and psychological support. Crack-cocaine users experience a plethora of health/social problems, attenuated by low-threshold and user-friendly interventions, particularly those developed by other drug users. However, a stronger political commitment is needed to face a fast growing crack-cocaine epidemic in Brazil, aiming to ensure availability/continuity of funds, implementation of large-scale interventions, outreach workers training, and proper evaluation.
