Cocaine use and risky injection and sexual behaviors

The association between cocaine use (crack and injection cocaine) and risky behaviors for human immunodeficiency virus (HIV) infection was investigated among participants in a multi-site study at drug treatment and non-drug treatment sites in Worcester, Massachusetts. Cocaine use was more prevalent among young, African-American men. Compared to heroin injectors cocaine injectors had higher risk injection and sexual behaviors. Among non-injectors, crack users were more likely to have multiple partners and receive money or drugs for sex. Cocaine use, either injected or smoked as crack, should be considered a high risk behavior for HIV infection.
