Association of Injection Practices and Overdose With Drug Use Typologies: A Latent Class Analysis Among People Who Inject Drugs in Baltimore, 2017.

ABSTRACT: Increasing overdose mortality and new HIV outbreaks in the U.S. highlight the need to identify risk behavior profiles among people who inject drugs (PWID).
