Injecting Drug Use and HIV Transmission

Sharing injection needles, syringes, etc. with an HIV-infected person can put HIV directly into the user's bloodstream and is the behavior, which most efficiently transmits HIV, as well as HBV and HCV.

Indirect sharing occurs when drug injectors share injection paraphernalia and/or divide a shared or jointly purchased drug while preparing and injecting it. The paraphernalia that carries the potential for transmission are the syringe, needle, "cooker", cotton, and/or rinse water. Sharing these items (sometimes called "works") may transmit HIV or other bacteria and viruses.

Examples of indirect sharing:

  • Squirting the drug back (from a dirty syringe) into the drug cooker and/or someone else's syringe; and
  • Sharing a common filter and/or rinse water.
