Needle sharing is the practice of intravenous drug-users by which a needle or syringe is shared by multiple individuals to administer intravenous drugs such as heroin, steroids, and hormones. This is a primary vector for blood-borne diseases which can be transmitted through blood (blood-borne pathogens). People who inject drugs (PWID) are at an increased…
