  1. Injection

    An injection is an infusion method of putting fluid into the body, usually with a syringe and a hollow needle which is pierced through the skin to a sufficient depth for the material to be administered into the body. An injection follows a parenteral route of administration; that is, administration via a route other than through the digestive tract. There are several methods of injection or infusion, including intradermal, subcutaneous, intramuscular, intravenous, intraosseous, and intraperitoneal. Long-acting forms of subcutaneous/intramuscular injections are available for various drugs, and are called depot injections. Injections are among the most common health care procedures, with at least 16 billion administered in developing and transitional countries each year. 95% of injections are administered in curative care, 3% are for immunization, and the rest for other purposes, such as blood transfusions.

Drug-related overdose deaths began to spoke in 2015 with the presence of fetanyl, according to Philadelphia Public Health. ( Fox News) The sites would give drug addicts a safe haven to shoot up and would offer sterile injection equipment, including needles, and Naloxone. Fox News would also give referrals to treatment centers, social services clinics and wound care facilities.
