Injection is a method of introducing a substance into the body using a needle and syringe. This can be done for various purposes, including medical treatment, administration of vaccines, or recreational drug use. In medicine, injections are a common way to deliver medications that would otherwise be broken down by the digestive system or could not be absorbed effectively by other routes. The type of injection depends on the medication, the desired speed of absorption, and the specific area of the body.

Common types of injections include intramuscular (into a muscle), subcutaneous (into the fatty tissue just under the skin), and intravenous (directly into a vein). Intravenous injections provide the fastest delivery of medication to the bloodstream. Intramuscular injections allow for a more gradual release of medication, while subcutaneous injections offer the slowest absorption rate. The needle size and length vary depending on the injection type and the substance being administered. Proper technique is crucial to minimize discomfort and prevent complications.

Beyond medical applications, injection is also associated with the non-medical use of drugs, often via intravenous administration. This practice carries significant health risks, including the transmission of infectious diseases like HIV and hepatitis if needles are shared, as well as the potential for overdose and localized infections at the injection site. Due to these risks, sterile equipment and safe practices are paramount when injections are medically necessary.
