What does the term 'skin popping' refer to in drug administration?

The term 'skin popping' specifically refers to the method of subcutaneous injection of drugs. This practice involves injecting substances just beneath the skin rather than directly into the bloodstream. Skin popping is often seen with the use of certain drugs, particularly opioids, where users may choose this route to avoid the risks associated with intravenous use, such as collapsed veins or infections.

This method can lead to localized skin reactions like abscesses or other complications due to the delivery of substances that may not be intended for subcutaneous use. Despite the risks, individuals may use this method for various reasons, including the belief that it is safer than injecting directly into veins.

While the other methods of drug administration mentioned—such as intravenous use, oral ingestion, and topical application—serve different pharmacological purposes and have unique effects, they do not align with the specific definition of 'skin popping.'
