Which type of drug is classified as having no medical purpose?

Recreational drugs are substances that are primarily used for pleasure rather than for medicinal purposes. These drugs are often consumed for their psychoactive effects, which can alter mood, consciousness, or perception. Unlike prescription drugs and over-the-counter drugs, which are developed and regulated for specific medical uses and efficacy, recreational drugs do not have an accepted therapeutic application within the medical community.

Additionally, while some performance-enhancing drugs may have legitimate medical applications in certain contexts, their misuse for non-medical enhancement purposes puts them in a complicated category. Therefore, the defining characteristic of recreational drugs is their lack of recognized medical purpose, making them distinct from the other types of drugs mentioned.
