An illicit psychoactive substance is characterized by being illegally obtained. This definition encompasses substances that are not approved by legal regulatory authorities for any type of use, whether recreational or medical.

When a substance is classified as illicit, it indicates that its manufacture, distribution, or possession is against the law. Such substances often contribute to various public health concerns and can lead to addiction, criminal behavior, and social issues. The emphasis on illegal acquisition highlights the legal ramifications that accompany the use of these substances, which can include penalties for possession or distribution.

In contrast to illicit substances, those that are approved for recreational use, legally prescribed, or utilized for clinical purposes fall within acceptable legal frameworks. Substances that are approved for recreational use may still have regulations in place, while legally prescribed substances are recognized by health professionals for specific medical conditions, and clinical substances are intended for research or therapeutic use.
