Recreational drugs use is the use of psychoactive substances to have fun, for the experience, or to enhance an already positive experience. National laws prohibit the use of many different recreational drugs and medicinal drugs that have the potential for recreational use are heavily regulated. Many other recreational drugs on the other hand are legal, widely culturally accepted, and at the most have an age restriction on using and/or purchasing them. These include alcohol, tobacco, betel nut, and caffeine products.
Recreational drug use is the use of psychoactive drugs for recreational purposes rather than for work, approved medical or spiritual purposes, although the distinction is not always clear (often spiritual use is considered recreational). Since more forms of recreational drug use are being discovered to be self-medication, including using opioids sourced from illicit or other channels for pain-relief and pain-related problems as well as depression, social phobia and other recognised disorders, terms such as "unsupervised drug use", "non-, semi-, and sub-therapeutic drug use", and "allotherapeutic drug use" may be more exact terms to cover the range of activities under discussion. Also since not all nonsupervised drug use is illegal or illicit, these two terms are subsets and often misused.

Psychopharmacologist Ronald K. Siegel refers to intoxication as the "fourth drive," arguing that the human instinct to seek mind-altering substances has so much force and persistence that it functions like the human desire to satisfy hunger, thirst and the need for shelter.
