Purposes

Image
Psychoactive substances are used by humans for a number of different purposes to achieve a specific end. These uses vary widely between cultures. Some substances may have controlled or illegal uses while others may have shamanic purposes, and still others are used medicinally. Other examples would be social drinking, nootropic, or sleep aids. Caffeine is the world's most widely consumed psychoactive substance, but unlike many others, it is legal and unregulated in nearly all jurisdictions. In North America, 90% of adults consume caffeine daily. Psychoactive drugs are divided into different groups according to their pharmacological effects.

History

Psychoactive drug use can be traced to prehistory. There is archaeological evidence of the use of psychoactive substances (mostly plants) dating back at least 10,000 years, and historical evidence of cultural use over the past 5,000 years. The chewing of coca leaves, for example, dates back over 8,000 years ago in Peruvian society. Medicinal use is one important facet of psychoactive drug usage. However, some have postulated that the urge to alter one's consciousness is as primary as the drive to satiate thirst, hunger or sexual desire. Supporters of this belief contend that the history of drug use and even children's desire for spinning, swinging, or sliding indicate that the drive to alter one's state of mind is universal. One of the first people to articulate this point of view, set aside from a medicinal context, was American author Fitz Hugh Ludlow (1836–1870) in his book The Hasheesh Eater (1857): Drugs are able to bring humans into the neighborhood of divine experi...

Determinants of effects

The theory of dosage, set, and setting is a useful model in dealing with the effects of psychoactive substances, especially in a controlled therapeutic setting as well as in recreational use. Dr. Timothy Leary, based on his own experiences and systematic observations on psychedelics, developed this theory along with his colleagues Ralph Metzner, and Richard Alpert (Ram Dass) in the 1960s. Dosage The first factor, dosage, has been a truism since ancient times, or at least since Paracelsus who said, "Dose makes the poison." Some compounds are beneficial or pleasurable when consumed in small amounts, but harmful, deadly, or evoke discomfort in higher doses. Set The set is the internal attitudes and constitution of the person, including their expectations, wishes, fears, and sensitivity to the drug. This factor is especially important for the hallucinogens, which have the ability to make conscious experiences out of the unconscious. In traditional cultures, set is shaped primaril...
