History of Cannabis. For centuries, in China and Asia, cannabis has been widely used for its healing properties. It has been used for thousands of years for medicine and food. Historical records suggest that ancient cultures in Asia, Africa, and Europe, among others, utilized the plant for treating a wide range of ailments, including pain relief, inflammation reduction, and anxiety management. It has been a scientific interest for centuries, debating whether it is medically safe or should be classified as an illegal substance. That is, until newfound scientific proof showed that the plant indeed has medical values and may have a place in modern society.

In fact, cannabis was listed in the United States Pharmacopeia, a compendium of drugs published from 1820 until 1942, as a recognized medicine for various ailments. However, its use became even more widespread in the 20th century for religious, spiritual, medicinal, and recreational purposes. It was during this time that its possession, use, and sale became prohibited.
