Cannabis is a genus of flowering plants in the family Cannabaceae. The number of species within the genus is disputed. Three species may be recognized: Cannabis sativa, Cannabis indica, and Cannabis ruderalis; C. ruderalis may be included within C. sativa; all three may be treated as subspecies of a single species, C. sativa; or C. sativa may be accepted as a single undivided species. The genus is widely accepted as being indigenous to and originating from Asia.
Hemp, or industrial hemp, is a botanical class of Cannabis sativa cultivars grown specifically for industrial or medicinal use. It can be used to make a wide range of products. Along with bamboo, hemp is among the fastest growing plants on Earth. It was also one of the first plants to be spun into usable fiber 50,000 years ago. It can be refined into a variety of commercial items, including paper, rope, textiles, clothing, biodegradable plastics, paint, insulation, biofuel, food, and animal feed.
Cannabis sativa is an annual herbaceous flowering plant indigenous to Eastern Asia, but now of cosmopolitan distribution due to widespread cultivation. It has been cultivated throughout recorded history, used as a source of industrial fiber, seed oil, food, recreation, religious and spiritual moods and medicine. Each part of the plant is harvested differently, depending on the purpose of its use. The species was first classified by Carl Linnaeus in 1753. The word sativa means "things that are cultivated."

Marijuana, or marihuana, is a name for the cannabis plant and more specifically a drug preparation from it. "Marijuana" as a term varies in usage, definition and legal application around the world. Some jurisdictions define "marijuana" as the whole cannabis plant or any part of it, while others refer to "marijuana" as a portion of the cannabis plant that contains high levels of tetrahydrocannabinol (THC). Some jurisdictions recognize "marijuana" as a distinctive strain of cannabis, the other being hemp. For legal, research and statistical reference, "marijuana" generally refers to only the dried leaves and flowering tops, with by-products such as hashish or hash oil being uniquely defined and regulated. The form "marihuana" is first attested in Mexican Spanish; it then spread to other varieties of Spanish and to English, French, and other languages.

The history of medicinal cannabis goes back to the ancient times. Ancient physicians in many parts of the world mixed cannabis into medicines to treat pain and other ailments. In the 19th century, cannabis was introduced for therapeutic use in Western Medicine. Since then, there have been several advancements in how the drug is administered. Initially, cannabis was reduced to a powder and mixed with wine for administration. In the 1970s, synthetic THC was created to be administered as the drug Marinol in a capsule. However, the main mode of administration for cannabis is smoking because its effects are almost immediate when the smoke is inhaled. Between 1996 and 1999, eight U.S. states supported cannabis prescriptions opposing policies of the federal government. Most people who are prescribed marijuana for medical purposes use it to alleviate severe pain.
