Cannabis in the context of "Cannabinoid"

Hemp, or industrial hemp, is a plant in the botanical class of Cannabis sativa cultivars grown specifically for industrial and consumable 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.

Although chemotype I cannabis and hemp (types II, III, IV, V) are both Cannabis sativa and contain the psychoactive component tetrahydrocannabinol (THC), they represent distinct cultivar groups, typically with unique phytochemical compositions and uses. Hemp typically has lower concentrations of total THC and may have higher concentrations of cannabidiol (CBD), which potentially mitigates the psychoactive effects of THC. The legality of hemp varies widely among countries. Some governments regulate the concentration of THC and permit only hemp that is bred with an especially low THC content into commercial production.

The Hochdorf Chieftain's Grave is a richly-furnished Celtic burial chamber near Hochdorf an der Enz (municipality of Eberdingen) in Baden-Württemberg, Germany, dating from 530 BC in the Hallstatt culture period. It was discovered in 1968 by an amateur archaeologist and excavated from 1978 to 1979 by the State Historical site office known as the Baden-Württemberg Landesdenkmalamt under the direction of German archeologist Jörg Biel with association from excavation technician Fritz Maurer. By then, the burial mound covering the grave, originally 6 m (20 ft) in height and about 60 m (200 ft) in diameter, had shrunk to about 1 m (3 ft 3 in) in height and was hardly discernible due to centuries of erosion and agricultural use.

A man, roughly 50 years of age and 180 cm (71 in) tall, was laid out on an exceptionally richly decorated 275 cm (108 in) bronze recliner with eight wheels inside the burial chamber. Judging by other objects found there, this man probably had been a Celtic chieftain: He had been buried with a gold-plated torc on his neck, a bracelet on his right arm, a hat made of birch bark, a gold-plated dagger made of bronze and iron, rich clothing, amber jewelry, a razor knife, a nail clipper, a comb, fishing hooks, arrows, and most notably, thin embossed gold plaques which were on his now-disintegrated shoes. At the foot of the couch was a large cauldron decorated with three lions around the brim, originally imported from Magna Graecia but subsequently altered. This cauldron was originally filled with about 400 L (88 imp gal; 110 US gal) of mead. Hemp or cannabis was also found in the Hochdorf grave. The east side of the tomb contained an iron-plated wooden four-wheeled wagon holding a set of bronze dishes—along with the drinking horns found on the walls enough to serve nine people. The whole burial chamber was lined with elaborate textiles.

Plantations are farms specializing in cash crops, usually mainly planting a single crop, with perhaps ancillary areas for vegetables for eating and so on. Plantations, centered on a plantation house, grow crops including cotton, cannabis, tobacco, coffee, tea, cocoa, sugar cane, opium, sisal, oil seeds, oil palms, fruits, rubber trees and forest trees. Protectionist policies and natural comparative advantage have sometimes contributed to determining where plantations are located.

In modern use, the term usually refers only to large-scale estates. Before about 1860, it was the usual term for a farm of any size in the southern parts of British North America, with, as Noah Webster noted, "farm" becoming the usual term from about Maryland northward. The enslavement of people was the norm in Maryland and states southward. The plantations there were forced-labor farms. The term "plantation" was used in most British colonies but very rarely in the United Kingdom itself in this sense. There it was used mainly for tree plantations, areas artificially planted with trees, whether purely for commercial forestry, or partly for ornamental effect in gardens and parks, when it might also cover plantings of garden shrubs.

Smoking is a human behavior which involves the combustion of a substance, usually plant material, and the inhalation of resulting fumes. Today smoking is mostly practiced by rolling the dried leaves of the tobacco plant into a cigarette. Other forms of tobacco smoking include the use of a smoking tobacco with a pipe or cigar, or using a bong. Cigarette smokers almost always inhale the smoke; most pipe and cigar smokers do not inhale.

Smoking is primarily practiced as a route of administration for psychoactive chemicals because the active substances within the burnt, dried plant leaves (or other chemical) can vaporize into a gaseous state and be delivered into the respiratory tract, where they are rapidly absorbed into the bloodstream through the lungs and can reach the central nervous system. In the case of tobacco smoking, these active substances are a mixture of aerosol particles that include the pharmacologically active alkaloid nicotine, which stimulates the nicotinic acetylcholine receptors in the brain, and other non-psychoactive chemicals that result from combustion. Other notable drugs inhaled via smoking include tetrahydrocannabinol (from cannabis), morphine (from opium) cocaine (from crack), and methamphetamine. Designer drugs, or "research chemicals", can also be smoked.

Cannabis (/ˈkænəbɪs/), commonly known as marijuana (/ˌmærəˈwɑːnə/), weed, pot, and ganja, among other names, is a non-chemically uniform psychoactive drug from the Cannabis plant. Native to Central or South Asia, cannabis has been used as a drug for both recreational and entheogenic purposes and in various traditional medicines for centuries. Tetrahydrocannabinol (THC) is the main psychoactive component of cannabis, which is one of the 483 known compounds in the plant, including at least 65 other cannabinoids, such as cannabidiol (CBD). Cannabis can be used by smoking, vaporizing, within food, or as an extract.

Cannabis has various mental and physical effects, which include euphoria, altered states of mind and sense of time, difficulty concentrating, impaired short-term memory, impaired body movement (balance and fine psychomotor control), relaxation, and an increase in appetite. Onset of effects is felt within minutes when smoked, but may take up to 90 minutes when eaten (as orally consumed drugs must be digested and absorbed). The effects last for two to six hours, depending on the amount used. At high doses, mental effects can include anxiety, delusions (including ideas of reference), hallucinations, panic, paranoia, and psychosis. There is a strong relation between cannabis use and the risk of psychosis, though the direction of causality is debated. Physical effects include increased heart rate, difficulty breathing, nausea, and behavioral problems in children whose mothers used cannabis during pregnancy; short-term side effects may also include dry mouth and red eyes. Long-term adverse effects may include addiction, decreased mental ability in those who started regular use as adolescents, heart disease, chronic coughing, susceptibility to respiratory infections, and cannabinoid hyperemesis syndrome.

Drug liberalization is a drug policy process of decriminalizing, legalizing, or repealing laws that prohibit the production, possession, sale, or use of prohibited drugs. Variations of drug liberalization include drug legalization, drug relegalization, and drug decriminalization. Proponents of drug liberalization may favor a regulatory regime for the production, marketing, and distribution of some or all currently illegal drugs in a manner analogous to that for alcohol, caffeine and tobacco.

Proponents of drug liberalization argue that the legalization of drugs would eradicate the illegal drug market and reduce the law enforcement costs and incarceration rates. They frequently argue that prohibition of recreational drugs—such as cannabis, opioids, cocaine, amphetamines and hallucinogens—has been ineffective and counterproductive and that substance use is better responded to by implementing practices for harm reduction and increasing the availability of addiction treatment. Additionally, they argue that relative harm should be taken into account in the regulation of drugs. For instance, they may argue that addictive or dependence-forming substances such as alcohol, tobacco and caffeine have been a traditional part of many cultures for centuries and remain legal in most countries, although other drugs which cause less harm than alcohol, caffeine or tobacco are entirely prohibited, with possession punishable with severe criminal penalties.

Hashish (/həˈʃiːʃ/ ; from Arabic ḥašiš حشيش 'hay'), usually abbreviated as hash, is a compressed form of resin (trichomes) derived from the Cannabis flowers. As a psychoactive substance, it is consumed plain or mixed with tobacco. It has a long history of use in countries such as Afghanistan, India, Pakistan, Iran, Iraq, Lebanon, Morocco, Nepal and Egypt.

Hashish consumption is also popular in Europe. In the United States, dried flowers or concentrates are more popular, and hash has seen a relative decrease in popularity following changes in laws that have indirectly allowed for the development and increased availability of cannabis extracts that are more potent than traditional hashish, although regional differences in product preferences exist. Like many recreational drugs, multiple synonyms and alternative names for hashish exist, and vary greatly depending on the country and native language.

Tetrahydrocannabinol (THC) is a cannabinoid found in cannabis. It is the principal psychoactive constituent of Cannabis and one of at least 113 total cannabinoids identified on the plant. Although the chemical formula for THC (C₂₁H₃₀O₂) describes multiple isomers, the term THC usually refers to the delta-9-THC isomer with chemical name (−)-trans-Δ-tetrahydrocannabinol. It is a colorless oil.

THC, also known pharmaceutically as dronabinol, is used medically to relieve chemotherapy-induced nausea, HIV/AIDS-related anorexia, and symptoms of multiple sclerosis, including neuropathic pain and spasticity. It acts as a partial agonist at CB₁ and CB₂ cannabinoid receptors.
