While recreational use, possession and trade of non-medicinal drugs described by the Opium Law are all technically illegal under Dutch law, official policy since the late 20th century has been to openly tolerate all recreational use while tolerating the other two under certain circumstances. This pragmatic approach was motivated by the idea that a drug-free Dutch society is unrealistic and unattainable, and efforts would be better spent trying to minimize harm caused by recreational drug use. As a result of this gedoogbeleid, the Netherlands is typically seen as much more tolerant of drugs than most other countries.
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, C. indica, and C. ruderalis. Alternatively, C. ruderalis may be included within C. sativa, all three may be treated as subspecies of 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.
Tetrahydrocannabinol (THC) 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-Δ9-tetrahydrocannabinol. THC is a terpenoid found in cannabis and, like many pharmacologically active phytochemicals, it is assumed to be involved in the plant's evolutionary adaptation against insect predation, ultraviolet light, and environmental stress. THC was first discovered and isolated by Israeli chemist Raphael Mechoulam in Israel in 1964. It was found that, when smoked, THC is absorbed into the bloodstream and travels to the brain, attaching itself to endocannabinoid receptors located in the cerebral cortex, cerebellum, and basal ganglia. These are the parts of the brain responsible for thinking, memory, pleasure, coordination and movement.
Medical cannabis, or medical marijuana (MMJ), is cannabis and cannabinoids that are prescribed by physicians for their patients. The use of cannabis as medicine has not been rigorously tested due to production and governmental restrictions, resulting in limited clinical research to define the safety and efficacy of using cannabis to treat diseases.
The Single Convention on Narcotic Drugs, 1961 is an international treaty that controls activities of specific narcotic drugs and lays down a system of regulations for their medical and scientific uses; it also establishes the International Narcotics Control Board.
Cannabis, also known as marijuana among other names, is a psychoactive drug from the cannabis plant. Native to Central or South Asia, the cannabis plant 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 flower essential oil, also known as hemp essential oil, is an essential oil obtained by steam distillation from the flowers, panicles, stem, and upper leaves of the hemp plant. Hemp essential oil is distinct from hemp seed oil and hash oil: the former is a vegetable oil that is cold-pressed from the seeds of low-THC varieties of hemp, the latter is a THC-rich extract of dried female hemp flowers (marijuana) or resin (hashish).
In the United States, increased restrictions and labeling of cannabis as a poison began in many states from 1906 onward, and outright prohibitions began in the 1920s. By the mid-1930s cannabis was regulated as a drug in every state, including 35 states that adopted the Uniform State Narcotic Drug Act. The first national regulation was the Marihuana Tax Act of 1937.
The drug policy of Sweden is based on zero tolerance focusing on prevention, treatment, and control, aiming to reduce both the supply of and demand for illegal drugs. The general drug policy is supported by all major Swedish political parties with the exceptions of the Left Party - which advocates for the decriminalization of private consumption - and 5 of the 7 major parties' youth wings.
The Convention on Psychotropic Substances of 1971 is a United Nations treaty designed to control psychoactive drugs such as amphetamine-type stimulants, barbiturates, benzodiazepines, and psychedelics signed in Vienna, Austria on 21 February 1971. The Single Convention on Narcotic Drugs of 1961 did not ban the many newly discovered psychotropics, since its scope was limited to drugs with cannabis, coca and opium-like effects.
Cannabis in Switzerland is illegal, though minor possession was decriminalised to a fine in 2012. Several cantons began to allow adults to cultivate and use cannabis in 2012, but this was struck down by federal courts. In 2016, four cities stated they were looking into establishing pilot cannabis clubs. The number of cannabis users in Switzerland is estimated to be around 500,000 among a population of 8 million.
The International Nonproprietary Name dronabinol, also known under the trade names Marinol, Syndros, Reduvo and Adversa, is a generic name for the molecule of delta-9-tetrahydrocannabinol in the pharmaceutical context. It has indications as an appetite stimulant, antiemetic, and sleep apnea reliever and is approved by the FDA as safe and effective for HIV/AIDS-induced anorexia and chemotherapy-induced nausea and vomiting only.
Cannabis drug testing describes various drug test methodologies for the use of cannabis in medicine, sport, and law. Cannabis use is highly detectable and can be detected by urinalysis, hair analysis, as well as saliva tests for days or weeks.
Cannabis in India has been known to be used at least as early as 2000 BCE. In Indian society, common terms for cannabis preparations include charas (resin), ganja (flower), and bhang, with Indian drinks such as bhang lassi and bhang thandai made from bhang being one of the most common legal uses.
Cannabis has been cultivated in Japan since the Jōmon period of Japanese prehistory approximately six to ten thousand years ago. As one of the earliest cultivated plants in Japan, cannabis hemp was an important source of plant fiber used to produce clothing, cordage, and items for Shinto rituals, among numerous other uses. Hemp remained ubiquitous for its fabric and as a foodstuff for much of Japanese history, before cotton emerged as the country's primary fiber crop amid industrialization during the Meiji period. Following the conclusion of the Second World War and subsequent occupation of Japan, a prohibition on cannabis possession and production was enacted with the passing of the Cannabis Control Law.
In Thailand, cannabis, known by the name Ganja was decriminalised on 9 June 2022. Medical use, with patients requiring a prescription, has been made legal since 2018. Since 2022, the Thai Food and Drug Administration officially removed cannabis plant from the Category 5 narcotics list. Possession, cultivation, distribution, consumption, and sales of all cannabis plant parts are legal. Cannabis extracts and cannabis products containing THC more than 0.2% by weight are still categorised as narcotics. Import and export of cannabis are still highly regulated. Recreational use of cannabis products is discouraged but legal. Sales of cannabis plant parts, products, and edibles are prohibited to minors, pregnant women, and breastfeeding women. Cannabis smoke is considered a public nuisance and thus prohibited in public areas.
The following outline is provided as an overview of and topical guide to the plant Cannabis sativa and its relatives Cannabis indica and Cannabis ruderalis, the drug cannabis (drug) and the industrial product hemp.
Tochigishiro is a cultivar of hemp grown in Tochigi Prefecture, Japan. It meets international standards of non-narcotic agricultural hemp at about 0.2% THC, reckoned "remarkably low" by Sensi Seeds. It was grown in the early 20th century at Arlington Experimental Farm near the United States capital. The modern variety was developed beginning in 1973 by Fukuoka University professor of pharmacy Itsuo Nishioka from seeds "found in southern Japan", and completed c. 1982 by the Tochigi prefectural government at Tochigi Agricultural Experiment Station in Tochigi-shi. According to a National Institute of Mental Health-affiliated researcher, the strain is missing the enzyme tetrahydrocannabinolic acid synthase that makes most Cannabis capable of producing THC. It is the most widely grown cultivar in Japan in the 21st century, being exempt from prohibition under the Cannabis Control Law, due to its low levels of psychoactive chemicals. Approximately 90% of the hemp grown in Japan is the Tochigishiro variety.
The removal of cannabis and cannabis resin from Schedule IV of the Single Convention on narcotic drugs, 1961 is a change in international law that took place in 2021, on the basis of a scientific assessment by the World Health Organization.
