Cannabis
''Cannabis'' () is a genus of flowering plants in the family Cannabaceae that is widely accepted as being indigenous to and originating from the continent of Asia. However, the number of species is disputed, with as many as three species being recognized: '' Cannabis sativa'', '' C. indica'', and '' C. ruderalis''. Alternatively, ''C. ruderalis'' may be included within ''C. sativa'', or all three may be treated as subspecies of ''C. sativa'', or ''C. sativa'' may be accepted as a single undivided species. The plant is also known as hemp, although this term is usually used to refer only to varieties cultivated for non-drug use. Hemp has long been used for fibre, seeds and their oils, leaves for use as vegetables, and juice. Industrial hemp textile products are made from cannabis plants selected to produce an abundance of fibre. ''Cannabis'' also has a long history of being used for medicinal purposes, and as a recreational drug known by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cannabis (drug)
Cannabis (), commonly known as marijuana (), weed, pot, and ganja, List of slang names for cannabis, 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 use of cannabis, 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 Cannabis smoking, by smoking, Vaporizer (inhalation device), vaporizing, Cannabis edible, within food, or Tincture of cannabis, as an extract. Cannabis has effects of cannabis, various mental and physical effects, which include euphoria, altered states of mind and Cannabis and time perception, sense of time, difficulty concentrating, Cannabis and memory, impaired short-term memo ...

Cannabis Sativa
''Cannabis sativa'' is an annual Herbaceous plant, herbaceous flowering plant. The species was first classified by Carl Linnaeus in 1753. The specific epithet ''Sativum, sativa'' means 'cultivated'. Indigenous to East Asia, Eastern Asia, the plant is now of cosmopolitan distribution due to widespread cultivation. It has been cultivated throughout recorded history and used as a source of Hemp#fibre, industrial fiber, Hemp oil, seed oil, Hempnut, food, and Medical cannabis, medicine. It is also used as Cannabis (drug), a recreational drug and for entheogenic use of cannabis, religious and spiritual purposes. Description The flowers of ''Cannabis sativa'' plants are most often either male or female, but only plants displaying female pistils can be or turn hermaphrodite. Males can never become hermaphrodites. It is a short-day flowering plant, with staminate (male) plants usually taller and less robust than pistillate (female or male) plants. The flowers of the female plant are arr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medical Cannabis
Medical cannabis, medicinal cannabis or medical marijuana (MMJ) refers to cannabis products and cannabinoid molecules that are prescribed by physicians for their patients. The use of cannabis as medicine has a long history, but has not been as rigorously tested as other medicinal plants due to legal and governmental restrictions, resulting in limited clinical research to define the safety and efficacy of using cannabis to treat diseases. Preliminary evidence has indicated that cannabis might reduce nausea and vomiting during chemotherapy and reduce chronic pain and muscle spasms. Regarding non-inhaled cannabis or cannabinoids, a 2021 review found that it provided little relief against chronic pain and sleep disturbance, and caused several transient adverse effects, such as cognitive impairment, nausea, and drowsiness. Short-term use increases the risk of minor and major adverse effects. Common side effects include dizziness, feeling tired, vomiting, and hallucination ...

Cannabis Strain
''Cannabis'' strains is a popular name to refer to plant varieties of the monospecific genus ''Cannabis sativa'' L.. They are either pure or hybrid varieties of the plant, which encompasses various sub-species '' C. sativa'', '' C. indica'', and '' C. ruderalis''. Varieties are developed to intensify specific characteristics of the plant, or to differentiate the strain for the purposes of marketing or to make it more effective as a drug. Variety names are typically chosen by their growers, and often reflect properties of the plant such as taste, color, smell, or the origin of the variety. The ''Cannabis'' strains referred to in this article are primarily those varieties with recreational and medicinal use. These varieties have been cultivated to contain a high percentage of cannabinoids. Several varieties of ''cannabis'', known as hemp, have a very low cannabinoid content, and are instead grown for their fiber and seed. Due to the legal status of the plant in many jurisdict ...

Cannabis Cultivation
Cultivation of cannabis is the production of cannabis infructescences ("buds" or "leaves"). Cultivation techniques for other purposes (such as hemp production) differ. In the United States, all cannabis products in a regulated market must be grown in the state where they are sold because federal law continues to ban interstate cannabis sales. Most regulated cannabis is grown indoors.Byrne, Genevieve (March 15, 2023). "Energy and Equity in Cannabis Cultivation" (PDF). ''Institute for Energy and the Environment, Vermont Law and Graduate School''. Retrieved April 27, 2023. Occupational disease, Occupational diseases, including asthma, are an emerging concern in the rapidly expanding U.S. cannabis industry. Cannabis cultivation and processing technicians may be exposed to numerous respiratory hazards, e.g. organic particulate matter and dust from ground cannabis flower, mold, bacterial endotoxins, and pesticides. Employees exposed to ground cannabis without adequate controls are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cannabidiol
Cannabidiol (CBD) is a phytocannabinoid, one of 113 identified cannabinoids in ''Cannabis'', along with tetrahydrocannabinol (THC), and accounts for up to 40% of the plant's extract. Medically, it is an anticonvulsant used to treat multiple forms of epilepsy. It was discovered in 1940 and, as of 2024 clinical research on CBD included studies related to the treatment of anxiety, addiction, psychosis, movement disorders, and pain, but there is insufficient evidence-based medicine, high-quality evidence that CBD is effective for these conditions. CBD is sold as an herbal dietary supplement and promoted with yet unproven claims of particular therapeutic effects. Cannabidiol can be route of administration, taken internally in multiple ways, including by Route of administration#Inhalation, inhaling cannabis cannabis smoking, smoke or vaporizer (inhalation device), vapor, Oral administration, swallowing it by mouth, and through use of an aerosol spray into the buccal administration, ...

Hemp
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, Bioplastic, biodegradable plastics, paint, Thermal insulation, insulation, biofuel, food, and Fodder, 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 phytochemistry, 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 ...

Cannabis Ruderalis
''Cannabis ruderalis'' is a Variety (botany), variety, subspecies, or species of ''Cannabis'' native to Central Europe, Central and Eastern Europe and Russia. It contains a relatively low quantity of psychoactive compound tetrahydrocannabinol (THC) and does not require photoperiod to blossom (unlike ''C. indica'' and ''C. sativa''). Some scholars accept ''C. ruderalis'' as its own species due to its unique traits and phenotypes which distinguish it from ''Cannabis indica, C. indica'' and ''Cannabis sativa, C. sativa''; others debate whether ''ruderalis'' is a subspecies under ''C. sativa''. Description This species is smaller than other species of the genus, rarely growing over in height. The plants have "thin, slightly fibrous stems" with little branching. The foliage is typically open with large leaves. ''C. ruderalis'' reaches maturity much quicker than other species of ''Cannabis,'' typically 5–7 weeks after being planted from seed. Unlike othe ...

Tetrahydrocannabinol
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''-Δ9-tetrahydrocannabinol. It is a colorless oil. Medical uses THC, referred to as dronabinol in the pharmaceutical context, is approved in the United States as a capsule or solution to relieve chemotherapy-induced nausea and vomiting and HIV/AIDS-induced anorexia. THC is an active ingredient in nabiximols, a specific extract of ''Cannabis'' that was approved as a botanical drug in the United Kingdom in 2010 as a mouth spray for people with multiple sclerosis to alleviate neuropathic pain, spasticity, overactive bladder, and other symptoms. Nabiximols (as Sativex) is available as a prescription drug in Canada. In 20 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cannabis Indica
''Cannabis indica'' is an annual plant species in the family Cannabaceae indigenous to the Hindu Kush mountains of Southern Asia. The plant produces large amounts of tetrahydrocannabinol (THC) and tetrahydrocannabivarin (THCV), with total cannabinoid levels being much higher than observed in industrial hemp varieties. It is now widely grown in China, India, Nepal, Thailand, Afghanistan, and Pakistan, as well as southern and western Africa, and is cultivated for purposes including hashish in India. The high concentrations of THC or THCV provide euphoric effects making it popular for use for several purposes, not only simple pleasure but also clinical drug research, potential new drug research, and use in alternative medicine, among many others. Taxonomy In 1785, Jean-Baptiste Lamarck published a description of a second species of ''Cannabis'', which he named ''Cannabis indica''. Lamarck based his description of the newly named species on plant specimens collected in India. R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cannabinoid
Cannabinoids () are several structural classes of compounds found primarily in the ''Cannabis'' plant or as synthetic compounds. The most notable cannabinoid is the phytocannabinoid tetrahydrocannabinol (THC) (delta-9-THC), the primary psychoactive compound in Cannabis (drug), cannabis. Cannabidiol (CBD) is also a major constituent of temperate cannabis plants and a minor constituent in tropical varieties. At least 100 distinct phytocannabinoids have been isolated from cannabis, although only four (i.e., THCA, CBDA, CBCA and their common precursor CBGA) have been demonstrated to have a biogenetic origin. It was reported in 2020 that phytocannabinoids can be found in other plants such as rhododendron, licorice and liverwort, and earlier in Echinacea. Phytocannabinoids are multi-ring phenolic compounds structurally related to THC, but endocannabinoids are fatty acid derivatives. Nonclassical synthetic cannabinoids (cannabimimetics) include aminoalkylindoles, 1,5-diarylpyrazoles, qu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
