Marijuana
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 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. The effects last for two to six hours, depending on the amoun ...

Effects Of Cannabis
The effects of cannabis are caused by chemical compounds in the cannabis plant, including 113 different cannabinoids such as tetrahydrocannabinol (THC) and 120 terpenes, which allow its drug to have various psychological and physiological effects on the human body. Different plants of the genus Cannabis contain different and often unpredictable concentrations of THC and other cannabinoids and hundreds of other molecules that have a pharmacological effect, so that the final net effect cannot reliably be foreseen. Acute effects while under the influence can sometimes include euphoria. Although some assert that cannabidiol (CBD), another cannabinoid found in cannabis in varying amounts, may alleviate the adverse effects of THC that some users experience, little is known about CBD effects on humans. Cannabinoid receptor antagonists have previously been tested as antidotes for cannabis intoxication with success, reducing or eliminating the physiological and psychological effects of ...

Cannabis And Memory
The long-term effects of cannabis have been the subject of ongoing debate. Because cannabis is illegal in most countries, clinical research presents a challenge and there is limited evidence from which to draw conclusions. In 2017, the U.S. National Academies of Sciences, Engineering, and Medicine issued a report summarizing much of the published literature on health effects of cannabis, into categories regarded as conclusive, substantial, moderate, limited and of no or insufficient evidence to support an association with a particular outcome. Dependency Cannabis is the most widely used illicit drug in the Western world. In the United States, 10-20% of those who begin the use of cannabis daily will later become dependent. Cannabis use can lead to addiction, which is defined as "when the person cannot stop using the drug even though it interferes with many aspects of his or her life." Cannabis use disorder is defined in the fifth revision of the '' Diagnostic and Statistical Man ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Names For Cannabis
''Cannabis ''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''. Alternative ...'' has many different names, including more than 1,200 slang terms, and more than 2,300 names for individual strains. Additionally, there are many names to describe the state of being under the influence of the substance. This list is not exhaustive; it includes well-attested names. The first recorded name for cannabis is the Chinese 麻 (Má), which is prehistoric. Formal names Strains, cultivation and preparation Commercial cannabis growers and retailers have given individual strains more than 2,300 names.

Cannabidiol
Cannabidiol (CBD) is a phytocannabinoid discovered in 1940. It is one of 113 identified cannabinoids in cannabis plants, along with tetrahydrocannabinol (THC), and accounts for up to 40% of the plant's extract. , clinical research on CBD included studies related to anxiety, cognition, movement disorders, and pain, but there is insufficient high-quality evidence that cannabidiol is effective for these conditions. Nevertheless, CBD is an herbal dietary supplement promoted with unproven claims of particular therapeutic effects. The global market size for CBD was predicted to exceed billion by 2028. Cannabidiol can be taken internally in multiple ways, including by inhaling cannabis smoke or vapor, oral, and as an aerosol spray into the cheek. It may be supplied as CBD oil containing only CBD as the active ingredient (excluding tetrahydrocannabinol HCor terpenes), CBD-dominant hemp extract oil, capsules, dried cannabis, or prescription liquid solution. CBD does not have th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cannabis Edible
A cannabis edible, also known as a cannabis-infused food or simply an edible, is a food product (either homemade or produced commercially) that contains decarboxylated cannabinoids (cannabinoid acids converted to their orally bioactive form) from cannabis extract as an active ingredient. Although ''edible'' may refer to either a food or a drink, a cannabis-infused drink may be referred to more specifically as a liquid edible or drinkable. Edibles are a way to consume cannabis. Unlike smoking, in which cannabinoids are inhaled into the lungs and pass rapidly into the bloodstream, peaking in about ten minutes and wearing off in a couple of hours, cannabis edibles may take hours to digest, and their effects may peak two to three hours after consumption and persist for around six hours. The food or drink used may affect both the timing and potency of the dose ingested. Most edibles contain a significant amount of THC, which can induce a wide range of effects, including: heighte ...

Cannabis
''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. The plant is also known as hemp, although this term is often used to refer only to varieties of ''Cannabis'' cultivated for non-drug use. Cannabis has long been used for hemp fibre, hemp seeds and their oils, hemp leaves for use as vegetables and as juice, medicinal purposes, and as a recreational drug. Industrial hemp products are made from cannabis plants selected to produce an abundance of fibre. Various cannabis strains have been bred, often selecti ...

Cannabis Smoking
Cannabis smoking (or colloquially smoking pot) is the inhalation of smoke or vapor released by heating the flowers, leaves, or extracts of cannabis and releasing the main psychoactive chemical, Δ9-tetrahydrocannabinol (THC), which is absorbed into the bloodstream via the lungs. Archaeological evidence indicates cannabis with high levels of THC was being smoked at least 2,500 years ago. In addition to being smoked and vaporized, cannabis and its active cannabinoids may be ingested, placed under the tongue, or applied to the skin. The bioavailability characteristics and effects of smoking and vaporizing cannabis differ from other cannabis consumption methods in having a more rapid and predictable onset of effect. Methods Cannabis (marijuana) can be smoked in a variety of pipe-like implements made in different shapes and of different materials including hand pipes ( "bowls"), water pipes ("bongs"), cigarettes ("joints"), or blunts. Solar puffing (also called ''sola ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cannabinoid
Cannabinoids () are several structural classes of compounds found in the cannabis plant primarily and most animal organisms (although insects lack such receptors) or as synthetic compounds. The most notable cannabinoid is the phytocannabinoid tetrahydrocannabinol (THC) (delta-9-THC), the primary intoxicating compound in cannabis. Cannabidiol (CBD) is a major constituent of temperate Cannabis plants and a minor constituent in tropical varieties. At least 113 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 ami ...

Recreational Marijuana
Recreational drug use indicates the use of one or more psychoactive drugs to induce an altered state of consciousness either for pleasure or for some other casual purpose or pastime by modifying the perceptions and emotions of the user. When a psychoactive drug enters the user's body, it induces an intoxicating effect. Generally, recreational drugs are divided into three categories: depressants (drugs that induce a feeling of relaxation and calmness); stimulants (drugs that induce a sense of energy and alertness); and hallucinogens (drugs that induce perceptual distortions such as hallucination). In popular practice, recreational drug use generally is a tolerated social behaviour, rather than perceived as the medical condition of self-medication. However, heavy use of some drugs is socially stigmatized. Many people also use prescribed and controlled depressants such as opioids, as well as opiates and benzodiazepines. Common recreational drugs include caffeine, commonly found ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Entheogenic Use Of Cannabis
Cannabis has served as an entheogen—a chemical substance used in religious or spiritual contexts—in the Indian subcontinent since the Vedic period dating back to approximately 1500 BCE, but perhaps as far back as 2000 BCE. It was introduced to the New World by the Spaniards in 1530-45. Cannabis has been used by shamanic and pagan cultures to ponder deeply religious and philosophical subjects related to their tribe or society, to achieve a form of enlightenment, to unravel unknown facts and realms of the human mind and subconscious, and also as an aphrodisiac during rituals or orgies. There are several references in Greek mythology to a powerful drug that eliminated anguish and sorrow. Herodotus wrote about early ceremonial practices by the Scythians, thought to have occurred from the 5th to 2nd century BCE. Itinerant Hindu saints have used it in the Indian subcontinent for centuries. Mexican-Indian communities occasionally use cannabis in religious ceremonies by leaving bun ...

Cannabis Indica
''Cannabis indica'' is an annual plant species in the family Cannabaceae which produces large amounts of tetrahydrocannabinol (THC) and is cultivated for purposes including hashish in India. The high concentrations of THC provide euphoric effects making it popular for use both as a recreational drug, alternative medicine, and a clinical research drug. 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. Richard Evans Schultes described ''C. indica'' as relatively short, conical, and densely branched, whereas '' C. sativa'' was described as tall and laxly branched. Loran C. Anderson described ''C. indica'' plants as having short, broad leaflets whereas those of ''C. sativa'' were characterized as relatively long and narrow. ''C. indica'' plants conforming to Schultes's and Ande ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tetrahydrocannabinol
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 lipid found in cannabis and, like most pharmacologically active secondary metabolites of plants, it is assumed to be involved in the plant's evolutionary adaptation, putatively 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, coordi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
