Cannabinol
Cannabinol (CBN) is a mildly psychoactive cannabinoid that acts as a low affinity partial agonist at both CB1 and CB2 receptors. This activity at CB1 and CB2 receptors constitutes interaction of CBN with the endocannabinoid system (ECS). CBN was the first cannabis compound to be isolated from cannabis extract in the late 1800s. Its structure and chemical synthesis were achieved by 1940, followed by some of the first basic research studies to determine the effects of individual cannabis-derived compounds in vivo. Although CBN shares the same mechanism of action as other phytocannabinoids (e.g., delta-9 tetrahydrocannabinol or D9THC), it has a lower affinity for CB1 receptors, meaning that much higher doses of CBN are required in order to experience effects, such as mild sedation. Chemical structure Cannabinoid receptor agonists are categorized into four groups based on chemical structure. CBN, as one of the many phytocannabinoids derived from Cannabis Sativa L, is considered ...

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, coordination a ...

Phytocannabinoids
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 amin ...

11-Hydroxycannabinol
11-Hydroxycannabinol (11-OH-CBN) is the main active metabolite of cannabinol (CBN), one of the active components of cannabis, and has also been isolated from cannabis itself. It is more potent than CBN itself, acting as an agonist of CB1 with around the same potency as THC, but is a weak antagonist at CB2.

11-Hydroxy-THC
11-Hydroxy-Δ9-tetrahydrocannabinol (11-OH-Δ9-THC, alternatively numbered as 7-OH-Δ1-THC), usually referred to as 11-hydroxy-THC, is the main active metabolite of tetrahydrocannabinol (THC), which is formed in the body after THC is consumed. After cannabis consumption, THC is metabolized inside the body by cytochrome P450 enzymes such as CYP2C9 and CYP3A4 into 11-hydroxy-THC and then further metabolized by the dehydrogenase and CYP2C9 enzyme to form 11-nor-9-carboxy-THC (THC-COOH) which is inactive at the CB1 receptors; and further glucuronidated to form 11-nor-delta-9-tetrahydrocannabinol-9-carboxylic acid glucuronide (delta-9-THC-COOH-glu) where it is excreted in both feces and urine. Both compounds, along with THC, can be assayed in drug tests. 11-hydroxy-THC can be formed after consumption of THC from inhalation (vaping, smoking) and oral (by mouth, edible, sublingual) use, although levels of 11-hydroxy-THC are typically higher when eaten compared to inhalation.

Endocannabinoid System
The endocannabinoid system (ECS) is a biological system composed of endocannabinoids, which are endogenous lipid-based retrograde neurotransmitters that bind to cannabinoid receptors (CBRs), and cannabinoid receptor proteins that are expressed throughout the vertebrate central nervous system (including the brain) and peripheral nervous system. The endocannabinoid system remains under preliminary research, but may be involved in regulating physiological and cognitive processes, including fertility, pregnancy, pre- and postnatal development, various activity of immune system, appetite, pain-sensation, mood, and memory, and in mediating the pharmacological effects of cannabis. The ECS plays an important role in multiple aspects of neural functions, including the control of movement and motor coordination, learning and memory, emotion and motivation, addictive-like behavior and pain modulation, among others. Two primary cannabinoid receptors have been identified: CB1, first cl ...

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 selectively to pro ...

Cannabis Sativa
''Cannabis sativa'' is an annual Herbaceous plant, herbaceous flowering plant indigenous to East Asia, Eastern Asia, but now of cosmopolitan distribution due to widespread cultivation. It has been cultivated throughout recorded history, used as a source of Hemp#fibre, industrial fiber, Hemp oil, seed oil, Hempnut, food, Cannabis (drug), recreation, entheogenic use of cannabis, religious and spiritual moods and Medical cannabis, 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 ''Sativum, sativa'' means "things that are cultivated." Plant physiology The flowers of ''Cannabis sativa'' are unisexual and plants are most often either male or female. 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 arranged in racemes and can produce hundreds of seeds ...

Partial Agonist
In pharmacology, partial agonists are drugs that bind to and activate a given receptor, but have only partial efficacy at the receptor relative to a full agonist. They may also be considered ligands which display both agonistic and antagonistic effects—when both a full agonist and partial agonist are present, the partial agonist actually acts as a competitive antagonist , competing with the full agonist for receptor occupancy and producing a net decrease in the receptor activation observed with the full agonist alone. Clinically, partial agonists can be used to activate receptors to give a desired submaximal response when inadequate amounts of the endogenous ligand are present, or they can reduce the overstimulation of receptors when excess amounts of the endogenous ligand are present. Some currently common drugs that have been classed as partial agonists at particular receptors include buspirone, aripiprazole, buprenorphine, nalmefene and norclozapine. Examples of ligands acti ...
