In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon. Hydrocarbons are examples of group 14 hydrides. Hydrocarbons from which one hydrogen atom has been removed are functional groups called hydrocarbyls. Hydrocarbons are generally colourless and hydrophobic with only weak odours. Because of their diverse molecular structures, it is difficult to generalize further. Most anthropogenic emissions of hydrocarbons are from the burning of fossil fuels including fuel production and combustion. Natural sources of hydrocarbons such as ethylene, isoprene, and monoterpenes come from the emissions of vegetation.
Organic chemistry is a branch of chemistry that studies the structure, properties and reactions of organic compounds, which contain carbon in covalent bonding. Study of structure determines their chemical composition and formula. Study of properties includes physical and chemical properties, and evaluation of chemical reactivity to understand their behavior. The study of organic reactions includes the chemical synthesis of natural products, drugs, and polymers, and study of individual organic molecules in the laboratory and via theoretical study.
Petroleum, also known as crude oil and oil, is a naturally occurring, yellowish-black liquid found in geological formations beneath the Earth's surface. It is commonly refined into various types of fuels. Components of petroleum are separated using a technique called fractional distillation, i.e. separation of a liquid mixture into fractions differing in boiling point by means of distillation, typically using a fractionating column. It consists of naturally occurring hydrocarbons of various molecular weights and may contain miscellaneous organic compounds. The name petroleum covers both naturally occurring unprocessed crude oil and petroleum products that are made up of refined crude oil. A fossil fuel, petroleum is formed when large quantities of dead organisms, mostly zooplankton and algae, are buried underneath sedimentary rock and subjected to both intense heat and pressure.
Tetrahydrocannabinol (THC) is one of at least 113 cannabinoids identified in cannabis. THC is the principal psychoactive constituent of cannabis. 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. Like most pharmacologically active secondary metabolites of plants, THC is a lipid found in cannabis, assumed to be involved in the plant's evolutionary adaptation, putatively against insect predation, ultraviolet light, and environmental stress.
Hexane is an organic compound, a straight-chain alkane with six carbon atoms and has the molecular formula C6H14.
The effects of cannabis are caused by chemical compounds in the cannabis plant, including 400 different cannabinoids such as tetrahydrocannabinol (THC), 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.
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. Preliminary evidence suggests that cannabis can reduce nausea and vomiting during chemotherapy, improve appetite in people with HIV/AIDS, and reduce chronic pain and muscle spasms.
Cannabinoids are compounds found in cannabis. The most notable cannabinoid is the phytocannabinoid tetrahydrocannabinol (THC), the primary psychoactive compound in cannabis. Cannabidiol (CBD) is another major constituent of the plant. There are at least 144 different cannabinoids isolated from cannabis, exhibiting varied effects.
A polycyclic aromatic hydrocarbon (PAH) is a hydrocarbon—a chemical compound containing only carbon and hydrogen—that is composed of multiple aromatic rings. The group is a major subset of the aromatic hydrocarbons. The simplest of such chemicals are naphthalene, having two aromatic rings, and the three-ring compounds anthracene and phenanthrene. The terms polyaromatic hydrocarbon or polynuclear aromatic hydrocarbon are also used for this concept.
Cannabidiol (CBD) is a phytocannabinoid discovered in 1940. It is one of 113 identified cannabinoids in cannabis plants and accounts for up to 40% of the plant's extract. As of 2019, 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.

A flame ionization detector (FID) is a scientific instrument that measures analytes in a gas stream. It is frequently used as a detector in gas chromatography. The measurement of ion per unit time make this a mass sensitive instrument. Standalone FIDs can also be used in applications such as landfill gas monitoring, fugitive emissions monitoring and internal combustion engine emissions measurement in stationary or portable instruments.
Fort Griffin, now a Texas state historic site as Fort Griffin State Historic Site, was a US Cavalry fort established 31 July 1867 by four companies of the Sixth Cavalry, U.S. Army under the command of Lt. Col. S.D. Sturgis, in the northern part of West Texas, specifically northwestern Shackelford County, to give settlers protection from early Comanche and Kiowa raids. Originally called Camp Wilson after Henry Hamilton Wilson, a recently deceased lieutenant, it was later named for Charles Griffin, a former Civil War Union general who had commanded, as de facto military governor, the Department of Texas during the early years of Reconstruction.
Fort McKavett State Historic Site is located in Menard County, Texas, United States. Fort McKavett was a frontier fort established as Camp on the San Saba in 1852 to protect settlers from Indian raids. The camp was renamed in honor of Captain Henry McKavett, who was killed in the Mexican–American War battle of Monterrey.
JWH-176 is an analgesic drug which acts as a cannabinoid receptor agonist. Its binding affinity at the CB1 receptor is 26.0 nM, making it more potent than THC itself, however JWH-176 is particularly notable in that it is a hydrocarbon containing no heteroatoms. This demonstrates that reasonably high-affinity cannabinoid binding and agonist effects can be produced by compounds with no hydrogen bonding capacity at all, relying merely on Van der Waals interactions to bind to the receptor. It was discovered by, and named after, John W. Huffman.
Hash oil, also known as honey oil or cannabis oil, is an oleoresin obtained by the extraction of cannabis or hashish. It is a cannabis concentrate containing many of its resins and terpenes – in particular, tetrahydrocannabinol (THC), cannabidiol (CBD), and other cannabinoids. There are various extraction methods, most involving a solvent, such as butane or ethanol. Hash oil is usually consumed by smoking, vaporizing or eating. Hash oil may be sold in cartridges used with pen vaporizers. Preparations of hash oil may be solid or colloidal depending on both production method and temperature and are usually identified by their appearance or characteristics. Color most commonly ranges from transparent golden or light brown, to tan or black. Cannabis retailers in California have reported about 40% of their sales are from cannabis oils. Hash oil is an extracted cannabis product that may use any part of the plant, with minimal or no residual solvent. It is generally thought to be indistinct from traditional hashish, according to the 1961 UN Single Convention on Narcotic Drugs, as it is "the separated resin, whether crude or purified, obtained from the cannabis plant".
11-Nor-9β-hydroxyhexahydrocannabinol, is a synthetic cannabinoid derivative which resulted from early modifications to the structure of THC, in a search for the simplest compound that could still fulfil the binding requirements to produce cannabis-like activity. HHC is active in its own right with similar potency to THC, but further simplification and variation of this parent structure lead to more potent, yet structurally simpler derivatives such as CP 47,497 and CP 55,940, which after several steps of modification have become quite structurally distinct from THC, while HHC on the other hand is still substantially similar in structure to THC.
The Sheraton Gunter Hotel is a historic hotel in Downtown San Antonio, Texas, USA built in 1909 and designed by St. Louis architect John Mauran. It is listed on the National Register of Historic Places.
Occupational health concerns over the use of cannabis among workers are becoming increasingly important as cannabis becomes legal in more areas of the US. Of note, employers have concerns of workers either coming to work acutely impaired or recent use of cannabis still being detected in the body. Employment issues such as ADA law as it relates to accommodations for cannabis, paying unemployment benefits or paying out workers compensation benefits and disability claims are all important issues. While federal law still prohibits use, employers in different states have taken different stances based on whether they are federal contractors, perform safety sensitive work or whether the cannabis use is acutely impairing the employee.
