Close up of a Cannabis plant. Cannabis (/ˈkænəbɪs/) is commonly known as marijuana or hemp and has two known strains: Cannabis sativa and Cannabis indica, both of which produce chemicals to deter herbivory. The chemical composition includes specialized terpenes and cannabinoids, mainly tetrahydrocannabinol (THC), and cannabidiol (CBD ...
A dried cannabis flower. The short-term effects of cannabis are caused by many chemical compounds in the cannabis plant, including 113 [clarification needed] different cannabinoids, such as tetrahydrocannabinol, and 120 terpenes, [1] which allow its drug to have various psychological and physiological effects on the human body.
Cannabis plants produce a large number of chemicals as part of their defense against herbivory. One group of these is called cannabinoids , which induce mental and physical effects when consumed . Cannabinoids, terpenes , terpenoids , and other compounds are secreted by glandular trichomes that occur most abundantly on the floral calyxes and ...
[4] [5] Cannabis plants can produce volatile organic compound in great enough amounts to increase the criteria air pollutants in indoor and outdoor environments. [6] This could create an occupational health hazard in areas with large numbers of plants. [6] Cannabis in California is a frequent focus of study.
The mixture of cannabinoids produced by a plant is known as the plant's cannabinoid profile. Selective breeding has been used to control the genetics of plants and modify the cannabinoid profile. For example, strains that are used as fiber (commonly called hemp ) are bred such that they are low in psychoactive chemicals like THC.
Many of these plants are used intentionally as psychoactive drugs, for medicinal, religious, and/or recreational purposes. Some have been used ritually as entheogens for millennia. [1] [2] The plants are listed according to the specific psychoactive chemical substances they contain; many contain multiple known psychoactive compounds.
The first PFAS compounds were made in labs in the 1940s. Over decades of use, they are now so pervasive that they are detectable in household dust, drinking water, and even our blood.
The overall chemical reaction is: CBGA + O 2 THCA + H 2 O 2. Chemical structure of tetrahydrocannabinolic acid (THCA), the product of THCA synthase. A hydride is transferred from CBGA to reduce FAD, concerted by deprotonation of a hydroxyl group by a tyrosine residue. The monoterpene moiety in CBGA is then positioned to complete cyclization ...
