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.
The Endocannabinoid System (ECS) regulates many functions of the human body. 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.
The effects last for two to six hours, depending on the amount used. At high doses, mental effects can include anxiety, delusions (including ideas of reference), hallucinations, panic, paranoia, and psychosis. There is a strong relation between cannabis use and the risk of psychosis, though the direction of causality is debated.
The actions of Δ 9-THC result from its partial agonist activity at the cannabinoid receptor CB 1 (K i = 40.7 nM [24]), located mainly in the central nervous system, and the CB 2 receptor (K i = 36 nM [24]), mainly expressed in cells of the immune system. [25] The psychoactive effects of THC are primarily mediated by the activation of (mostly G ...
The endocannabinoid system, broadly speaking, includes: Endocannabinoids, which are the physiological ligands, or connecting substances, for the cannabinoid receptors.The main endocannabinoids are anandamide (N-arachidonoylethanolamide) and 2-AG (2-arachidonoylglycerol), which are in the same class of chemical compounds, called N-acylethanolamines (NAEs).
Differences in the chemical composition of Cannabis varieties may produce different effects in humans. Synthetic THC, called dronabinol, does not contain cannabidiol (CBD), cannabinol (CBN), or other cannabinoids, which is one reason why its pharmacological effects may differ significantly from those of natural Cannabis preparations.
Parts-per-million cube of relative abundance by mass of elements in an average adult human body down to 1 ppm. About 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium ...
The human musculoskeletal system (also known as the human locomotor system, and previously the activity system) is an organ system that gives humans the ability to move using their muscular and skeletal systems. The musculoskeletal system provides form, support, stability, and movement to the body.
