THC, or tetrahydrocannabinol, is the main psychoactive element in cannabis. THC attaches to cannabinoid receptors throughout the body and brain, and affects a person's memory, coordination, movements, thinking, perception, focus, sensory and time perception. THC is one of the 60-80 chemicals found in marijuana resin.The psychoactive cannabinoid compound delta-9-tetrahydrocannabinol (THC) is one of many chemical compounds, or cannabinoids, which are produced in tiny glands known as trichomes that are found on the cannabis plant. Delta-9-tetrahydrocannabinol is one of over 100 cannabinoids that have been identified in the cannabis plant.Delta 9-tetrahydrocannabinol, or THC, is the primary chemical responsible for the psychoactive effects of cannabis. When this cannabinoid enters the body, it begins a process that leads to feelings of euphoria and relaxation. If you consume marijuana and you suffer from a condition like epilepsy, which causes frequent seizures, you might hope to avoid the use of THC-dominant strains as CBD can actually help counteract some of these episodes.Delta-9-tetrahydrocannabinol (THC), or delta-nine-tetrahydrocannabinol, is the principal psychoactive ingredient in marijuana.Delta-8 THC , delta-9 THC , and delta-10 THC are the three unique variations of tetrahydrocannabinol (THC) found in Cannabis ruderalis. Each one of them differs from another in their psychoactive effects, as well as pharmacological properties. Just like variations in Cannabis indica and sativa, variations in C. ruderalis also arises from the different genes resulting in a different amount of each one of these compounds present in the plant.Delta-9 tetrahydrocannabinol (THC) is the main psychoactive chemical found in cannabis. Pharmacologically, it acts as a partial agonist at both the CB1 and CB2 receptors.In some marijuana plants, the highest concentration of THC is found in the female flowering tops (the plant equivalent of pollen) and in the surrounding leaves. The potency of each product can vary greatly, depending on the THC content.All plants possess resin-bearing glands--not just those in the flowering tops of sinsemilla plants. This resin is a mixture of cannabinoids (such as tetrahydrocannabinol, or THC) and a wide variety of terpenoids (the essence of a plant), which give the various marijuana strains their distinctive scents and flavors.
