THC (Tetrahydrocannabinol) is the primary psychoactive compound in cannabis, responsible for the "high" sensation. It interacts with the endocannabinoid system, particularly CB1 receptors in the brain, altering mood, perception, and cognition. Found in marijuana and some hemp strains, THC is used recreationally and medicinally for pain relief, appetite stimulation, and relaxation. Its potency varies depending on the strain, extraction method, and consumption form.

THC products should be kept in a cool, dark, and dry place to maintain potency and freshness. Store flower in airtight glass jars away from direct sunlight, while edibles and concentrates should be sealed properly to prevent degradation. Refrigeration may help extend the shelf life of tinctures and infused products. Always keep THC securely stored, out of reach of children and pets.
